Toyota 8FGU20 Specifications
The Toyota 8FGU20 represents a well-engineered solution
in the 4000 lb capacity forklift class, offering a balanced combination of
power, efficiency, and maneuverability. Powered by the Toyota 4Y-ECS electronic
fuel injection engine, this model delivers reliable performance with 51 hp while
maintaining fuel efficiency suitable for both indoor and outdoor applications.
Its compact design, combined with a tight turning radius of 84.7 in (2.2 m),
allows for excellent maneuverability in congested warehouse aisles and tight
spaces.
The 8FGU20 is equipped with pneumatic tires, providing enhanced stability and
traction on uneven surfaces. Operators benefit from ergonomic features including
load-sensing hydrostatic power steering, an adjustable full-suspension seat, and
fingertip hydraulic controls that reduce fatigue during extended shifts. As an
8-Series model, it incorporates Toyota's System of Active Stability (SAS) and
Operator Presence Sensing System (OPSS) for enhanced operational safety.
The Toyota 8FGU20 is a rider-seated forklift powered by a gasoline or LPG engine
with electronic fuel injection. It has a load capacity of 4000 lb at a 24 in
load centre, equivalent to 1814 kg at a 600 mm load centre. The distance from
the drive axle centre to the fork face is 18.5 in or 470 mm.
The Toyota 8FGU20 is powered by the Toyota 4Y-ECS
engine, a sophisticated four-cylinder power unit known for its reliability, fuel
efficiency, and advanced electronic controls.
Basic Technical Data: The engine is a four-cylinder gasoline or LPG engine with
an Overhead Valve (OHV) design and electronic fuel injection. It has a
displacement of 2.2 l or 136 cu in. It produces a rated power of 51 hp at 2570
rpm, equivalent to 38 kW at 2570 rpm. The engine delivers rated torque of 118
lb-ft at 2100 rpm, equivalent to 160 Nm at 2100 rpm. The liquid fuel tank
capacity is 15.9 US gal or 60 l.
Lubrication: The engine employs a forced lubrication system with hydraulic valve
lifters for quiet operation and reduced maintenance. Routine maintenance,
including oil and filter changes, is mandated at specific hourly intervals as
outlined in the periodic maintenance schedule to ensure longevity and
performance. The system uses a specific grade of engine oil, the capacity of
which is detailed in the service refill capacities section.
Cooling: Engine temperature is regulated by a pressurized liquid cooling system
with a high-capacity radiator and fan shroud for optimal heat dissipation.
Regular inspection of coolant levels and condition, as well as monitoring the
radiator, water pump, and hoses for wear and debris, is part of standard
preventative maintenance.
Transmission: The 8FGU20 is equipped with a powershift
transmission featuring one forward and one reverse gear. This transmission
allows for direction changes with a simple flip of a lever, without the need for
clutching, enhancing operator efficiency and reducing fatigue. The transmission
includes an oil cooler for extended durability and electric shift control for
precise engagement.
Travel Speed: This forklift achieves a laden travel speed of 10.9 mph or 17.5
km/h in both forward and reverse. When unladen, the travel speed increases to
11.2 mph or 18.0 km/h.
Axles: The front axle is a drive axle with 2 driven wheels, designed to bear the
majority of the load during lifting operations. The rear axle is a steer axle
with 2 wheels, which pivots to maintain ground contact on uneven surfaces. Both
are robustly constructed to handle the stresses of daily use.
Brakes: Service braking is handled by a hydraulic braking system, providing
reliable and progressive deceleration essential for safety when handling loads.
The brakes are self-adjusting for consistent performance and reduced
maintenance. The parking brake is hand-operated.
The electrical system operates at a standard 12 volts,
powering the starter motor, lights, and electronic control units. The system
includes a Control Area Network (CAN-bus) for enhanced diagnostics and
monitoring. An LCD multi-function display on the dash provides operational data
including hour meters, engine coolant temperature, fuel level, and warning
indicators, with QR code output for diagnostic access. The system features
moisture-resistant electrical connectors for reliable operation in various
environments.
The chassis is a heavy-duty, welded steel structure
that supports all major components: the engine, drivetrain, counterweight, and
mast. The frame includes stamped steel side panels and front fenders for
durability.
The truck is fitted with pneumatic tires, which provide enhanced stability and
traction on uneven surfaces common in outdoor applications. The front tires are
size 7.00-12-12PR, and the rear tires are size 6.00-9-10PR. The wheel
configuration features 2 driven wheels at the front and 2 steer wheels at the
rear. The standard tread width is 37.8 in or 960 mm at the front and 38.0 in or
965 mm at the rear.
The 8FGU20 features load-sensing hydrostatic power steering, which significantly
reduces the effort required to turn the wheel, especially when the truck is
stationary or moving slowly under load. This system enhances maneuverability and
reduces operator fatigue. The steering column is tilt-adjustable for operator
comfort. Synchronized steering is available as an option, and a steering wheel
with knob is also optional.
The hydraulic system powers the lifting, tilting, and
auxiliary functions such as sideshift and fork positioner. The system is
designed for precise load control and efficient operation. It includes a
hydraulic pump, control valves, lift cylinders, and tilt cylinders. The
auxiliary function pressure relief is set at 2275 psi or 157 bar. The rated pump
flow is 20 gpm or 76 lpm. The system features cowl-mounted hydraulic control
levers with rubber boot covers for protection. Integral and hang-on sideshifters
are available options.
The forklift can be equipped with various mast types,
including 2-stage limited free lift mast (V) and 3-stage masts for higher lift
heights. The standard mast configuration with V mast has a lowered height of
84.5 in or 2146 mm. It provides a free lift of 6.1 in or 155 mm, enabling
lifting in low-clearance areas before the mast sections begin to extend. The
maximum fork height is 131.5 in or 3340 mm.
The mast tilts forward by 6 degrees and backward by 11 degrees to facilitate
load handling and secure transport. The fork carriage width is 40 in or 1016 mm.
The standard fork dimensions are 1.6 in thick, 5.0 in wide, and 42 in long,
which is 40 mm by 127 mm by 1067 mm. Alternative fork lengths of 48 in are
available. The maximum fork spread is 40 in or 102 cm.
Load Capacity: 4,000 lb (1,814 kg)
Load Centre: 24 in (600 mm)
The lift speed with a load is 118 ft/min or 0.60 m/s,
and without a load, it increases to 126 ft/min or 0.64 m/s. Lowering speeds are
controlled at 98 ft/min or 0.50 m/s both laden and unladen. The truck can
generate a maximum drawbar pull of 4250 lb or 1928 kg when laden. Its
gradeability is 41 percent when laden and 23 percent when unladen.
The overall length of the truck, including the standard
42 in or 1067 mm forks, is 101.4 in or 2576 mm when measured to the fork face.
The overall width is 45.3 in or 1151 mm. The height to the top of the overhead
guard is 83.1 in or 2111 mm. Ground clearance, laden, is 3.7 in or 94 mm below
the mast, and 5.5 in or 140 mm at the centre of the wheelbase. The basic
right-angle stacking aisle width is 103.2 in or 2621 mm, to which load length
and clearance must be added.
The outside turning radius is 84.7 in or 2151 mm. The truck's operating weight
is 7080 lb or 3211 kg. The truck has a wheelbase of 65.0 in or 1651 mm. Its
gross weight without load is 7080 lb or 3211 kg, with axle loadings shifting
from 3130 lb or 1420 kg on the front and 3950 lb or 1792 kg on the rear when
unladen, to 9750 lb or 4423 kg on the front and 1330 lb or 603 kg on the rear
when carrying a full load.
