Hyster H2.50DX Specifications
The Hyster H2.50DX is a 2,500 kg (5,500 lb) capacity
internal-combustion forklift designed to deliver rugged, reliable performance in
general-purpose industrial environments. As part of the Hyster DX series, this
model emphasizes mechanical simplicity, low lifetime operating cost, and
durability.
The H2.50DX sits in the mid-capacity class used
widely in manufacturing, warehousing, fabrication, logistics, recycling
operations, and construction supply yards. It is well known for its
robust chassis, efficient powertrain, responsive hydraulic system, and
strong parts support.
The DX series was engineered during a transitional era in forklift
design—prior to the widespread adoption of complex electronic management
systems—resulting in machines with stronger mechanical serviceability
and reduced electronics.
The H2.50DX benefits from a stable masted
structure, well-balanced weight distribution, and dependable hydrostatic
steering. Operators value its predictable driving feel, smooth lifting,
and ease of servicing. Combined with reasonable fuel consumption and
long-life components, the H2.50DX remains popular in regions where
reliability and maintainability are more important than advanced
electronic features.
The H2.50DX utilizes a heavy-duty welded-steel chassis, industrial
engine, hydraulic powershift transmission, and a durable mast system
capable of mated attachment operations. Its design allows efficient
operation on paved outdoor surfaces as well as in indoor warehouse
spaces. Safety, stability, and ergonomic access to controls were key
design focus points.
The H2.50DX is usually powered by an LPG or diesel
industrial engine depending on regional configuration.
Common engine options include:
- 2.2 L to 2.5 L four-cylinder LPG engine
- 2.5 L to 2.7 L diesel engine
Basic Engine Characteristics:
- Displacement: approx. 2.2-2.7 L
- Rated power: approx. 40-55 hp (30-41 kW)
- Rated torque: approx. 100-130 lb-ft (135-176 Nm)
- Fuel: LPG or diesel
- Idle speed: approx. 650-750 rpm
- Compression ratio (diesel): approx. 17-19:1
- Compression ratio (LPG): approx. 9-10:1
Diesel versions provide higher low-speed torque and extended fuel range, while
LPG engines are better suited to indoor operations due to reduced emissions.
Lubrication System
The engine uses a full-pressure wet-sump lubrication system.
- Oil pump: gear-type
- Oil capacity: approx. 4.0-5.0 L (4.2-5.3 qt)
- Normal oil pressure: 20-30 psi (138-207 kPa) at idle; 50-70 psi (345-483 kPa)
at operating rpm
- Oil type: SAE 10W-30 or SAE 15W-40 depending on climate
Lubrication ensures stable protection for crankshaft bearings, camshaft
bearings, valvetrain, piston cooling (if equipped), and accessory drives.
Cooling System
Cooling is provided by a forced-circulation liquid cooling system.
- Pump: belt-driven centrifugal
- Coolant capacity: approx. 7-8 L (7.4-8.4 qt)
- Thermostat opening temperature: approx. 82°C (180°F)
- Cooling system pressure: approx. 13-15 psi (90-103 kPa)
A shrouded mechanical fan provides airflow across the radiator. Radiator
cleaning is essential in dusty industrial applications.
Transmission
The H2.50DX uses a rugged hydraulic powershift transmission.
- Type: single-speed powershift
- Forward travel speed (unladen): approx. 18-19 km/h (11-12 mph)
- Reverse travel speed: similar to forward
- Transmission fluid capacity: approx. 6-8 L (6.3-8.4 qt)
- Transmission fluid type: ATF Dexron II/III or similar
The torque converter ensures smooth acceleration and minimal driveline shock,
especially during frequent forward-reverse cycles typical in warehouse
operations.
Drive Axle
The front drive axle is a heavy cast-steel housing with reduction gearing.
- Axle lubrication capacity: approx. 2.0-2.5 L (2.1-2.6 qt)
- Lubricant type: SAE 80W-90 gear oil
Brakes
The braking system is durable and designed for moderate-to-heavy industrial use.
- Service brakes: hydraulic drum brakes
- Parking brake: mechanically applied hand-lever brake
Brakes are service-friendly and contain few electronic components.
The H2.50DX uses a 12-volt electrical system.
- Battery capacity: approx. 70-80 Ah
- Alternator output: approx. 50-70 A
- Starter motor rating: approx. 1.8-2.2 kW
- Diesel engines use glow plugs
- LPG engines use electronic ignition
The electrical system powers warning lights, gauges, safety interlocks, and
optional lighting.
The chassis is a welded-steel frame engineered for
heavy industrial service life.
Drive Configuration:
- Drive: front-wheel drive
- Steering: rear-wheel, hydraulic
- Axle type: oscillating rear axle for improved stability
Tires:
- Front: approx. 7.00-12 (pneumatic or cushion)

turning indoors.
Steering is fully hydrostatic with rear-wheel steering for superior agility in
tight areas.
Steering Characteristics:
- Steering type: hydraulic orbitrol
- Pump flow: approx. 6-10 L/min (1.6-2.6 gpm)
- Steering angle: approx. ±90°
- Turning radius: approx. 2.1-2.3 m (83-91 in)
The hydraulic system drives lift, tilt, and optional
attachments.
Hydraulic Characteristics:
- System pressure: approx. 2,000-2,500 psi (138-172 bar)
- Pump type: gear-type engine-driven pump
- Pump flow: approx. 25-35 L/min (6.6-9.2 gpm)
