Overview

Redefining Performance.

The Cat® 777 Off-Highway Truck provides best in class productivity with upgraded engine, superior transmission controls, comfortable cabin, increased fuel economy and torque – designed to offer a durable and low-cost per-tonne option for your applications.

Benefits

Enhanced Comfort & Technology

Integrated hoist/shift controls, expanded Cat® Detect rear vision, and simplified touchscreen display to help make operation easier. Additional features include Cat® Detect seat belt reminder, enhanced Cat® Payload, and cycle segmentation.

Increased Fuel Efficiency

Help reduce operating costs with efficient operations. Features include part-throttle shifting, adaptive economy mode, engine idle shutdown, auto neutral idle, and speed limiting.

Improved Performance & Durability

Increased torque, hydraulic actuated brakes, and responsive Advanced Productivity Control System (APECS) transmission controls, traction control, and the C32B engine help support strong performance and durability.

Features At A Glance

Displaying 1-6 of 7

ACHIEVE GREATER PRODUCTIVITY

Productivity improvement up to 5%.
Advanced Productivity Electronic Control Strategy (APECS) transmission controls carry more torque through the shifts, producing faster cycle times, most noticeably on grades.
Machine speed limit feature allows the machine to run at an optimal gear for the selected speed.
Auto stall assists in quickly bringing the transmission to an operating temperature at start-up when the machine is working in a cold climatic region.
Second gear start skips first gear engagement depending upon underfoot conditions, improving the cycle time, minimizing the number of shifts, and running the machine at an optimum speed at initial start.
Various body options along with liners and sideboard combinations offer flexibility to move a wide density of material without compromising on payload.
No engine derating required up to 3048 m (10,000 ft).

BOOST FUEL EFFICIENCY

Improved fuel economy due to optimized fuel mapping of the engine.
Configurable economy mode helps to fix the engine power reduction depending upon the application. Engine derate can bevaried from 0.5% to 15%.
Adaptive economy mode determines the most efficient engine operating point when the truck is operating at steady state condition. The most efficient operating point is determined by customer inputs on fuel saving to max expected production limitation.
Conserve fuel with integrated Engine Idle Shutdown by the engine automatically initiating when the truck is in park and idle for a preset amount of time.
Auto neutral idle saves fuel by reducing torque load when the engine is idling and minimizes the transmission component wear.

DESIGNED FOR SAFETY

Superior brake performance meets the latest brake standards –ISO 3450:2011.
Sturdy four-point mounted cabin meets ROPS/FOPS standards.
Four-point seat belt for operator and lap belt for trainer seat.
Seat belt indicator implements both visual and audible alerts to the operator when seat belt is not fastened.
Lockout features help the service technician to perform maintenance work on the machine with safe mode.
Secondary steering activates automatically in case of primary system failure.
Overload speed limiter works with truck payload system to reduce machine speed automatically when the truck is overloaded.
Integrated ladder access, extended catwalk, and aggressive tread plates on all steps ensure safe entry and egress.
Cat Detect system with cameras and radar monitors objects that appear within designated machine blind spots, helps safe machine operation.

EASY TO OPERATE

Next gen gear shift lever with integrated hoist and park brake controls for ease of operation.
Best-in-class touchscreen display for the operator to navigate through machine control system during interaction and service of the machine.
Improved rear visibility for the operator with new mirror package on both sides of the machine.

INTEGRATED CAT TECHNOLOGIES

Product Link™ system connects to each machine wirelessly, allowing you to monitor location, hours, fuel use, productivity, idle time, and diagnostic codes.
Vital Information Management System (VIMS™ ) – user friendly interface monitor is available in the cabin to monitor key parameters of the machine.
The enhanced Truck Production Management System (TPMS 2) delivers improved payload accuracy and advanced cycle segmentation through a dual A6:N2 architecture. This next- generation platform enables faster data transmission, enhanced connectivity, and supports digital fleet management capabilities.
Cat Detect - Factory fit radar - monitors objects that appear within designated machine blind spots when the machine is in neutral or reverse.

PROVEN RELIABILITY AND SERVICEABILITY

Hydraulically actuated brake system improves brake component life and reduces maintenance costs.
Convenient filters and fluid refill help make servicing of the machine faster.
New auto lubrication system to meet varying customer requirements by providing metered grease for all lube points on the machine without any manual intervention (optional attachment).
Hydraulic power port provides a quick disconnect system to allow dumping with external hydraulic source.
Engine and transmission sump oil level sensor protects the component and enhances the life.
Optional Oil Renewal System (ORS) helps reduce maintenance costs by routing used engine oil into the fuel system while automatically replenishing the engine with fresh oil from a make-up reservoir, extending service intervals and increasing machine availability.
