Komatsu FD150E-7 Specifications
The Komatsu FD150E-7 is a high-capacity diesel-powered
forklift engineered for continuous heavy-duty operation in steel mills, large
fabrication plants, port terminals, mining supply yards, and precast concrete
industries.
With a rated lifting capacity of approximately
15,000 kg (33,000 lb) at a 600 mm (24 in) load center, the FD150E-7 is
designed for industries requiring stable, predictable load handling and
long-term structural durability.
This variant of the FD150E-7 is equipped with the Isuzu 6BG1-T
industrial turbocharged diesel engine. The 6BG1-T is a 6-cylinder,
6.5-liter heavy-duty powerplant widely known for its extreme
reliability, strong low-end torque, fuel economy, and service longevity.
The turbocharged design ensures responsive power for lifting heavy
loads, while the engine’s mechanical fuel injection, reinforced block
construction, and high-capacity cooling system make it ideal for harsh
working conditions.
Komatsu integrates this robust engine with a heavy-duty powershift
transmission, planetary reduction drive axle, and sealed wet-disc
braking system for long-life reliability. The reinforced welded-steel
chassis, wide mast stance, ergonomic operator station, and high-capacity
hydraulics ensure the FD150E-7 delivers dependable performance over
years of demanding industrial use.
