Cat P3500 Specifications

Basic Information

The Cat P3500 is a capable Class V internal combustion pneumatic tire forklift built for general material handling requiring 3,500 lb lifting capacity. Powered by a Nissan K21 engine with gasoline or LPG fuel options, it provides adequate power delivery and operational efficiency. Operators benefit from a functional compartment with intuitive controls, good visibility through the mast area, and a comfortable seat suitable for various shift lengths. The single-speed powershift transmission ensures smooth directional changes, while the hydrostatic power steering and 78 in (1,975 mm) turning radius enhance maneuverability in confined spaces. The pneumatic tires provide traction and stability on uneven surfaces, making this model adaptable to varied working environments.
