FEATURES & BENEFITS

Power Train – The updated Cat® C32 ACERT™ engine and powerful torque converter with ECPC (Electronic Clutch Pressure Control) Transmission provides superior performance. The ECPC Transmission with controlled throttle shifting regulates engine speed, torque converter lock-up and transmission clutch engagement for smoother shifts, reduced clutch wear and longer component life.Fuel Economy – The 777E fuel saving strategies find opportunities to reduce fuel burn and fuel costs. 1) Economy Mode modifies engine maps to take advantage of steady grades and level ground, reducing power and fuel burn. 2) Speed Limiting automatically selects the most fuel efficient gear and speed for the terrain instantaneously. 3) Engine Idle Shutdown identifies when the truck is in park and idles for more than a preset time, and initiates engine shutdown to conserve fuel.Engine Over Speed Protection – Electronically senses engine conditions and automatically up-shifts one gear to prevent over speeding. If over speeding occurs in the top gear, the lock-up clutch is disengaged, and the brakes are applied.Operator Comfort – The all new operator station interior 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. Designed for excellent all-around visibility and clear sight lines to the haul road, the large viewing area offers exceptional visibility. The well positioned hand rails ensure three point contact for safe and easy access and emergency egress for the operator.Diagnostic Capability – Critical power train data, including transmission shifting, engine speed and fuel consumption, provides service technicians with enhanced diagnostic capability to reduce downtime and operating costs.Electronic Technician (ET) – Cat ET service tool provides service technicians with easy access to stored diagnostic data through the Cat Data Link.Cab and Access – The 777E cab interior, is completely redesigned to provide better visibility and comfort for the operator. Features include a new dash, advisor display and redesigned center console. Rollover and Falling Object Protection is an extension of the truck frame.Operator Seat – The Cat Comfort Seat uses full air suspension to smooth rough rides, and has a retractable four-point seat belt with a shoulder harness. A Trainer seat with a lap belt to facilitate on-the-job training.Brakes – The Cat Front dry caliper with rear oil-cooled multiple disc brakes deliver reliable performance and control in the most extreme haul-road conditions. Wet brakes on rear wheels and gear limiting during body up operations are both standard. If equipped with front oil cooled multiple disc brakes, four corner retarding with a 40/60 percent front/rear split provides superior control in slippery conditions and minimizes wheel lock-up.Automatic Retarder Control (ARC) (optional) – ARC controls braking on grade electronically, maintaining consistent engine speed, lower fuel burn, and better control.Traction Control System (TCS) (optional) – The Traction Control System 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 rear wet brakes engage to slow the spinning wheel. Torque is then automatically transferred to the wheel with better traction and optimum control.Steering – Cat integrated steering and suspension system is designed for precise steering, excellent maneuverability, minimal tire wear and superior ride control.Secondary Steering – Automatically engages if power source for the normal steering fails.Durability – Rear wheel spindles are solid steel for longer life, and the rear suspension cylinders have been inverted to minimize contamination. These rugged cylinders use large diameter bore and low pressure nitrogen/oil design for long life with minimal maintenance.
