Hyster H55XM Specifications
The Hyster H55XM is a 2.5-tonne (5,500 lb) capacity,
gas/LPG-powered, seated rider forklift, engineered for reliable performance in
medium-duty material handling applications. As a core model in Hyster's XM
series, this forklift is designed for versatility in industries such as
warehousing, distribution, manufacturing, and logistics. Powered by a choice of
advanced engines including the GM 3.0L or Mazda 2.0G LPG units, it delivers
responsive power and efficient operation.
Its robust construction, pneumatic tires, and choice of 2-stage or 3-stage masts
ensure productive, safe, and efficient operation. Operator comfort and safety
features, including the MONOTROL pedal for direction control, hydrostatic power
steering, and adjustable features, contribute to exceptional handling confidence
and reduced operator fatigue.
The Hyster H55XM is a counterbalanced pneumatic tire forklift truck designed for
versatility and safety. It operates on gas or LPG and is controlled by a seated
operator. Its rated load capacity is 2495 kg (5500 lb) at a 610 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 1623 mm (63.9 in).
The total weight of the standard truck when unladen is 4064 kg (8960 lb). When
fully laden, the static axle loading on the front axle is 5880 kg (12962 lb) and
on the rear axle is 759 kg (1674 lb). When unladen, these figures shift to 1908
kg (4207 lb) on the front and 2761 kg (6089 lb) on the rear.
Basic Technical Data: The main component of the Hyster
H55XM is available with multiple engine options to suit various application
requirements. The primary engine option is the GM 3.0L engine, a four-cylinder
unit. It has a total displacement of 3.0 L (181 cu.in). The engine is rated to
produce 46 kW (62 hp) on gas and 44 kW (58.9 hp) on LPG at a governed no-load
speed of 2900 rpm.
An alternative engine option is the Mazda 2.0G engine, a four-cylinder unit with
a displacement of 2.0 L (121 cu.in). This engine is rated to produce 31 kW (42
hp) on both gas and LPG at a governed no-load speed of 2800 rpm.
Lubrication and Cooling: The system is designed to support continuous operation
in demanding conditions. The engine employs a forced lubrication system with
full-flow filtration to protect internal components. Liquid cooling is
maintained by a belt-driven centrifugal water pump and a radiator designed for
efficient heat dissipation. The cooling system is engineered to maintain optimal
operating temperatures during extended use. Regular inspection of the cooling
system for leaks and proper coolant level is recommended.
Transmission: The H55XM is equipped with a powershift
transmission featuring a torque converter and MONOTROL pedal for gear change.
The MONOTROL pedal allows operators to control direction and acceleration with a
single pedal, reducing operator fatigue and improving productivity. The standard
transmission features one forward gear and one reverse gear for simple,
intuitive control.
Travel Speed: The forklift achieves a maximum travel speed of 20.4 km/h (12.7
mph) when unladen and 19.6 km/h (12.2 mph) when fully laden with the standard
1-speed powershift transmission. The reverse speeds are consistent with forward
speeds, ensuring reliable maneuverability in both directions.
Axles and Brakes: The truck uses a drive axle configuration with two driven
wheels on the front (2x2). The service brake system is hydraulic with foot
control, providing reliable stopping power. The parking brake is mechanical with
hand control. The brakes are designed for durability in demanding applications.
The electrical system operates at 12 V with a battery
rated at 305 cold cranking amperes. The system is responsible for starting the
LPG engine and powering all lights and operator interface components. The system
features moisture-resistant electrical connectors for durability. The alternator
and starter are designed for reliable operation in industrial environments.
The Hyster H55XM is fitted with pneumatic tires,
designed for traction and comfort on various indoor and outdoor surfaces. It has
four wheels in total, with the front two being the driven wheels. The front tire
size is 28x9-15-12 Ply (711 mm x 229 mm x 381 mm). The rear tire size is
6.50x10-10 Ply (165 mm x 254 mm). The front tread width is 970 mm (38.2 in), and
the rear tread width is 968 mm (38.1 in). The body and frame are constructed of
fully welded heavy gauge steel for durability. The truck features integral tie
downs for secure transport.
The Hyster H55XM features hydrostatic power steering with a robust steering
system designed for precise control. The steering system requires minimal effort
from the operator, especially during low-speed maneuvering. The mast and fork
carriage can tilt forward by 6 degrees and backward by 6 degrees to facilitate
load handling and secure transport.
The hydraulic system is a core component for lift and
tilt operations. The auxiliary hydraulic relief pressure for attachments is 155
bar (2250 psi). A safety valve provides extra safety and prevents uncontrolled
lowering of the load at all times. The hydraulic system is designed for
leak-free operation with quality seals and fittings throughout.
The Hyster H55XM is equipped with lifting systems
available in 2-stage and 3-stage configurations, including limited free lift and
full free lift options. The standard 2-stage limited free-lift mast has a
maximum fork height of 3327 mm (131.0 in). With the mast fully lowered, the
height to the top of the mast is 2172 mm (85.5 in). The free lift for standard
2-stage limited free lift mast is 140 mm (5.5 in).
At maximum lift, the mast extends to a total height of 4554 mm (179.3 in)
including the load backrest extension and 3942 mm (155.2 in) without load
backrest. Optional 3-stage full free-lift masts offer lift heights up to 4415 mm
(173.8 in) with free lift of 947 mm (37.3 in) with load backrest and 1562 mm
(61.5 in) without load backrest. The standard forks have dimensions of 38 mm
(1.5 in) thick, 127 mm (5.0 in) wide. The fork carriage is designed for
durability with hook-type mounting.
Load Capacity: 5,500 lb (2,495 kg)
Load Centre: 24 in (610 mm)
The lift speed for the 2495 kg (5500 lb) rated load is
0.64 m/s (125.0 ft/min) when unladen and 0.59 m/s (116.0 ft/min) when laden for
standard 2-stage masts. Optional 3-stage full free lift masts provide lift
speeds of 0.60 m/s (119.0 ft/min) unladen and 0.56 m/s (111.0 ft/min) laden.
Lowering speed is controlled at 0.42 m/s (83.0 ft/min) for unladen and 0.50 m/s
(99.0 ft/min) for laden conditions.
The maximum drawbar pull for gas/LPG models with 1-speed powershift transmission
is 19.0 kN (4270 lbf). Drawbar pull at 1 mph is 19.7 kN (4420 lbf) for gas
models and 18.5 kN (4160 lbf) for LPG models. The maximum gradeability is 28%
without load and 31% with load for gas models. LPG models achieve 28%
gradeability without load and 29% with load.
The overall length from the front face of the backrest
to the fork face is 2619 mm (103.1 in). The overall width with single tires is
1204 mm (47.4 in). The height of the standard overhead guard is not detailed in
the provided source material. The step height from ground to running board is
not detailed. The seat height is not detailed in the provided source material.
Ground clearance at the lowest point unladen is 132 mm (5.2 in). At the centre
of the wheelbase, ground clearance unladen is 175 mm (6.9 in). For maneuvering
in aisles, the right-angle stacking aisle width with a 1219 mm (48 in) by 1219
mm (48 in) load for 90-degree stack is 2736 mm (107.7 in). The outer turning
radius is 2266 mm (89.2 in). The total weight of the standard truck is 4064 kg
(8960 lb).
