Green Machines – New Trend in the Construction Industry

Construction Jobs — Tue, 29 Jun 2010 13:11:11 +0000

An average construction machine needs 15 to 20 gallons of diesel per hour. Taking into consideration unpredictable fuel prices that may go sky high unexpectedly, it is no surprise that the construction machinery welcomes all ways to become independent of it. Of course, there are also the environmental issues at stake, especially reduction of carbon dioxide emissions, but the economic factor is the most crucial. That is why many manufacturers producing construction machinery work on new fuel-efficient solutions that could be advantageous for their vehicles.

The first green machine that appeared on the market is a hydraulic excavator – Komatsu PC200-8 Hybrid. It uses an ultracapacitor bank to store energy generated during the swing movement of the upper structure. The ultracapacitor bank converts it to electricity that is later used to power a motor which assists the engine. As a result, the machine is the most fuel efficient when the upper structure is in use. Depending on the task it performs, it can save 25 to 40% fuel compared to the non-hybrid model.

Another company that followed the green trend is Caterpillar. The company introduced the world’s first hybrid truck-type tractor known as Cat D7E. What is interesting, the dozer is even more powerful than the non-hybrid model, but uses 10 to 30% of fuel less. It is possible due to a combination of a diesel engine and an electric motor.

Kobelco Construction Machinery launched its 8-ton class SK80 hybrid hydraulic excavator this year. For the time being it is available only in Japan. It uses 40% less fuel compared with a conventional machine of that size. Energy savings are made by recovering energy from swing deceleration and recycling excess energy from engine idling.

Apart from fuel-efficiency, all the above mentioned vehicles share also another advantage – they are extremely quiet in operation, therefore perfect for use in urban areas.

Some other companies are also working on hybrid technologies to introduce them to their machines, but the process is not easy… Caterpillar needed 10 years to launch their vehicle onto the market.
