Clark GTS25L Specifications
The Clark GTS25L 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 GTS Series (20-33), it is powered by a 2.4 L, 4-cylinder
Mitsubishi 4G64 LPG engine with a PSI (Power Systems Incorporated) fuel system,
delivering 51.6 kW (69 hp) at 2650 rpm. The truck is distinguished by its sturdy
fully welded heavy gauge frame, reliable split transmission, and a focus on
operator safety and efficiency with features like hydrostatic power steering
that eliminates steering kick-back, maintenance-free wet disc brakes with a
3-year warranty, and a nested I-beam mast design for enhanced stability.
Fitted with pneumatic tyres, it is well-suited for both indoor and outdoor
improved surfaces, with optional dual tyre configurations for added stability.
With a laden travel speed of 16.9 km/h (10.5 mph) and a gradeability of 26-30
percent, it provides efficient performance in distribution, manufacturing, and
warehousing applications. The Clark GTS25L incorporates advanced features
including a full-flow reverse hydraulic filter system, priority steering
distributor, load-sensitive control valve, safety valve for uncontrolled
lowering prevention, and an ergonomic operator compartment with tilting steering
column and full-suspension seat.
