Standards
Sound The declared dynamic operator sound pressure level is 85 dB(A) when "ISO 6396:2008" is used to measure the value for an enclosed cab. The measurement was conducted at 100% of the maximum engine cooling fan speed. The cab was properly installed and maintained. The measurement was conducted with the cab doors and the cab windows closed.
ROPS ROPS (Rollover Protective Structure) offered by Caterpillar for the machine meets ROPS criteria ISO 3471:2008.
Note Hearing protection may be needed when the machine is operated with an open operator station for extended periods or in a noisy environment. Hearing protection may be needed when the machine is operated with a cab that is not properly maintained or when the doors and windows are open for extended periods or in a noisy environment.
FOPS FOPS (Falling Object Protective Structure) meets ISO 3449:2005 Level II.
Brakes Brakes meet the standard ISO 10265.
