Komatsu FD135-8 Specifications
The Komatsu FD135-8 is a heavy-duty diesel
pneumatic-tire forklift engineered for extremely demanding industrial operations
requiring reliable lifting of 13.5-ton (30,000 lb class) loads. Positioned above
the FD115-8 and FD100-8 models, the FD135-8 represents one of Komatsu’s most
capable high-capacity forklifts for continuous-duty industrial applications. It
is used in steel mills, port and marine terminals, fabrication yards, mining
support facilities, precast concrete production, heavy manufacturing, and large
logistics yards.
The FD135-8 is powered by Komatsu’s SAA6D107E-1 diesel engine - a 6.69-liter
turbocharged and aftercooled inline-six designed for high torque at low RPM. The
engine integrates an electronic common-rail fuel system, robust block and
crankshaft construction, a heavy cooling package, and an industrial lubrication
system. Together, these features ensure smooth and efficient heavy-duty
operation with long component life, low vibration, precise fuel control, and
reliable performance in harsh environments.
Komatsu equips the FD135-8 with a heavy-duty powershift transmission, planetary
reduction drive axle, sealed wet-disc brakes, oversized pneumatic tires, and a
high-capacity hydraulic lift and tilt system. The reinforced steel chassis, wide
mast stance, and large counterweight provide outstanding stability during
high-elevation lifting.
Operator comfort and control are enhanced
through an ergonomic compartment, wide visibility mast design, and
intuitive control layout. The machine is designed for minimal downtime,
long service intervals, and high productivity under severe working
conditions.
