Cat GP40KL Specifications
The Cat GP40KL is a 4,000 kg (8,820 lb) capacity
pneumatic tire forklift powered by an LPG engine. This four-wheel, sit-down
counterbalanced truck is engineered for demanding material handling tasks in
industrial environments, including manufacturing, logistics, and construction
supply. Power is provided by a Nissan TB45 engine, generating 72 kW (97 hp),
mated to a single-speed powershift transmission with hydraulic accumulator. The
truck enables travel speeds up to 19.5 km/h (12.1 mph) and uniform lifting
speeds of 4.40 m/s (866 fpm) both loaded and empty. Key features include
hydrostatic power steering, a heavy-duty cast drive axle, and a standard
two-stage mast providing 3,300 mm (130 in) of maximum fork height. The GP40KL
incorporates an Engine Protection System and is designed for reliable
performance with pneumatic tires suited for varied surface conditions.
