Cat 2C4000 Specifications
The Cat 2C4000 is a reliable Class IV internal
combustion cushion tire forklift built for demanding indoor applications
requiring 4,000 lb lifting capacity. Powered by a Nissan K25 engine with
gasoline or LPG fuel options, it provides responsive power delivery and
operational efficiency. Operators benefit from a well-designed compartment with
intuitive controls, good visibility, and a comfortable seat that reduces fatigue
during extended shifts. The single-speed powershift transmission ensures smooth
directional changes, while the hydrostatic power steering enhances
maneuverability in confined warehouse spaces.
