Tires
|
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.
|
|
Note (2)
|
Caterpillar recommends the customer evaluate all job conditions and consult the tire manufacturer for proper tire selection.

|
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.
