| FOPS Standards |
Falling Objects Protective Structure (FOPS) meets ISO 3449:2005 Level II FOPS criteria. |
| 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. |

1200 r/min (1200 r/min) |
| ROPS Standards |
Rollover Protective Structure (ROPS) for cab offered by Caterpillar meets ISO 3471:2008 ROPS criteria. |
| 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. |
