✔ ✔ ✔ pg. 9 pg. 10 pg. 12 Operators Station Engine Җ Power Train Integration Brake System The 770 features an all new operatorstation with enhanced visibility, increased operator space and ergonomically designed controls that setnew industrystandards for operator comfort. All controls and gauges are positioned for optimum efficiency andtotal machine control. The Cat Data Link electronicallycombines engine, transmission, brakeand operational information tooptimizeoverall truck performance. Stored diagnostic data can be accessed via the Cat Electronic Technician (CatET) service tool to improve...

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-testedto 25 560 kPa (4,000 psi), is matched to a robust connecting rod to ensure long component life. The pistons steel skirt increases its durability and results in reduced thermal expansion, allowing atighter piston fit and reduced liner vibration. The overall piston surface...

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. Thischange also improves wheel station bolted-joint life. Lock-Up Clutch. New Differential and Proven Final Drives. Quickly releases andre-engages to reduce power train torque loads for smoother shifting, long life and a more comfortable ride. The new Cat differential works with theproven final drives as a system to deliver maximum power to the ground. For improved serviceability,...

Tires. The 770 uses 18.00R33 tiresasthe standard tire configuration. Steering System. Օ Battery Powered SupplementalSteering. Wheels and Rims. A battery poweredsupplemental steering system uses pressure accumulators and allows uptothree 90 degree turns in case ofengine failure. Hydraulic steeringcontrol system is designed for exceptional smoothness and precise control. A separate circuit prevents cross contamination for long life. Cast rear wheels andCat center-mount rims are mounted using studs and nuts to minimize maintenance and maximize durability. Wheel Stations. The wheel stations nowintegrate...

Quality Control. A CoordinateMeasuring 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. Technology Enhanced. Caterpillarstructures 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...

Radio Ready. Multiple Power Ports. Truck Production Management System(TPMS) (Optional). Cab is prewired with powerconverter, speakers, wiring harness, antenna and necessities for add-on communication systems. TPMS providesvaluable 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 secondpayload measurementwhen the truck reaches second gear for increased accuracy. Standard LED lamps replace incandescent lamps on the TPMS, extending lamp life by 25 times. Power ports areconveniently located in...

Directional Shift Management. Regulates engine speed during directional shifts to prevent damage caused by high- speed directional changes. Neutral Coast Inhibitor. Prevents thetransmission from shifting to neutral atspeeds above 6.5 km/h (4 mph), protecting the transmission from operating with insufficient lubrication. Controlled Throttle Shifting. Regulatesengine rpm during shifting to reduce power train stress and clutch wear bycontrolling engine speed, torque converter lock-up and transmission clutch engagement for smoother shifts and longer component life. > 1 Engine Control Module (ECM)...

Traction Control System (TCS) (Optional). Hydraulic Power Management System. TCSelectronically monitors and controls rear wheel slippage for greater traction and enhanced truck performance in poor underfoot conditions. 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. Cat Messenger. Critical data from theengine and transmission, including transmission shifting, engine speed andfuel consumption, provides...

Long Life. An oil film prevents directcontact between the discs. This design absorbs the braking forces by shearing the oil molecules and carrying heat away to extend brake life. Oil-Cooled Multiple Disc Brakes. Catdry 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. Extended Life Multiple Disc Brakes(Optional). Brake Design. Extended life friction materialhas double the wear life of standard brakes...

Compression Brake (Optional). OptionalCompression Brake is integrated with Automatic Retarder Control (ARC) to provide up to 35 percent higher downhill travel speed and reduce wear on brake components. Traction Control System (TCS) (Optional). Ease of Operation. ARC increasesoperating ease, resulting in greater operator confidence with less fatigue. Օ Engine Overspeed Protection. 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...
