Standard Tire | 27.00R49 (E4) |
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 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 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. |
