Clark C25CL Specifications

Basic Information

The Clark C25CL is a robust, rider-seated forklift built to handle loads up to 2500 kg (5510 lb) with a 500 mm (20 in) load centre. As part of Clark's GEN2 C20-series, it is powered by a 2.4 L, 4-cylinder Hyundai Theta engine operating on LPG, delivering 52.5 kW (70.4 hp) at 2650 rpm. The truck is distinguished by its sturdy fully welded heavy gauge frame, reliable automatic powershift transmission, and a focus on operator safety and efficiency with features like hydrostatic power steering, a two-pedal inch-brake system, and high-visibility uprights.

Fitted with cushion tyres, it is well-suited for improved indoor surfaces in distribution, manufacturing, and warehousing applications. With a laden travel speed of 16.8 km/h (10.4 mph) and a right-angle stacking aisle width of 3666 mm (144.3 in), it provides efficient performance in material handling operations. The Clark C25CL incorporates advanced features including a full-flow reverse hydraulic filter system, priority steering distributor, load-sensitive control valve, and an ergonomic operator compartment with tilting steering column and full-suspension safety seat.
