Cat DP45K Specifications
The Caterpillar DP45K is a 4,500 kg capacity
diesel-powered forklift engineered for demanding material handling applications
in industrial environments. Powered by a Mitsubishi S6S six-cylinder diesel
engine, this pneumatic tire model combines robust construction with reliable
performance characteristics. The truck features a powershift transmission for
smooth operation and a hydraulic system delivering 191 bar pressure for
attachment compatibility.
With a turning radius of 2,830 mm and
gradeability reaching 24 percent without load, the DP45K provides
capable performance in warehouses, construction sites, and logistics
operations. The design incorporates a heavy-duty steer axle for
longevity, while mast and carriage load rollers receive permanent
lubrication to reduce maintenance requirements. Rapid access to
transmission components simplifies servicing, and axle lubrication
points are positioned for easy reach. The DP45K was manufactured by
Caterpillar from 1996 to 2014, establishing a reputation for reliability
in lifting and material handling operations.
