Toyota 8FD50U Specifications
The Toyota 8FD50U represents a significant advancement
in the large-capacity pneumatic forklift class, offering a robust combination of
power, durability, and advanced safety features. Powered by the sophisticated
Toyota 1KD diesel engine with 74 hp, this model delivers reliable torque for
lifting and maneuvering loads up to 11000 lb (5000 kg) while meeting Tier 4
Final emission standards.
Its design prioritizes operator comfort with a spacious cabin, tilt steering
column, and vibration-isolating power steering, reducing fatigue during extended
shifts. The 8FD50U is distinguished by its comprehensive safety package,
including SAS, which actively monitors and stabilizes the truck during operation
to help prevent tip-overs.
With rugged construction features such as tilt cylinder protection boots, a
stamped steel engine hood, fully sealed air intake, and moisture-resistant
electrical connections, this forklift is engineered to withstand the toughest
outdoor conditions. The 8FD50U offers travel speeds up to 14.4 mph unladen and a
tight turning radius of 110.5 in (2810 mm), providing excellent maneuverability
for its class.
The Toyota 8FD50U is a rider-seated forklift powered by a diesel engine meeting
Tier 4 Final emission standards. It has a load capacity of 11000 lb at a 24 in
load centre, equivalent to 5000 kg at a 600 mm load centre. The distance from
the drive axle centre to the fork face is 21.9 in or 555 mm. The truck has a
wheelbase of 78.7 in or 2000 mm. Its unladen operating weight is 15920 lb or
7220 kg.
The Toyota 8FD50U is powered by the Toyota 1KD engine,
a sophisticated four-cylinder diesel power unit known for its reliability, fuel
efficiency, and compliance with stringent emission regulations.
Basic Technical Data: The engine is a four-cylinder diesel with a displacement
of 182 cu in or 2982 cc. It features a Double Overhead Cam (DOHC) design and
includes a Diesel Oxidation Catalyst for Tier 4 Final compliance. It produces a
rated power of 74 hp at 2200 rpm, equivalent to 55 kW at 2200 rpm. The engine
delivers rated torque of 220 lb-ft at 1500 rpm, equivalent to 300 Nm at 1500
rpm. The cylinder bore and stroke are designed for optimal low-speed torque
essential for material handling applications. The diesel fuel tank capacity is
32 US gal or 120 l.
Lubrication: The engine employs a forced lubrication system. 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 diesel 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,
which uses a long-life coolant (LLC). 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 8FD50U 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.
Travel Speed: This forklift achieves a laden travel speed of 13.1 mph or 21.0
km/h in both forward and reverse. When unladen, the travel speed increases to
14.4 mph or 23.0 km/h.
Axles: The front axle is a drive axle, designed to bear the majority of the load
during lifting operations. The rear axle is a steer axle, which pivots to
maintain ground contact on uneven surfaces. Both are robustly constructed to
handle the stresses of daily use. The wheel configuration features 2 driven
wheels at the front and 2 steer wheels at the rear.
Brakes: Service braking is handled by a hydraulic braking system, providing
reliable and progressive deceleration essential for safety when handling loads.
The parking brake is hand-operated.
The electrical system operates at a standard 12 volts
with a battery capacity of 70 Ah (5-hour rating). The system powers the starter
motor, lights, and electronic control units. It includes moisture-resistant
electrical connections for reliable operation in outdoor environments.
The System of Active Stability (SAS) and other
electronic controllers rely on a network of sensors and actuators to
function correctly. The system also includes an LCD multi-function
display and Controller Area Network (CAN-BUS) communications for
enhanced diagnostics and monitoring.
The chassis is a heavy-duty, welded steel structure
that supports all major components: the engine, drivetrain, counterweight, and
mast. The design includes durable features such as tilt cylinder protection
boots, a stamped steel engine hood, fully sealed air intake, and plate-iron
front fenders.
The truck is fitted with pneumatic tires, which provide stable performance and
shock absorption on uneven surfaces common in outdoor applications. The front
tires are size 300-15-20PR, and the rear tires are size 7.00-12-12PR or
7.00-12-14PR depending on configuration. The wheel configuration is 2 driven
wheels at the front and 2 steer wheels at the rear. The front tread width is
45.3 in or 1150 mm, and the rear tread width is 43.3 in or 1100 mm.
The 8FD50U features full hydraulic power steering with load-sensing and
vibration-isolating technology, 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 truck also includes a tilt steering column, allowing operators to adjust the
steering wheel to their preferred position for added comfort and personalized
ergonomics.
The hydraulic system powers the lifting, tilting, and
auxiliary functions such as sideshift. The system is designed for precise load
control and efficient operation. It includes a hydraulic pump, control valve,
lift cylinders, and tilt cylinders.
The operating pressure for attachments is rated
at 2630 psi or 185 kg/cm2. The rated pump flow is 33.8 gpm or 128 lpm.
The system features automatic fork leveling, which levels the fork
parallel to the ground from the back tilt position with the touch of a
button.
The forklift can be equipped with various mast types,
including simplex and duplex configurations, featuring a structurally rugged
mast channel design. The standard mast configuration with V mast has a lowered
height of 96.5 in or 2450 mm. It provides a free lift of 4.7 in or 120 mm,
enabling lifting in low-clearance areas before the mast sections begin to
extend.
The maximum fork height is 120 in or 3050 mm. The mast tilts forward by 6
degrees and backward by 12 degrees to facilitate load handling and secure
transport. The standard fork dimensions are 2.4 in thick, 6.0 in wide, and 48 in
long, which is 60 mm by 150 mm by 1220 mm. The maximum fork spread is 45.7 in or
1160 mm.
Load Capacity: 11,000 lb (5,000 kg)
Load Centre: 24 in (600 mm)
The lift speed with a load is 94 ft/min or 0.48 m/s,
and without a load, it increases to 106 ft/min or 0.54 m/s according to some
sources. Lowering speeds are 106 ft/min or 0.54 m/s with a load and 0.49 m/s
without a load. The truck can generate a maximum drawbar pull of 8100 lb or 3700
kg when laden. Its gradeability is 31 percent.
The overall length of the truck, including the standard
48 in or 1220 mm forks, is 124.8 in or 3170 mm when measured to the fork face.
The length to the face of the forks is 10.5 ft or 3.2 m. The overall width is
57.1 in or 1450 mm. The height to the top of the overhead guard is 90.6 in or
2300 mm.
Ground clearance, laden, is 4.7 in or 120 mm below the mast, and 9.1 in or 230
mm at the centre of the wheelbase. The basic right-angle stacking aisle width is
132.5 in or 3370 mm, to which load length and clearance must be added. The
outside turning radius is 110.5 in or 2810 mm. The truck's operating weight is
15920 lb or 7220 kg.
