Toyota 52-8FDF25 Specifications
The Toyota 52-8FDF25 is a modern, mid-capacity
diesel-powered forklift belonging to Toyota’s 8-Series diesel line, designed for
highly demanding industrial applications requiring consistent performance,
rugged reliability, and strong load-handling capabilities. With a nominal
lifting capacity of 2,500 kilograms (5,500 pounds), the 52-8FDF25 meets the
needs of manufacturing plants, steel and metal-processing facilities,
distribution warehouses, lumber yards, ports, and heavy logistics environments.
Pneumatic tires allow dependable traction on
uneven outdoor surfaces, and Toyota’s advanced System of Active
Stability (SAS) enhances operator safety by continuously monitoring
steering angle, mast position, and load movement.
Powered by Toyota’s highly efficient industrial diesel engines—such as
the 1DZ-II or 1ZS diesel—the 52-8FDF25 delivers powerful low-end torque
with excellent fuel economy. Operators benefit from a low-vibration cab
design, ergonomic lever layout, and generous visibility through the
mast.
Maintenance teams appreciate the wide-opening
engine hood, simplified servicing layout, long-life components, and
rugged drivetrain. The 52-8FDF25 has become a preferred forklift for
industrial fleets due to its exceptional service life, predictable
handling, efficient operating cost profile, and dependable performance
across a wide range of working conditions.
The Toyota 52-8FDF25 is equipped with either the Toyota
1DZ-II or 1ZS diesel engine, depending on production year and emissions
requirements. These engines are purpose-built industrial diesel units designed
for continuous operation under high load, offering excellent low-RPM torque,
long durability, and low specific fuel consumption.
