HITACHI CONSTRUCTION MACHINERY

Hydraulically Operated Cooling Fan with Heat-Sensing System
Fan speed can be adjusted depending on fluid temperature to effectively cool down coolant, hydraulic oil, transmission oil and torque converter oil. The result is extended component service life and reduction in fuel consumption. The fan is also separate from the engine for easy servicing.

Capacious Hydraulic Oil Cooler
The ample cooling capacity of the hydraulic oil cooler helps reduce oil temperature fluctuation, and extend service life of components.

Transmission
The transmission can effectively reduce the transmitting load. This helps reduce sound and extend service life, enhancing reliability.

Robust Differential Gears
Differential gears are thickened to increase rigidity.

Robust Drive System
The new OHC 4-valve per cylinders engine is teamed up with strengthened cylinder head, block, crank and journal pins, and a lattice frame.

Durable Axles
Front and rear axles are improved for durability. The axle housing is thickened for tough operation at quarries.

Improved Braking Ability
The brake is a wet-type multi-plate brake, and housed in the axle.

Variable Displacement Pumps
New variable displacement pumps are exclusively developed and designed for Hitachi wheel loaders for tough earthmoving.

Protected Fuel Tank
The large counterweight is arranged to protect the fuel tank from collisions with obstacles during operation.

Aluminum Radiator and Oil Cooler
The radiator and oil cooler are made of aluminum instead of conventional steel or copper for corrosion protection.

LED Indicators and Instruments
On the indicators, monitors and alarms, many LEDs are utilized for longer service life resulting in less failure, enhancing the reliability.

O-Ring Seal (ORS) Joints and Water Resistant Electric Connectors
Numerous elaborate components are utilized for higher durability and reliability. The proven ORS joints and high-pressure hydraulic lines are utilized in the hydraulic system and waterresistant wiring connectors in the electrical system.
