Hyster H50UT Specifications
The Hyster H50UT is a 5,000-lb (2,268-kg) capacity
internal-combustion, pneumatic-tire forklift designed for general industrial,
manufacturing, and warehousing operations that require reliable performance with
low operating costs. As part of the Hyster UT Series, the H50UT represents a
simplified design philosophy focused on durability, ease of use, and service
accessibility.
Unlike advanced Fortis or XT models, the UT
line avoids complex electronics and unnecessary automation, instead
offering a strong steel construction, proven hydraulic systems,
dependable engines, and components engineered for longevity.
The H50UT is widely appreciated by small and mid-size operations due to
its affordability, rugged construction, predictable operating
characteristics, and straightforward maintenance procedures. Its
ergonomic operator compartment, stable mast, wide-view design, and
durable tires make it suitable for a variety of environments - from
indoor concrete floors to semi-rough outdoor yards.
The H50UT is ideal for companies needing
dependable lifting without the cost or complexity of premium forklift
lines. Paired with access to global Hyster parts support, the H50UT is a
practical solution for multi-shift operations.
The H50UT generally comes equipped with a modern,
industrial 2.2- to 2.5-liter four-cylinder internal-combustion engine offered in
diesel, gasoline, or LPG configurations depending on market requirements. These
industrial engines are chosen for their low fuel consumption, steady torque
output, and long life.
Engine Specifications:
- Displacement: approximately 2.2-2.5 L
- Rated power output: approximately 45-55 hp (33-41 kW)
- Peak torque: approximately 95-115 lb-ft (129-156 Nm)
- Fuel types: diesel or LPG/gasoline
- Idle speed: approximately 650-750 rpm
- Maximum speed: approximately 2,500-2,700 rpm
The engines are designed for industrial duty cycles with reinforced crankcases,
heavy connecting rods, and simplified fuel systems to minimize service downtime.
Lubrication System
The lubrication system is a full-flow, pressurized wet-sump system.
- Oil pump: gear-type
- Oil capacity: approximately 4.0-5.0 L (4.2-5.3 qt)
- Normal oil pressure: 20-30 psi (138-207 kPa) at idle
- High-speed oil pressure: up to 60-70 psi (414-483 kPa)
- Recommended oil weight: SAE 10W-30 or 15W-40 depending on environment
Spin-on filters make servicing clean and fast. High-duty applications require
more frequent oil changes.
Cooling System
The cooling system uses a cross-flow radiator, belt-driven centrifugal pump, and
shrouded fan for efficient airflow.
- Coolant capacity: approximately 7-8 L (7.4-8.4 qt)
- Thermostat: opens at approximately 82°C (180°F)
- System pressure: 12-15 psi (83-103 kPa)
The cooling package is suitable for high-cycle loading and warm climates with
extended run times.
Transmission
The H50UT features a robust hydraulic powershift transmission engineered for
smooth directional changes and minimal shock loads to the driveline.
- Type: single-speed hydraulic powershift
- Forward speed (unladen): approximately 10-12 mph (16-19 km/h)
- Reverse speed: approximately 10-11 mph (16-18 km/h)
- Transmission fluid capacity: approximately 6-8 L (6.3-8.4 qt)
- Recommended fluid: ATF Dexron III or high-quality equivalent
Directional shifting is performed through a mechanical lever controlling
hydraulic clutch packs.
Drive Axle
The front drive axle is a rugged cast-steel assembly designed to support both
lift loads and traction forces.
- Lubrication capacity: approximately 2-2.5 L (2.1-2.6 qt)
- Lubricant: SAE 80W-90 gear oil
Planetary hubs may be included depending on variant to improve torque transfer.
Braking System
Brakes are durable and industrial in design.
- Service brakes: hydraulic drum brakes (front axle)
- Parking brake: mechanical hand-lever drum brake
The drum braking system has proven dependable for industrial environments and
requires periodic adjustment.
The H50UT’s electrical system is simple and robust.
- Voltage: 12 V
- Battery capacity: approximately 70-80 Ah
- Alternator output: approximately 50-70 A
- Starter motor rating: approximately 1.8-2.2 kW
- Engine control: electronic ignition for LPG models
Electronics are minimized to improve reliability, especially in dusty or
high-vibration environments.
The H50UT utilizes a welded-steel chassis engineered to
withstand repeated load cycles and frequent directional changes.
Drive Configuration:
- Drive wheels: front
- Steering wheels: rear
- Drive mode: 2WD
The H50UT is available with pneumatic or solid pneumatic tires.
Tire sizes:
- Front tires: approximately 7.00-12
- Rear tires: approximately 6.00-9
Pneumatic tires provide cushioning and traction on semi-rough yards, while solid
pneumatics withstand debris and puncture hazards.
Rear-wheel steering provides agility in tight spaces.
Steering:
- Steering type: fully hydrostatic orbitrol
- Pump flow: approximately 6-10 L/min (1.6-2.6 gpm)
- Steering axle: oscillating center-pivot type
- Minimum turning radius: approximately 2.0-2.2 m (79-87 in)
Hydrostatic steering ensures light steering effort regardless of load.
Hydraulics are engineered for durability and steady
response.
- Maximum hydraulic pressure: approximately 2,000-2,500 psi (138-172 bar)
- Pump type: engine-driven gear pump
- Pump output: approximately 20-30 L/min (5.3-7.9 gpm)
- Hydraulic reservoir: approximately 25-30 L (26-32 qt)
