Toyota 8FDU20 Specifications
The Toyota 8FDU20 is a diesel-powered, counterbalanced
forklift truck produced from 2013 through 2025. This rider-seated model is
engineered for demanding material handling tasks requiring a rated load capacity
of 4000 lb or 1.8 t. The machine is powered by the Toyota 1ZS engine, a
three-cylinder diesel unit with a displacement of 1.8 liters.
The 8-Series diesel forklifts offer outstanding comfort and excellent
operability with high onboard technology contributing to a safe workspace. The
forklift includes Toyota's System of Active Stability (SAS) with Active Control
Rear Stabilizer and Active Mast Control, the Operator Presence Sensing System
(OPSS), bolt-on overhead guard, key lowering interlock, and neutral engine start
safety switch.
The machine features a welded steel body and frame construction, load sensing
hydrostatic power steering, automatic transmission with oil cooler, hydraulic
valve lifters, and electric shift control. Available attachments include
integral and hang-on sideshifters and integral sideshifting fork positioners.
The Toyota 8FDU20 is a four-wheeled forklift with a load capacity of 4000 lb or
1814 kg at a 24 in or 600 mm load centre. The nominal load at centre of gravity
is 1.8 t. Its design prioritises stability and manoeuvrability in demanding
environments. The machine is fitted with pneumatic tyres as standard, suitable
for indoor and outdoor use on improved surfaces. The transmission type is
Powershift with one forward and one reverse gear.
Basic Technical Data: The forklift is powered by the
Toyota 1ZS engine, a three-cylinder diesel unit. With a displacement of 110
cu.in or 1.8 L, this engine produces 55 hp or 41 kW of power at a rated speed of
2200 rpm. The engine delivers peak torque of 148 lb-ft or 201 Nm at 1600 rpm.
The engine meets Tier 4f emission standards. The engine is equipped with
hydraulic valve lifters. The liquid fuel tank capacity is 15.9 US gal or 60 L.
Lubrication: The engine lubrication system is a forced-feed type, employing a
gear pump to circulate oil throughout the engine block and cylinder head,
ensuring all moving components are adequately lubricated for reduced friction
and prolonged engine life. The system includes a full-flow oil filter to remove
contaminants.
Cooling: Engine temperature is regulated by a liquid cooling system. This system
comprises a radiator, a water pump, a thermostat, and a cooling fan. The water
pump circulates coolant through the engine jackets to absorb heat, which is then
dissipated as it passes through the radiator core.
Transmission: The Toyota 8FDU20 is equipped with a
Powershift transmission featuring one forward and one reverse gear. This
transmission allows for smooth direction changes without the need for a clutch
pedal, reducing operator fatigue during frequent shuttling. The system includes
an integral oil cooler to maintain proper operating temperatures. Electric shift
control provides precise and reliable gear engagement.
Travel Speed: The forklift achieves a laden travel speed of 11.8 mph or 19.0
km/h forward and reverse. The unladen travel speed is 12.1 mph or 19.5 km/h
forward and reverse.
Axles: The front axle is a rigid, drive axle that carries the majority of the
load, while the rear axle is a steer axle. The rear axle is designed to
oscillate, allowing all wheels to maintain ground contact on uneven surfaces,
which is crucial for stability.
Brakes: The service brake system is hydraulic, providing reliable and controlled
stopping power. This system uses hydraulic pressure to apply the brakes,
offering a consistent pedal feel and effective deceleration. The parking brake
is mechanical, hand-operated, engaging mechanically to secure the machine when
parked.
The electrical system operates on a 12 V architecture.
It includes a maintenance-free battery with sealed construction and
moisture-resistant electric connectors for enhanced durability in outdoor
environments. The system encompasses a starter, an alternator with built-in
regulator to charge the battery while the engine runs, and a comprehensive
wiring harness connecting all electrical components, including the SAS and OPSS
safety systems. The dash-mounted instrument display provides gauges and warning
indicators.
Wheel Drive: The Toyota 8FDU20 features a 2-wheel drive
configuration, with the front wheels providing the tractive effort (2x driven
wheels).
Wheels: The forklift uses a 2x2 wheel configuration, meaning two wheels on the
front axle and two on the rear. The front wheels are the driven wheels. The
track width, the distance between the centre lines of the left and right wheels,
is 1150 mm or 45.3 in.
Tires: This model is fitted with pneumatic tyres as standard. The tyre size for
the front is 7.00-12-12PR. The tyre size for the rear is 6.00-9-10PR. These
tyres provide cushioning and traction for outdoor applications. The machine
features wide tread and plate-iron front fenders for durability.
Steering: The steering system is load sensing hydrostatic power steering, making
manoeuvring the truck effortless for the operator. The steering system includes
synchronized steering and a small-diameter 11.8-inch two-spoke steering wheel
with a knob for enhanced control.
The steering column allows seamless adjustment
for different operator preferences. Load Sensing Power Steering (LSPS)
adjusts the amount of power-steering fluid according to the load burden
on the rear axle, reducing energy loss and helping to enhance fuel
economy. The system includes a hydraulic accumulator for consistent
steering performance.
The hydraulic system is designed for efficient lifting
and tilting operations with fully oil-charged lift cylinders. It operates at an
auxiliary function pressure relief of 2275 psi or 157 bar for powering
attachments. The system pump delivers a rated flow of 19 gpm or 72 L/min maximum
for auxiliary functions.
This system powers the lift cylinders for
raising the mast and the tilt cylinders for mast forward and backward
movement. Cowl-mounted hydraulic control levers with rubber boot covers
provide convenient operator access. Auxiliary hydraulic functions
support additional attachments such as integral and hang-on sideshifters
and integral sideshifting fork positioners. The system includes tilt
cylinder boots for protection.
The Toyota 8FDU20 can be equipped with various mast
types including 2-stage limited free lift mast (V) and 3-stage configurations.
Specifications for a standard mast include a maximum fork height of 131.5 in or
3340 mm. The mast lowered height is 84.5 in or 2146 mm. The mast has a free lift
of 6.1 in or 155 mm, allowing the forks to be raised to this height without
increasing the mast's overall height.
Alternative mast configurations offer maximum lift heights up to 187 in or 4750
mm. The load distance from the centreline of the front axle to the front face of
forks is 18.5 in or 470 mm. The fork carriage width is 40 in or 1016 mm. The
mast and fork carriage can tilt forward by 6 degrees and backward by 11 degrees
to facilitate load handling and secure transport.
Load Capacity: 4,000 lb (1,814 kg)
Load Centre: 24 in (600 mm)
The lift speed with a load is 121 fpm or 0.615 m/s, and
without a load, it is 129 fpm or 0.655 m/s. The lowering speed with a load is 98
fpm or 0.500 m/s, and without a load, it is 98 fpm or 0.500 m/s. The maximum
drawbar pull, or the pulling force, is 4250 lb or 1930 kg when laden and 2040 lb
or 925 kg when unladen. Its gradeability, the ability to ascend a slope with a
load, is 39%. The maximum gradeability without load is 23%.
The overall length of the truck, including the forks,
is 3695 mm or 145.5 in, while the length to the face of the forks is 101.4 in or
2575 mm. The overall width is 45.3 in or 1150 mm. The height of the overhead
guard is 83.1 in or 2110 mm. The standard fork dimensions are 1.6 in or 40 mm
thick, 5 in or 125 mm wide, and 42 in or 1067 mm long. Alternative fork lengths
of 48 in are available depending on configuration. The wheelbase measures 65 in
or 1651 mm. The tread width is 37.8 in or 960 mm for the front and 38 in or 965
mm for the rear.
Ground clearance minimum with load is 3.7 in or 94 mm. Ground clearance at the
centre of wheelbase is 5.5 in or 140 mm. The basic right-angle stacking aisle
width, adding load length and clearance, is 103.2 in or 2621 mm. The outer
turning radius is 84.7 in or 2150 mm. The gross weight (empty) of the machine is
7230 lb or 3280 kg. Weight distribution with full load places 9810 lb or 4450 kg
on the front axle and 1420 lb or 644 kg on the rear axle. Without load, weight
distribution shifts to 3180 lb or 1442 kg on the front axle and 4050 lb or 1837
kg on the rear axle.
