Jallad | 938K Wheel Loader

938K

The CatÂ® 938K Small Wheel Loader sets the standard for productivity, fuel efficiency and operator comfort. The improved optimized Z-bar loader linkage delivers the quick loading performance of a traditional Z-bar with the parallelism and load handling capability of a tool carrier. A high torque, low speed C7.1 engine works in concert with an intelligent hystat power train to deliver fuel efficiency as standard.

Note (3)

The declared exterior sound power level is 104 dB(A) when the value is measured according to the dynamic test procedures and the conditions that are specified in “ISO 6395:2008.”

Note (1)

The declared dynamic operator sound pressure level is 72 dB(A) when “ISO 6396:2008” is used to measure the value for an enclosed cab.

Note (2)

The measurement was conducted at 70% of the maximum engine cooling fan speed, with the cab doors and cab windows closed. The cab was properly installed and maintained. The sound level may vary at different engine cooling fan speeds.
