Clark S55L Specifications
The Clark S55L is a robust, rider-seated forklift built
to handle loads up to 5500 kg (12125 lb) with a 600 mm (24 in) load centre. As
part of Clark's S-Series, it is powered by a 3.8 L, 4-cylinder Kubota WG3800 LPG
engine, delivering 63.6 kW (85.3 hp) at 2200 rpm and incorporating advanced
emissions control technology with ECU-controlled map ignition and electronic
engine speed control.
The truck is distinguished by its sturdy fully welded heavy gauge frame,
reliable Clark nested I-beam mast construction, and a focus on operator safety
and comfort with features like an auto-engaging electric parking brake with
rollback protection on gradients and ramps, and hydrostatic power steering
eliminating steering kick-back.
Fitted with pneumatic tyres, it is well-suited for challenging outdoor terrains
and improved surfaces alike, with dual tyre options available for the drive axle
to improve traction and stability when transporting wide loads. With a laden
travel speed of 17.0 km/h (10.6 mph) and a gradeability of 26 percent, it
provides powerful and efficient performance in heavy industrial settings.
