  • Structures

    Rugged Cat structures are the backbone of the 777F off-highway truck’s durability.

    Box-Section Design

    The 777F frame uses a box-section design, incorporating two forgings and 19 castings in high-stress areas with deep penetrating and continuous wrap-around welds to resist damage from twisting loads without adding extra weight.

    • Steel Structures

    Mild steel used throughout the frame provides flexibility, durability and resistance to impact loads, even in cold climates, and allows for easy field repairs.

    • Castings

    Castings have large radii with internal reinforcing ribs to dissipate stress in areas of high stress concentration. Castings move welds to lower stress areas for greater frame life.

    Integral Four-Post ROPS Cab

    Resiliently mounted to the main frame with all-new cab mounts that reduce vibration and sound, the integral ROPS is designed as an extension of the truck frame. The ROPS/FOPS structure provides “five-sided protection” for the operator.

    Suspension System

    Designed to dissipate haul-road and loading impacts for longer frame life and a more comfortable ride.

    • Cylinders

    Four independent self-contained, oil pneumatic, variable-rebound suspension cylinders are designed to absorb shocks in the most severe applications.

    • Durable Design

    Rugged cylinders use a large diameter bore and low pressure nitrogen/oil design for long life with minimal maintenance.

    – Front

    Front cylinders with preset caster and camber are mounted to the frame and serve as steering kingpins for a tight turning radius with excellent maneuverability and low maintenance.

    – Rear

    Rear cylinders allow axle oscillation and absorb bending and twisting stresses caused by uneven and rough haul roads rather than transmitting them to the frame.

    Technology Enhanced

    Caterpillar structures are tested using System Structural Analysis (SSA) to dynamically simulate operations in field environments and identify potential structural improvements in high stress areas. With analysis of machine structures and variables, such as haul road and payload, structural improvements were made to the frame to accommodate the new cab, platform, engine and radiator.

The cylinder head is a one piece, cast iron component with a newly designed graphite and steel composite head gasket that seals the combustion chamber with better rigidity and wear capability.

    Overhead Cam

    A single overhead cam is driven by gears on the front of the engine, which significantly reduce noise and vibration. Caterpillar also has added two pendulum absorbers, mounted at the front of the camshafts to further reduce noise and vibration.

    Turbochargers

    The single, waste-gated turbocharger found on the C15 engine is water-cooled to accommodate sudden hot machine shutdowns. Water cools the bearings during this event, preventing bearing seizure. The C15 engine also includes a new turbine housing and an additional spacer bearing. The addition of a spacer bearing eliminates snap rings and, therefore, reduces complexity and improves shaft motion. The turbocharger uses an aluminum compression wheel. Changes enable the C15 to deliver longer life and lower maintenance costs and contribute to good fuel economy. The design also provides high horsepower with improved response time while keeping exhaust temperatures low for long hours of continuous operation. The waste-gate turbocharger design improves engine response and peak torque, while providing higher boost over a wider range.

    Oil Coolers

    The 770 is equipped with three oil coolers: an engine-mounted engine oil cooler, an engine-mounted transmission/torque converter oil cooler, and a remote-mounted, brake, hoist and hydraulic fan oil cooler. These coolers allow major components to expel heat, maintaining optimal operating temperatures.

    Fuel Filters

    The C15 engine is equipped with two fuel filters. The primary filter is machine-mounted and features oil/water separation and an electric priming pump. The electric pump provides easier priming and better contamination control than a manual unit. The secondary fuel filter is also machine mounted, and has a switch that monitors pressure changes and provides pressure drop warnings to the operator.

    Advanced Diesel Engine Management A4 Engine Controller

    The ADEM™ A4 electronic control module provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs.

    Next Generation Modular Radiator (NGMR)

    The new modular cooling system with a single-pass flow core design uses brazed construction for stronger joints, better leak prevention and higher heat transfer. The simpler design of the single-pass system, which replaces the two-pass flow folded core system enables coolant to enter one end of the core and flow out the opposite end for more efficient ambient cooling capability and greater durability.

    Hydraulic Demand Fan & Accessory Drive

    The 770 includes a standard, variable-speed, on-demand fan. This fan provides cooling airflow only when necessary, resulting in reduced parasitic losses, a reduction of fuel consumption and fan-generated noise. The C15 engine includes a Poly-V accessory drive belt with an auto-tensioner, which is self adjusting.

    Block

    The C15 block incorporates a one-piece, grey iron block, featuring generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength. Caterpillar also has moved away from pipe thread ports to straight-thread, o-ring connection points, reducing the potential for leaks. This new design supports the engine’s higher compression ratios and increased power density.

    Pistons, Connecting Rods, Cylinder Liners

    New design and material improvements to the pistons, rods and liners have been made to support the higher cylinder pressures and the 18:1 compression ratios associated with ACERT Technology, while still providing durability to engine overhaul. A single-piece steel piston, pulsator-tested to 4,000 psi, is matched to a robust connecting rod to ensure long component life. The piston’s steel skirt increases its durability and results in reduced thermal expansion, allowing a tighter piston fit and reduced liner vibration. The overall piston surface area reduces friction and enhances fuel economy. The newly designed connecting rod allows better lubrication and cooling and is more securely fastened to the crankshaft using two additional bolts. The new improved rod bearings are made of steel-backed copper alloy with lead tin overlay. This new metallurgy reduces flaking and offers better fatigue strength. Cylinder liners are wet liners made of compacted graphite and iron for excellent wear and strength characteristics. Also, the tolerances between the pistons and the wet cylinder liners have been tightened to unprecedented levels for reduced blow-by and higher efficiency.

    MEUI Fuel System

    The Cat MEUI fuel system combines the technical advancement of electronic control with the simplicity of direct mechanically controlled unit fuel injection. This system electronically controls injection pressure by sensing the engine speed and load conditions over the entire engine operating speed range. A low-pressure fuel transfer pump provides fuel to the injectors, which then increases the pressure to deliver very fine, atomized fuel particles into the combustion chamber with precise timing and duration. The result is a more complete fuel burn with lower emissions and better engine response.

    Power Train — Transmission

    Cat power train delivers more to the ground for greater productivity and lower operating costs.

    Mechanical Power Train

    The Cat mechanical drive power train and power shift transmission provides unmatched operating efficiency and control on steep grades, in poor underfoot conditions, and on haul roads with high rolling resistance.

    Transmission

    Pairing the Caterpillar seven-speed planetary power shift transmission with the C15 diesel engine with ACERT Technology delivers constant power over a wide range of operating speeds.

    • Transmission Chassis Control (TCC)

    Transmission shifting is based on Transmission Output Speed for optimum performance efficiency and clutch life. The TCC provides integrated functionality to controlled throttle shifting, directional shift management, neutral coast inhibitor, body-up shift limiter and body-up reverse neutralizer.

    Throttle Lock

    The operator can now electronically lock the throttle pedal at full throttle, to reduce fatigue on long uphill hauls. The throttle can be locked on by momentarily depressing the throttle lock switch located on the operator console, while depressing the pedal fully. The throttle is released whenever braking is applied or the throttle is again depressed.

    Lock-Up Torque Converter

    Combines maximum rimpull and cushioned shifting of torque converter drive with the efficiency and performance of direct drive. The torque converter includes: an additional clutch plate to maintain power train capability for higher horsepower and top speed, a new torque converter adapter that provides extra length to house the additional clutch plate and enables the converter components to be changed without having to change the housing, and a new sump oil level switch that serves as an emergency warning if oil is lost. The lock-up torque converter engages at approximately 8 km/h (5 mph), delivering more power to the wheels.

    Lock-Up Clutch

    Quickly releases and re-engages to reduce power train torque loads for smoother shifting, long life and a more comfortable ride.

    New Differential and Proven Final Drives

    The new Cat differential works with the proven final drives as a system to deliver maximum power to the ground. For improved serviceability, the pinion gear is cantilever mounted, which allows inspection of the differential without pulling the rear-end. Visual inspection of the pinion gear and bearings can be performed in 1-2 hours versus 8 hours on the previous models. In addition, the differential bevel pinion gear set is designed for improved adjustability, which results in improved contact patterns and life. The differential gear set also provides enhanced bending life for steeper grade applications.

    New Differential Center Housing

    A new, ductile iron center housing improves quality and reliability. The improved stiffness allows for better main support bearing life. The new housing also uses bolts, reducing maintenance time. This change also improves wheel station bolted-joint life.

    New A-Frame

    The new A-frame mounts directly to the spindles. The new A-frame eliminates the “king” bolt and includes a pin and bushing style mounting, consistent with the 777 and 793. This new design is simpler to maintain and service.

    New Ductile Iron Spindles

    A stress-optimized, ductile iron spindle is splined to the rear brakes, reducing brake pack rebuild time by up to two hours. In addition, the spindles are longer and wider with fewer seals for increased strength and durability.

    Tires

    The 770 uses 18.00R33 tires as the standard tire configuration.

    • Steering System

    Hydraulic steering control system is designed for exceptional smoothness and precise control. A separate circuit prevents cross contamination for long life.

    • Battery Powered Supplemental Steering

    A battery powered supplemental steering system uses pressure accumulators and allows up to three 90 degree turns in case of engine failure.

    • Wheels and Rims

    Cast rear wheels and Cat center-mount rims are mounted using studs and nuts to minimize maintenance and maximize durability.

    Wheel Stations

    The wheel stations now integrate both the wheel and the hub. The single-piece design reduces removal and installation time, and the risk of brake cooling oil leakage. The inner Duo-cone™ seal has been changed from a formed type to a cast design. Brake cooling flow and the Duo-cone seal has also been reversed for better sealing performance and improved seal life. Wheel stations are now interchangeable, reducing the number of replacement parts: left and right wheel stations are symmetric and can be interchanged. In addition, the new design eliminates one o-ring seal, which improves reliability and simplifies the system and the wheel bearings have been enhanced for longer bearing life.

    Brake Packs

    A single-piece brake anchor eliminates more than 200 fasteners and a row of bolted joints. Rebuild time is reduced by up to two hours. In addition, the brake pack is removable without taking the spindle off the truck. The 770 features 24 brake discs. The brake discs have increased in diameter from 19 to 21 in (482.6 to 533.4 mm). By increasing the diameter, Caterpillar has improved the overall reliability and durability of the brake packs and has also designed the brake packs to improve the OD/ID ratio. The new 770 brake pack design, moves the braking forces to the outer edge of the disc, thereby using greater surface area for improved braking forces and longer life, improving reliability and lowering maintenance cost.

    Structures

    Rugged Cat structures are the backbone of the 770 off-highway truck's durability.

    Box-Section Design

    The 770 frame uses a box-section design, incorporating two forgings and 13 castings in high-stress areas with deep penetrating and continuous wrap-around welds to resist damage from twisting loads without adding extra weight.

    • Steel Structures

    Mild steel used throughout the frame provides flexibility, durability and resistance to impact loads, even in cold climates and allows for easy field repairs.

    • Castings

    Castings have large radii with internal reinforcing ribs to dissipate stress in areas of high stress concentration. Castings move welds to lower stress areas for greater frame life.

    Integral Four-Post ROPS Cab

    Resiliently mounted to the main frame with all-new cab mounts that reduce vibration and sound, the integral ROPS is designed as an extension of the truck frame. The ROPS/FOPS structure provides “five-sided protection” for the operator.

    Superior Weld Quality

    Structural frame welds are J-groove type, ensuring full weld penetration for strength and longevity. During fabrication, weld integrity is further enhanced by rotating the frames 360 degrees to provide optimal, flat welding surfaces.

    Technology Enhanced

    Caterpillar structures are tested using System Structural Analysis (SSA) to dynamically simulate operations in field environments and identify potential structural improvements in high stress areas. With analysis of machine structures and variables, such as haul road and payload, structural improvements were made to the frame to accommodate the new cab, platform, engine and radiator.

    Quality Control

    A Coordinate Measuring Machine (CMM) is used to inspect truck frames for consistency in the manufacturing process. In addition, all critical welds receive testing to verify weld penetration, which results in frame durability.

    Forgings and Castings

    • The 770 features a drop tube/casting design and two forged steel mountings for hoist cylinders, similar to the design as found on the 773.
    • A volcano casting that holds the center tube is enhanced with thicker wall dimensions for increased durability.
    • New strut-mount castings have been moved 10 in (254 mm) forward and 1 in (25.4 mm) outward on each side. These thicker strut-mount castings and their location improve ride characteristics as well as durability.
    • New steering casting (same as 773) accommodates larger steering cylinders and ball studs.
    • New tail casting accommodates new angled rail design.

    Engine — Power Train Integration

    This system electronically combines critical power train components to work together more intelligently to optimize overall truck performance.

    Economy Shift Mode

    Modifies engine maps for better fuel economy.

    Body-up Shift Limiter

    Prevents the transmission from shifting above a pre-programmed gear without the body being fully lowered. This function is programmable via Cat Electronic Technician (Cat ET) and Messenger.

    Body-up Reverse Neutralizer

    Automatically shifts the transmission to neutral if the hoist lever is activated while the transmission is shifted in reverse.

    Programmable Top Gear

    Transmission top gear maximum can be set using Cat Messenger or the Cat ET service tool to help the operator maintain speed limits.

    Reverse Shift Inhibitor

    Protects the engine from abrupt directional changes by slowing down the engine before shifting the transmission into reverse.

    Cat Data Link

    Electronically integrates machine computer systems to optimize overall power train performance, increase reliability and component life, and reduce operating costs. All the information from these controls can be accessed through a laptop computer with Cat ET.

    Transmission Chassis Control (TCC)

    TCC uses electronically transferred engine rpm data to execute shifts at preset points for optimum performance, efficiency and clutch life.

    Electronic Technician (Cat ET)

    Cat ET service tool provides service technicians with easy access to stored diagnostic data through the Cat Data Link to simplify problem diagnosis and increase machine availability. Cat ET is beneficial because of how it displays the status of all engine parameters, including throttle position, timing and fuel flow. Critical data from the electronic engine and transmission controls, including transmission shifting, engine speed and fuel consumption, provides service technicians with enhanced diagnostic capability to reduce downtime and operating costs.

    Controlled Throttle Shifting

    Regulates engine rpm during shifting to reduce power train stress and clutch wear by controlling engine speed, torque converter lock-up and transmission clutch engagement for smoother shifts and longer component life.

    Directional Shift Management

    Regulates engine speed during directional shifts to prevent damage caused by high-speed directional changes.

    Neutral Coast Inhibitor

    Prevents the transmission from shifting to neutral at speeds above 6.5 km/h (4 mph), protecting the transmission from operating with insufficient lubrication.

    Overspeed Protection.

    The transmission control electronically senses engine conditions and automatically up-shifts one gear to prevent overspeeding. If overspeeding occurs in the top gear, the lock-up clutch is disengaged, and the brakes are applied.

    Anti-Hunt Function

    This function minimizes shifting by not allowing the transmission to up or down shift immediately after a shift has occurred. This prevents gear hunting when operating near a shift point and minimizes transmission shifting for increased component life.

    Downshift Inhibitor

    Prevents engine overspeeding by keeping the transmission from downshifting until engine speed reaches the downshift point.

    Cat Messenger

    Critical data from the engine and transmission, including transmission shifting, engine speed and fuel consumption, provides service technicians with enhanced diagnostic capability, through Cat Messenger, to reduce downtime and operating costs.

    Traction Control System (TCS) (Optional)

    TCS electronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions.

    Hydraulic Power Management System

    The system reduces parasitic losses in the power management system components. The system is operated by two new variable displacement piston pumps. These pumps primarily provide for the steering and are independent of the brake and hoist circuit.

    Brake System

    Reliable braking with superior control gives the operator the confidence to focus on productivity.

    Full Hydraulic Service Brake

    The 770 features a full hydraulic brake system, which offers significant improvements in reliability, response, control and serviceability versus an air-over hydraulic system. There are fewer components (part by part comparison), boosting reliability and streamlining maintenance.

    Improved Reliability

    Because oil is now used to actuate the brakes, Caterpillar has eliminated the need for two brake master cylinders, two relay valves, an air dryer and the retarder valve (found on ARC trucks only) that were associated with the air-over-hydraulic brake system. The air system had complexity which affected its reliability. The oil actuated system is simpler and more reliable.

    Extended Life Multiple Disc Brakes (optional)

    Extended life friction material has double the wear life of standard brakes and is twice as resistant to glazing for more consistent braking power with less noise.

    Brake Design

    Cat rear oil-cooled disc brakes are designed with large discs and plates for reliable, adjustment-free operation and performance. Rear brakes are completely enclosed and sealed to prevent contamination and reduce maintenance.

    Long Life

    An oil film prevents direct contact between the discs. This design absorbs the braking forces by shearing the oil molecules and carrying heat away to extend brake life.

    Pistons

    The Caterpillar two-piece piston design combines the service, secondary, parking brake and retarding functions in the same system. The primary piston hydraulically actuates both service and retarding functions. The secondary piston is spring-applied and held in the disengaged position by hydraulic pressure. If hydraulic system pressure drops below a specified level, the spring-applied secondary piston automatically applies the brakes.

    Parking Brake

    Oil-cooled, spring-applied, hydraulically released parking brake is applied to the rear wheels for superior parking capability on all grades up to 15 percent.

    Automatic Retarder Control (ARC)

    Standard ARC electronically controls braking on grade to maintain engine at approximately 1,900 rpm (adjustable from 1,850-1,950 rpm in increments of 10). ARC is deactivated when the operator applies the brakes or throttle.

    • Faster Speeds

    ARC allows the operator to maintain optimum engine speeds for up to 15 percent faster downhill hauls and greater productivity.

    • Superior Control

    Automatic brake modulation offers a smoother ride and better control in slippery conditions, allowing the operator to concentrate on driving.

    • Ease of Operation

    ARC increases operating ease, resulting in greater operator confidence with less fatigue.

    • Engine Overspeed Protection

    Automatically activates ARC when engine speed exceeds factory preset levels, regardless of operator inputs, to avoid potentially damaging engine overspeeds.

    Traction Control System (TCS) (optional)

    Electronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions. If slippage exceeds a set limit, the oil-cooled disc brakes engage to slow the spinning wheel. Torque is then automatically transferred to the wheel with better traction.

    Compression Brake (optional)

    Optional Compression Brake is integrated with Automatic Retarder Control (ARC) to provide up to 35 percent higher downhill travel speed and reduce wear on brake components.

    Oil-Cooled Multiple Disc Brakes

    Cat dry front and rear oil-cooled, multiple disc brakes are now hydraulically controlled, reducing maintenance costs. The 770 brakes provide exceptional, fade-resistant braking and retarding for maximum performance and productivity in all haul-road conditions.

    Hydraulic Accumulators

    The brake system is equipped with a primary accumulator and a secondary accumulator, which also provides back-up braking in the event of a failure. The accumulators automatically drain pressure after shutdown, reducing the service time by removing the need to drain the pressure off the system and reducing the risk of high-pressure exposure during maintenance. The new brake system uses a pump that is driven off the flywheel 100 percent of the time and is only loaded when hydraulic pressure falls below 1,600 psi. The pump will cut out at 1,975 psi. In the new system, oil in this circuit is also sent to the hydraulic fan system. Any additional oil is sent to the brake cooling system along with the oil used in the drive fan.

    Operator's Station

    Ergonomically designed for operator comfort, superior control and high productivity.

    Ergonomic Layout

    The 770 operator's station is ergonomically designed for total machine control in a comfortable, productive and safe environment. All controls, levers, switches and gauges are positioned to maximize productivity and minimize operator fatigue.

    New ISO Designed Cab Mounts

    Integral, sound-suppressed cab is resiliently mounted to the frame to isolate the operator from sound and vibration for a quiet, secure and comfortable ride.

    All New Center-Mounted Cab

    Center cab positioning provides additional room and creates a walk-in-style cab. The new configuration allows the operator to easily enter and exit the cab. The cab environment offers a spacious surrounding, giving the operator the ability to stretch out and providing superior comfort for an entire operating shift. The operator seat is located on the right hand side of the cab with the trainer to the immediate left.

    Viewing Area

    Designed for excellent all-around visibility and clear sight lines to the haul road. The large viewing area, with 52 percent more glass, enables the operator to maneuver with confidence for greater productivity.

    Trainer Seat

    By moving the trainer seat to the left of the operator, the trainer may enter/exit the vehicle using the same stairway door as the operator. When not in use, the fold-down trainer seat creates a working surface with cup holder. Under seat storage is convenient for stowing a lunch box.

    Operator Controls

    Easy to reach turn signal, high beam, intermittent windshield wiper and windshield washer controls are located on the left side of the steering column, and are designed for optimum efficiency and comfort.

    Radio Ready

    Cab is prewired with power converter, speakers, wiring harness, antenna and necessities for add-on communication systems.

    Multiple Power Ports

    Power ports are conveniently located in three locations in the cab: one in the right-hand console, two behind the trainer seat, and one in the dash.

    Truck Production Management System (TPMS) (Optional)

    TPMS provides valuable payload and cycle time data, which is viewed through Messenger. Now the system provides 2,400 cycles, as opposed to the previous 1,400 cycles, and takes a second payload measurement when the truck reaches second gear for increased accuracy. Standard LED lamps replace incandescent lamps on the TPMS, extending lamp life by 25 times.

    Serviceability

    Less time spent on maintenance means more time on haul roads.

    Cat Data Link

    A Cat Data Link port located near the fuse panel in the cab can access all electronic controls for obtaining monitoring and diagnostic data. Excellent access to the ECM and electrical panels improves the ability to perform maintenance and trouble-shoot the cab electronics.

    • Engine Starter Lockout Switch

    Power is available to the machine, but it cannot be started.

    • Transmission, Hoist and Steering Lockout Switch

    The 770 features an all-new transmission, hoist and steering lockout mode. This feature disables the steering, hoist and transmission hydraulics, and sets the parking brake while the engine is running, allowing maintenance and trouble-shooting on the truck. The operator can use this feature to take S•O•SSM analysis samples.

    • Electrical Breakers

    Ground-level access to circuit breakers are now provided for engine control, alternator and main electrical breakers.

    Scheduled Oil Sampling

    S•O•SSM sampling valves speed sampling and analysis reliability.

    Oil Filter

    The 770 has one engine oil filter on the right-hand side of the engine. This filter is located for easy serviceability. The oil filter is a 5-micron filter and features a 500-hour oil change interval.

    Electrical Access

    The 770 features a new configuration for fuses, circuit breakers and rear cab-mounted relays, enabling up to 50 percent faster servicing. A 12-Volt and 24-Volt power port are included. The automotive-style fuses, which replace the screw-in type, are all incorporated into a single enclosure that is easily accessible from inside the cab. 10-amp and 15-amp spare fuses are also included in the new design.

    Service Switches

    Machine switches and an auxiliary start receptacle offer easier access and expanded capabilities. The battery disconnect switch, and auxiliary start receptacles are now combined into the same modular assembly and relocated for ground access. Also, a new service panel on the LH front of the machine provides:

    Cat ET

    Cat ET service tool provides service technicians with easy access to stored diagnostic data through the Cat Data Link to simplify problem diagnosis and increase machine availability. Cat ET is beneficial because of how it displays the status of all engine parameters, including throttle position, timing and fuel flow. Critical data from the electronic engine and transmission controls, including transmission shifting, engine speed and fuel consumption, provides service technicians with enhanced diagnostic capability to reduce downtime and operating costs.

    Lincoln’s Quick Lube Automatic Lubrication (optional)

    This advanced lubrication system is available as a factory installed option. This system provides optimal lubrication at preset intervals during machine operation significantly extends component life.

    Clustered Grease Fittings (Optional)

    Clustered grease fittings save time as all lubrication points are mounted in three main locations.

    Oil Dipstick

    New “rope-type” oil dipstick improves serviceability by allowing easy daily checks.

    QuickEvac™ System and Prelube System

    Oil change labor time is reduced by as much as 50 percent with this standard on-board engine oil evacuation and pre-lube system. This system automatically fills engine oil filters and galleries, which ensures components are lubricated prior to starting the engine.

    Extended Life Brake Discs (Optional)

    The extended life brake discs are made with a friction material that provides longer service life and increased heat resistance when compared to Caterpillar’s standard brake offerings. Discs use an innovative carbon paper for braking and can be expected to double the life of standard paper friction material in most conditions. This is a significant step forward, especially in long, downhill-loaded hauling applications. The material is also twice as resistant to glazing, which is common during periods of high-temperature braking in moderate to severe operating conditions. Resistance to glazing leads to more consistent braking power.

    Ground-Level Access

    All maintenance points have convenient ground level or platform access. Common engine service points are grouped on the right side of the engine for quick access. Two fuel filters come standard with the machine and the primary fuel filter includes a water separator. These filters are easy to change and are all spin-on/spin-off type. Engine oil check and fill are accessed via the service platform. The newly designed engine oil dipstick is “rope-type” style, making daily checks easier for the operator.

    Truck Body Systems

    Cat designed and built for rugged performance and reliability in the toughest hauling applications.

    Increased Body Capacities

    The 770 body capacity at 32.8 yd3 (25.1 m3), has increased 3.5 percent over the 769 at 31.7 yd3 (24.2 m3). Payloads are based on 2,800 lbs per LCY (1660 kg per lcm) material.

    Electronic Hoist Control

    Provides the operator with better control of the load when dumping, including over-center load control and modulated control throughout the operating range. The automatic body snubbing feature reduces impact on the frame, hoist cylinders and operator.

    Fast Hoist Cycle Times

    Two stage hoist cylinders provide fast dump cycle times of 9.5 seconds for raise and 12.5 seconds for lower.

    Steel-Lined Body System

    The traditional steel-lined system is well understood by users worldwide. In the new 770 steel body system, the unique design allows the floor and liner to work together to provide the impact and wear resistance. The Medium Impact, Steel Body System offers optimum combinations of wear and impact resistance, while maximizing performance. If the application dictates higher impact or wear needs, the High Impact, Steel Body System or the Heavy Duty, High Impact, Steel Body System provides more impact and wear resistance, but at an increase in body weight versus the Medium Impact, Steel Body System.

    • Impact

    Impact is the energy that is created by the material when it hits the truck body. The condition and size of material, combined with the height at which it is dropped, greatly determines the impact energy that the body must absorb. The most measurable effect of impact is structural bending, chipping, cracking, and spalling. These conditions can be created when the impact absorption capability is exceeded by the impact of the material itself. Generally speaking, a high impact material might be basalt or granite. A medium impact material might be mixture of decomposed rock (75 percent rock, 25 percent dirt), while a low impact material might simply be dry, packed dirt.

    Application Specific Body Systems

    With the introduction of the next generation of trucks, Caterpillar will build on the previous strengths and provide differentiation through six different body systems. Both dual slope and flat floor bodies will be available in the following configurations:

    • Low Impact, Steel Body System
    • Medium Impact, Steel Body System
    • High Impact, Steel Body System
    • Heavy Duty Impact, Steel Body System
    • High Impact, Rubber Body System
    • Heavy Duty High Impact, Rubber Body System

    Rubber-Lined Body System

    A new offering available from the factory is the rubber-lined body system. For impact resistance in hard-rock applications, rubber liners offer a practical, durable and cost-effective solution. They dissipate impact energy, maximizing body life and reduce noise, improving job site work conditions inside and outside the cab. These maintenance-free liners also require minimal installation time. The density of rubber is 20 percent of the density of steel, yet its ability to absorb impact is three times that of steel. This gives rubber a high impact strength-to-weight ratio. In addition, truck operators enjoy a better operator environment, without the hard impacts felt during loading.

    Body System Selection

    Two primary factors affect body selection:

    • Abrasion or Wear

    The tendency of a material to grind away the surface of a body by means of friction is abrasion. Abrasion occurs when a material’s hardness is higher than the wear surface that it slides on. A high abrasion material could be any rock material containing a high proportion of hard, angular minerals such as quartz. Granite tends to be highly abrasive. A moderate abrasion material might contain a high proportion of minerals such as calcite. Limestone is most likely in the moderately abrasive category. A low abrasion material could be any material that contains minerals such as talc.

    Exhaust Routing

    There are three exhaust routing systems available for the 770, depending on the customer’s requirements for body heat and sound:

    • Full-Time Body Routing

    The standard design provides full-time routing of exhaust into the body to heat areas where material gathers. This plays a crucial role in preventing material from being retained in the body during dumping. Not for use with rubber liner body systems.

    • Full-Time Muffler Routing

    The second option is the full-time routing of exhaust through a muffler, which eliminates exhaust in the body. This option should be used for rubber-lined bodies or applications that do not require body heat.

    Matched Systems

    Designed to work as an optimum pass/match system, the 770 is best sized to match the 988H Wheel Loader, with a 4 pass/match, the 990H Wheel Loader, with 3 pass/match, and the 385C Hydraulic Excavator with a 6 pass/match.

    Body Design

    The new dual slope and flat floor body systems will continue to use fully fabricated, mild steel structures, offering a strong, yet weldable underbody structure. All interior, steel body surfaces that come in contact with material are fabricated from 400 BHN steel to provide superior wear characteristics and resistance to impact. Wide box-section ribs provide excellent durability and impact support in the floor, front-wall, sidewall, and top rail areas. Full-length stringer rails enhance strength and rigidity throughout the body. Other new features that further enhance durability of the understructure include:

    • Sidewall ribs are integrated into the floor ribs, forming a belt to provide increased strength in the sidewalls.
    • Underbody ribs are increased from seven to nine, enhancing the underbody structural support.
    • Front wall body rest supports are integrated into the front wall structure for enhanced durability.
    • Full-length, single-piece stringer rails are used, improving the structural support in the body, especially in the body pivot support area.
    • Front wall is 400 BHN and the thickness is increased from 10.2 mm (0.4 in) to 16.0 mm (0.63 in), eliminating the need for additional liners for impact resistance in most applications.

    • Diverter Box Routing

    The final option provides a diverter box so that the customer has the flexibility to choose whether to route the exhaust through the body or directly to the outside. Both options go through the muffler. Not for use with rubber liner body systems.

    Target Payload Strategy

    Your Caterpillar Dealer can help you manage to target payload to maximize equipment use, ensure safe operation, increase productivity and lower cost-per-ton.

    • Underloading increases costs due to lost payloads, underutilizes equipment, and increases cost-per-ton.
    • Overloading causes excessive wear on vehicle components, such as brakes, tires and drive train, reducing component life and increasing maintenance costs and repairs.

    Safety

    Caterpillar machines and systems are designed with safety as the first priority.

    Product Safety

    Caterpillar has been and continues to be proactive in developing machines that meet or exceed safety standards. Safety is an integral part of all machine and systems designs.

    Integral ROPS Cab

    Resiliently mounted to the frame to reduce vibration and sound, the integral ROPS structure, which provides “five-sided protection” for the operator, is designed as an extension of the truck frame.

    Payload Guidelines

    Safety is integral to maintaining the highest productivity in mining machine operation. The Caterpillar 10/10/20 Payload Guidelines ensures that steering and braking systems have sufficient capacity to perform.

    WAVS Camera (Optional)

    An optional rear vision camera system provides visibility to the rear of the machine through an LCD monitor in the cab. The monitor an be set to activate only when the truck is in reverse, and the display is equipped with a sensor to detect ambient light, which automatically brightens or dims the display.

    Brake Systems

    Cat hydraulically controlled dry front and rear oil-cooled multiple disc brakes provide exceptional, fade-resistant braking and retarding for maximum performance and productivity in all haul-road conditions. The service brakes and retarding system are actuated by modulated hydraulic pressure, while secondary and parking brake functions are spring applied and hydraulic released. This reliable and durable system ensures braking in the event of complete hydraulic failure.

    Steering System

    A twin, double-acting cylinder steering system is designed to deliver precise control under all loading and underfoot conditions. The steering hydraulic system is separate from the main hydraulic system to prevent crosscontamination and overheating.

    Engine Shutoff Switch

    A secondary engine shutoff switch is located at ground level.

    Electrical System Disconnect

    A battery disconnect switch, located directly above the front bumper, provides ground-level lockout of the electrical system.

    Ladder/Secondary Egress

    Wide stationary stairways and platforms on both sides of the machine, allow easy ingress and egress.
