CAT 775®

OFF-HIGHWAY TRUCK BARE CHASSIS

Caterpillar offers off-highway truck bare chassis designed for specialty machines in a variety of applications —including water trucks, tow tractors, and fuel / lube trucks. When configured as a water truck, the tank capacity is
11,000 gallons (41 500 liters). These partial machine configurations allow construction, quarry, and mining customers topurchase complete solutions from our global Cat ® dealer network — with support every step of the way.

PROVEN CAT TRUCK PLATFORM

SAFETY BUILT IN

Cat trucks are built for durability, reliability, andefficiency to deliver the performance you need insome of the toughest applications around the world.

As we design a truck, we take the safety of the operator
and personnel working on the ground very seriously.
Ground level and platform accessible daily check points.
Excellent visibility. Solid, stable walking/working
platforms with good traction, material shedding,handrails. And the new Traction Control System,
returns the truck to solid footing sooner.

APPLICATION-SPECIFICCAB & ROPS CERTIFICATIONCat Off-Highway Truck Bare Chassis ROPS is certified
to ISO 3471 Tractor criteria, to provide a higher levelof protection for towing applications.

OPERATOR EXPERIENCE
A truck is only as productive as its operator — so
we've updated the 775 with some key features to help
old and new operators be comfortable and confident
while operating the truck. Convenient automatic
temperature control and powered left side window.
Low-effort access getting in and out of the cab with
ample stand up room. Cat Comfort Seat with airsuspension and excellent adjustability.

FUEL SAVINGS

Fuel savings are achieved by reducing power
between 0.15 to 15% during all phases of operation.
Part throttle shifting has the benefit of saving fuel –it no longer needs to apply fuel towards overcoming
lost momentum between shifts.

SIMPLE SERVICEThis truck is designed to provide operators andtechnicians with easy access to common service
points like engine lockout, machine system lockout,
fluid level sight gauges, grease fittings, and access tothe engine for regularly scheduled maintenance.

Operating Weights – with Hoist Cylinders (LRC)• Productive capabilities of the 775G truck are such that, under certain

job conditions, TKPH (TMPH) capabilities of standard or optional tires
could be exceeded and, therefore, limit production.
• Caterpillar recommends the customer evaluates all job conditions
and consults the tire manufacturer for proper tire selection.
