CATERPILLAR 777G PDF

Rated payload for the new G is The design of the G, which replaces the F, focuses on fuel efficiency, enhanced visibility, and operator comfort, convenience, and safety. The engine delivers 1, gross horsepower kW and incorporates a number of fuel-conservation features. Auto Neutral Idle allows the G transmission to intermittently shift to neutral when the truck is idling in a forward gear to avoid stalling the torque converter and increasing engine speed. Engine Idle Shutdown, an operator-selected feature, stops the engine when the truck idles in park for more than a preset interval.

Rated payload for the new G is The design of the G, which replaces the F, focuses on fuel efficiency, enhanced visibility, and operator comfort, convenience, and safety. The engine delivers 1, gross horsepower kW and incorporates a number of fuel-conservation features. Auto Neutral Idle allows the G transmission to intermittently shift to neutral when the truck is idling in a forward gear to avoid stalling the torque converter and increasing engine speed.

Engine Idle Shutdown, an operator-selected feature, stops the engine when the truck idles in park for more than a preset interval. Speed Limiting provides an alternative to gear-limiting the G by allowing the truck to travel at a more fuel-efficient engine speed and in a more efficient transmission gear.

Standard Economy saves fuel by reducing engine power by 0. Adaptive Economy requires a production baseline for the site using the Advisor display, and then, as the truck travels the haul cycle, the system automatically evaluates the power rating needed to meet baseline requirements. Full power is applied when needed, and reduced power is applied when appropriate. Operator environment and safety The G features a redesigned cab, easier to enter and exit, and having a new operator seat on the left and a more comfortable trainer seat on the right.

A new console with an integrated hoist-and-shift lever enhances convenience, as does more interior space for storage. Laminated glass is used in the front and left windows, and emergency egress is provided via a right-side hinged window. A ground-level engine-shutdown switch is readily accessible, and a secondary steering system is provided in the event of the primary steering system failure.

Powerful wet-disc brakes are used at all four corners and provide parking brake and slope-holding capability. Brake life can be extended with an available engine brake, and a brake-wear indicator facilitates timely maintenance. Box-section castings are used strategically in high-stress areas, a new front frame design increases the approach angle on ramps and grades, and a heavy-duty rear axle housing axle allows increased lubrication and filtration of critical components.

The Dual Slope Body, designed for optimum material retention on haul roads with steep slopes, carries material low and centered for stability. Heaped capacity is Two side-board sizes increase capacity for lighter weight materials. The X body has a flat floor and facilitates metering material into a crusher; standard heaped capacity is Rubber or steel liners are available for both bodies.

Light-material bodies provide capacities to cubic yards m3. Hydraulic-oil filter life is 1, hours under normal conditions. Fluid-fill and extraction points are grouped for convenience, and all check points are located at ground level and lighted for night access. A master disconnect switch, engine lock-out switch, and hydraulic lockout switch provide a convenient method when servicing the G.
