Cat DP90 Specifications
The Caterpillar DP90 is a 20,000 lb capacity
diesel-powered forklift engineered for heavy-duty material handling applications
in industrial environments. Powered by a Mitsubishi 6D16 six-cylinder diesel
engine, this pneumatic tire model combines robust construction with
high-performance capabilities. The truck features a 3-speed automatic powershift
transmission for smooth operation and a hydraulic system delivering 2,610 psi
pressure for attachment compatibility.
With a turning radius of 151 in and
gradeability reaching 51 percent with load, the DP90 provides capable
performance in demanding applications including manufacturing
facilities, warehouse operations, and heavy industrial settings. The
design incorporates a heavy-duty steer axle for longevity, and
comprehensive service access simplifies maintenance procedures. The DP90
was manufactured by Caterpillar from 1996 to 2010, establishing a
reputation for reliability in lifting and material handling operations.
