Sound Standards (1)The operator sound pressure level measured according to work cycle procedures specified in ISO 6394:2008 and 6396:2008 is 76 dB(A) for cab offered by Caterpillar when properly installed and maintained and tested with doors and windows closed.
Sound Standards (2)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.
Note (1)Refer to the Cat Mining Truck 10/10/20 Payload Policy for maximum gross machine weight limitations.
NoteProductive capabilities of the 797F are such that, under certain job conditions, TKPH (TMPH) capabilities of standard tires could be exceeded and, therefore, limit production.
Note (1)Power ratings apply at 1,750 rpm when tested under the specific conditions for the specified standard.
Note (2)Body weight varies depending on body and liner configuration. Weight range for known applications.
Note (2)Ratings based on SAE J1995 standard air conditions of 25° C (77° F) and 99 kPa (29.32 Hg) barometer. Power based on fuel having API gravity of 35 at 16° C (69° F) and an LHV of 42 780 kJ/kg (18,390 Btu/lb) when engine is used at 30° C (38° F).
Note (3)Chassis weight with 100 percent fuel, hoist, body mounting group, rims and tires.
Note (3)No low altitude arrangement (LAA) engine derating required up to 2134 m (7,000 ft) altitude.
Note (4)No high altitude arrangement (HAA) engine derating required up to 4877 m (16,000 ft) altitude.
