ROPS Standards (1)Rollover Protective Structure (ROPS) for cab offered by Caterpillar meets ISO 3471:2008 ROPS criteria.

FOPS StandardsFalling Objects Protective Structure (FOPS) meets ISO 3449:2005 Level II FOPS criteria.

Note (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 t

Note (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).

Note (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.

NoteOperator selectable coverage: 0.2-0.8 L/m² (4 kph - 40 kph) / 0.05-0.2 gal/ft² (3 mph - 25 mph). Coverage rates above 0.6 L/m² may not be available at higher speeds depending on head count and configuration.

Note (1)Opening is automatically controlled by the system to achieve AutoMode Coverage or Manual Mode Flow Rate.

Note (2)AutoMode Spray controls water coverage automatically to the number of heads being used and ground speed achieved.

Note (3)Manual Mode allows the operator to set a water flow rate that is constant regardless of ground speed.

Note (4)Spray Heads on competitive water distribution systems require tools and maintenance to change flow and spray pattern. Caterpillar is the only company to have variable active spray heads to regulate water spray.

Note (5)Water flow is continually adjusted during operation to conserve water and achieve desired coverage and flow rate
