Toyota 8FDU25 Specifications
The Toyota 8FDU25 is a 2.5-tonne (5,000 lb) capacity,
diesel-powered, seated rider forklift, engineered for reliable performance in
medium-duty material handling applications. As a core model in Toyota's
8-Series, this forklift integrates the advanced System of Active Stability (SAS)
to significantly enhance operator confidence and truck stability during complex
maneuvers in warehouses, distribution centers, and industrial environments.
Powered by the efficient Toyota 1ZS three-cylinder diesel engine, it delivers
responsive and reliable power while maintaining fuel efficiency. Its compact
design, tight turning radius, and efficient hydraulic system ensure productive
operation in confined spaces, while operator-centric features reduce fatigue and
promote safe, efficient work cycles.
The Toyota 8FDU25 is a counterbalanced pneumatic tire forklift truck designed
for versatility and safety. It operates on diesel fuel and is controlled by a
seated operator. Its rated load capacity is 2268 kg (5000 lb) at a 600 mm (24
in) load centre. The load distance from the drive axle centre to the fork face
measures 470 mm (18.5 in), and the truck has a wheelbase of 1651 mm (65 in).
Basic Technical Data: The main component of the Toyota
8FDU25 is the Toyota 1ZS engine, a three-cylinder diesel unit. It has a total
displacement of 1.8 L (110 cu.in). The engine is rated to produce 41 kW (55 hp)
at a rated speed of 2200 rpm. Maximum torque is 200 Nm (148 lb-ft) achieved at
1600 rpm. The engine features hydraulic valve lifters for quiet and reliable
operation. The liquid fuel tank capacity is 60 L (15.9 gal).
Lubrication and Cooling: The system is designed to support continuous operation
in demanding conditions. The engine employs a forced lubrication system to
protect internal components. Liquid cooling is maintained by a belt-driven
centrifugal water pump and a radiator with an integrated automatic transmission
oil cooler to maintain optimal operating temperatures.
Transmission: The 8FDU25 is equipped with a Toyota
Powershift transmission featuring electric shift control and an integrated oil
cooler. This transmission allows for smooth direction changes without clutching,
enhancing operator efficiency and reducing fatigue. It features one forward gear
and one reverse gear, providing simple and intuitive control.
Travel Speed: The forklift achieves a maximum travel speed of 19.0 km/h (11.8
mph) forward and reverse when fully laden. When unladen, the travel speed
increases to 19.5 km/h (12.1 mph) in both directions, ensuring consistent
maneuverability.
Axles and Brakes: The truck uses a drive axle configuration with two driven
wheels on the front. The service brake system is hydraulic, activated by a foot
pedal, providing reliable stopping power for both laden and unladen operations.
The electrical system operates at 12V. The system is
responsible for starting the diesel engine and powering all lights and operator
interface components. The system features moisture-resistant electrical
connectors for durability.
The Toyota 8FDU25 is fitted with pneumatic tyres,
designed for traction and comfort on various surfaces. It has four wheels in
total, with the front two being the driven wheels. The front tyre size is
7.00-12-12PR and the rear tyre size is 6.00-9-10PR. The front tread width
measures 960 mm (37.8 in), and the rear tread width is 965 mm (38.0 in). The
body and frame are constructed of welded steel for durability.
The Toyota 8FDU25 features load sensing hydrostatic power steering with
synchronized steering geometry. This system reduces the effort required by the
operator to turn the wheels, especially when the truck is stationary or under
load. The steering wheel is equipped with a knob for precise control during
maneuvering. The mast and fork carriage can tilt forward by 6 degrees and
backward by 11 degrees to facilitate load handling and secure transport.
The hydraulic system is a core component for lift and
tilt operations. It operates with an auxiliary function pressure relief setting
of 156 bar (2275 psi). The system's maximum rated pump flow is 72 L/min (19
gpm), which supplies the necessary volume for lift, tilt, and auxiliary
hydraulic functions. Integral and hang-on sideshifters, as well as integral
sideshifting fork positioners, are available as options.
The Toyota 8FDU25 is equipped with a standard 2-stage
limited free lift mast (V mast) with high visibility. With the mast fully
lowered, the height to the top of the mast is 2146 mm (84.5 in). The free lift,
which is the height the forks can rise before the mast itself begins to extend,
is 155 mm (6.1 in). The maximum fork height for the standard configuration is
3340 mm (131.5 in). The fork carriage width is 1016 mm (40 in).
Load Capacity: 5,000 lb (2,268 kg)
Load Centre: 24 in (600 mm)
The lift speed for the 2268 kg (5000 lb) rated load is
0.61 m/s (121 ft/min) when laden and 0.66 m/s (129 ft/min) when unladen.
Lowering speed is controlled and consistent at 0.50 m/s (98 ft/min) for both
laden and unladen conditions. The maximum drawbar pull, a measure of tractive
effort, is 1928 kg (4250 lb) for a laden truck and 875 kg (1930 lb) for an
unladen truck. The maximum gradeability is recorded as 29% for a laden truck and
20% for an unladen truck.
The length to the face of forks is 2640 mm (103.9 in).
The overall width of the truck is 1151 mm (45.3 in). The standard forks have
dimensions of 41 mm (1.6 in) thick, 127 mm (5 in) wide, and 1067 mm (42 in)
long. The height of the overhead guard is 2111 mm (83.1 in). Ground clearance
below the mast, when the truck is laden, is 94 mm (3.7 in). At the centre of the
wheelbase, ground clearance is 140 mm (5.5 in).
For maneuvering in aisles, the basic right-angle stacking aisle width, which
requires adding load length and clearance, is 2690 mm (105.9 in). The outer
turning radius is 2223 mm (87.5 in). The total operating weight of the truck is
3624 kg (7990 lb). When fully laden, the weight distribution on the front axle
is 5136 kg (11320 lb) and on the rear axle is 757 kg (1670 lb). When unladen,
these figures shift to 1379 kg (3040 lb) on the front and 2245 kg (4950 lb) on
the rear.
