HITACHI CONSTRUCTION MACHINERY

Boarding a clean engine complying with the rigorous emission regulations.

Boarding Clean Engine
A clean engine complying with the emission regulations Stage III in EU and Tier 3 in US (EPA) is boarded to reduce emissions containing nitrogen oxide (NOx) and particulate matter (PM).

Low Noise Engine
Engine noise is reduced by approximately 2 dB with the robust engine. It goes without saying that the engine meets the EU noise regulations.

Variable-Speed Fan
The engine cooling fan is a large 1 120 mm diameter variable-speed electro-hydraulic fan. This fan automatically starts when temperature comes into the high temperature range, ensuring low noise operation.

Proven Muffler
A proven large muffler is provided to reduce sound and exhaust emissions greatly.

Using Aluminum Radiator, Oil Cooler and Air-Conditioner Condenser
The aluminum radiator, oil cooler and air-conditioner condenser are utilized for the sake of recycling and for increased durability.

Marking of Recyclable Parts
All resin parts are marked for the sake of recycling. This helps ease the separation
of recyclable wastes.

Reducing the Burden to the Environment
Lead-free design is achieved through the use of lead-free wire harness covering, radiator, oil cooler and others. No asbestos is used. The use of aluminum radiator, oil cooler and intercooler increases the durability of the machine.

Biodegradable Hydraulic Oil (Optional)
Degradable hydraulic oil is ecological, which is decomposed into water and carbon dioxide in water and ground.
