775 Off-Highway Truck
Having a solid track record in the quarry and aggregates industry, Cat’s 775 has been designed and manufactured using the latest quality control technologies—both virtually and hands on—to ensure your Off-Highway Truck is ready to do work. Built with a Cat C27 diesel engine, the 775 has improved fuel efficiency and delivers an additional 5% horsepower. Our 775 is a great pass match for the Cat 988K or 990K Wheel Loader, too. By having the Cat Off-Highway Trucks in your haul fleets, you can be more productive, spend less time on maintenance, and support the environment with new levels of eco performance. Which ultimately allows you to make a positive impact within your business and community every day.

Tires
Note (2)
Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection.
Note (1)
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.
Standard Tire
24.00R35 (E4)
ROPS
FOPS Standards
Falling Objects Protective Structure (FOPS) meets ISO 3449:2005 Level II FOPS criteria.
ROPS Standards
Rollover Protective Structure (ROPS) for cab offered by Caterpillar meets ISO 3471:2008 ROPS criteria.
Sound
Sound Standards (1)
The operator Equivalent Sound Pressure Level (Leq) is 76 dB(A) when SAE J1166 FEB2008 is used to measure the value for an enclosed cab. This is a work cycle sound exposure level. The cab was properly installed and maintained. The test was conducted with the cab doors and the cab windows closed.
Sound Standards (2)
The exterior sound pressure level for the standard machine measured at a distance of 15 m (49 ft) according to the test procedures specified in SAE J88:2008, mid‑gear moving operation is 86 dB(A).
Sound Standards (3)
Hearing protection may be needed when operating with an open operator station and cab (when not properly maintained or doors/windows open) for extended periods or in a noisy environment.
