Note (1):
Productive capabilities of the 777 truck are such that, under certain job conditions, TKPH (TMPH) capabilities of standard or optional tires could be exceeded and, therefore, limit production.
Note (2):
Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection.
ROPS
ROPS Standards:
Rollover Protective Structure (ROPS) for cab offered by Caterpillar meets ISO 3471:2008 ROPS criteria.
FOPS Standards:
Falling Objects Protective Structure (FOPS) meets ISO 3449:2005 Level II FOPS criteria.
Sound
Sound Standards (1):
The operator Equivalent Sound Pressure Level (Leq) is 73 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 83 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.
