Caterpillar (CAT) 938H Specifications

Discontinued in 2012, the Caterpillar 938H wheel loader features the 180-horsepower Cat C6.6 ACERT diesel and new differential lock system, load sensing hydraulics and increased lift and tilt forces. Cat’s Fusion Wheel Loader Coupler System moves the center of gravity closer to the machine, while enabling quick exchanges of buckets and a range of work tools. The in-cab Messenger display provides real-time performance and diagnostic data. Cat Product Link, providing two-way information flow between the machine and Caterpillar dealer and to the owner’s desktop computer, is standard on the new loaders.
