Clark S55D Specifications
The Clark S55D 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
V3800-CR-TE5 diesel engine, delivering 55.4 kW (74.3 hp) at 2200 rpm and
incorporating advanced emissions control technology including a Diesel
Particulate Filter (DPF) and Diesel Oxidation Catalyst (DOC).
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 and hydrostatic power steering. 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 21.5 km/h
(13.4 mph) and a gradeability of 26 percent, it provides powerful and efficient
performance in heavy industrial settings.
