Komatsu FD25T-16 Specifications
The Komatsu FD25T-16 is a 2.5-ton (2,500 kg / 5,500 lb)
diesel-powered pneumatic-tire forklift designed for medium-to-heavy industrial
operations requiring excellent outdoor traction, continuous duty performance,
high torque availability, and robust structural reliability.
As a member of the Komatsu 16 Series, the
FD25T-16 benefits from an upgraded chassis, improved Cooling System
efficiency, increased hydraulic responsiveness, improved operator
visibility, and enhanced driveline durability. The forklift is powered
by the Komatsu 4D94E engine, a 3.3-liter, 4-cylinder diesel engine known
for long service life, strong low-end torque, low fuel consumption, and
dependable mechanical injection.
This engine pairs with Komatsu’s
torque-converter powershift transmission and high-output hydraulic
system for efficient lifting and transport performance in demanding
industrial settings including Construction material depots, metal and
fabrication shops, outdoor logistics areas, and general industrial
yards.
