Toyota 8FD40U Specifications
The Toyota 8FD40U is a 4.0-tonne (8,818 lb) capacity,
diesel-powered, seated rider forklift, engineered for robust performance in
medium to heavy-duty material handling applications. As part of Toyota's
8-Series, this model integrates the advanced System of Active Stability (SAS) to
significantly enhance operator confidence and truck stability during demanding
maneuvers.
Powered by the efficient Toyota 1KD common-rail diesel engine, it delivers
reliable power while meeting Tier 4 Final emission standards. Its durable
construction, combined with a high-output hydraulic system and operator-focused
features, ensures productive, safe, and comfortable operation throughout long
shifts in warehouses, distribution centers, and industrial environments.
The Toyota 8FD40U is a counterbalanced forklift truck designed for high-capacity
versatility and safety. It operates on diesel fuel and is controlled by a seated
operator. Its rated load capacity is 4000 kg (8818 lb) at a 600 mm (24 in) load
centre. The distance from the drive axle centre to the fork face measures 505 mm
(19.9 in), and the truck has a wheelbase of 1900 mm (74.8 in). The total weight
of the truck when unladen is 6150 kg (13560 lb).
Basic Technical Data: The main component of the Toyota
8FD40U is the Toyota 1KD engine, a four-cylinder diesel unit with a double
overhead camshaft design. It has a total displacement of 2982 cc (182 cu.in).
The engine is rated to produce 55 kW (74 hp) at a rated speed of 2200 rpm.
Maximum torque is 300 Nm (220 lb-ft) achieved at 1500 rpm. This engine meets
Tier 4 Final emission standards, utilizing a Diesel Oxidation Catalyst. The fuel
tank capacity is 90 L (24 gal).
Lubrication and Cooling: The engine is equipped with a full-flow lubrication
system with a spin-on oil filter. Liquid cooling is maintained by a belt-driven
centrifugal water pump and a radiator with an automatic transmission oil cooler
integrated into the system.
Transmission: The 8FD40U 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 22.0 km/h (13.7
mph) when fully laden and 24.0 km/h (15.0 mph) when unladen. The reverse speeds
are identical to the forward speeds, ensuring consistent maneuverability in both
directions.
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.
A hand-operated parking brake is also provided.
The electrical system operates at 12 V. Battery
capacity is rated at 48 Ah at a 5-hour discharge rate. The system is responsible
for starting the diesel engine and powering all lights and operator interface
components.
The Toyota 8FD40U 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
250-15-18PR, and the rear tyre size is 7.00-12-12PR. The front tread width
measures 1115 mm (43.9 in), and the rear tread width is 1100 mm (43.3 in).
The Toyota 8FD40U features full hydraulic power steering with a steering
cylinder. This system reduces the effort required by the operator to turn the
wheels, especially when the truck is stationary or under load. The mast and fork
carriage can tilt forward by 6 degrees and backward by 12 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 hydraulic operating pressure of
185 kg/cm2 (2630 psi). The system's rated pump flow is 128 L/min (33.8 gpm),
which supplies the necessary volume for lift, tilt, and auxiliary hydraulic
functions. Hydraulic valve lifters are incorporated into the system.
The Toyota 8FD40U is equipped with a standard two-stage
mast with high visibility. With the mast fully lowered, the height to the top of
the mast is 2110 mm (83 in). The free lift, which is the height the forks can
rise before the mast itself begins to extend, is 110 mm (4.3 in). The maximum
lift height for the standard configuration is 3050 mm (120 in), at which point
the mast extends to a total height of 4270 mm (168.1 in) including the load
backrest.
Load Capacity: 8,818 lb (4,000 kg)
Load Centre: 24 in (600 mm)
The lift speed for the 4000 kg (8818 lb) rated load is
0.525 m/s (103 ft/min) when laden and 0.55 m/s (108 ft/min) when unladen.
Lowering speed is controlled at 0.53 m/s (104 ft/min) for laden and 0.48 m/s (94
ft/min) for unladen conditions. The maximum drawbar pull, a measure of tractive
effort, is 3700 kg (8157 lb) for a laden truck and 1410 kg (3120 lb) for an
unladen truck. The maximum gradeability is recorded as 39%.
The length to the face of forks is 2980 mm (117.3 in).
The overall width of the truck is 1350 mm (53.1 in). The standard forks have
dimensions of 50 mm (2 in) thick, 150 mm (6 in) wide, and 1070 mm (42 in) long.
The maximum fork spread is 1170 mm (46.1 in) and the minimum is 300 mm (11.8
in).
The height of the overhead guard is 2210 mm (87 in). The seat height and
coupling height are not detailed in the provided source material. Ground
clearance below the mast, when the truck is laden, is 120 mm (4.7 in). At the
centre of the wheelbase, ground clearance is 200 mm (7.9 in).
For maneuvering in aisles, the basic right-angle stacking aisle width, which
requires adding load length and clearance, is 3170 mm (124.5 in). The outer
turning radius is 2660 mm (104.5 in). The total operating weight of the truck is
6150 kg (13560 lb).
