Fuel-Efficiency in the Construction Industry

Many OEMs have created fuel efficient solutions for light duty vehicles. There has been some neglect considering the issues arising from the amount of fuel consumed in the construction industry. We wanted to highlight some of fuel efficiency initiatives taking place in the construction industry.

Volvo’s fuel efficiency tactics have shown up in the construction industry. They offer money-saving world-class excavators, articulated haulers, and wheel loaders. The CareTrack system helps manage and maximize vehicle efficiency. It is a tracking device which uses GPRS/GSM mobile network or satellite to detect the location of these machines. The system provides information such as machine utilization reports, fuel economy reports, location reports and service maintenance reports.

Also in recent news, researchers from Purdue College of Engineering have found a way to reduce the fuel consumption by improving the efficiency of the hydraulic steering systems in heavy construction equipment.
With this improvement they were able to see:

  • 14.5% fuel consumption reduction
  • 22.6% machine productivity increase
  • 43.5% fuel efficiency improvement
Heavy equipment hydraulic systems usually have a single or multiple pumps that supply flow to all valve controlled actuators that move either tools or steering mechanisms. Instead of having valves to direct the flow of hydraulic fluid to the actuators, Purdue has removed valves and provided each actuator with  a variable displacement pump. After successfully demonstrating this technology for the actuators that move the tools, Purdue has now implemented this technology for the steering system of the vehicle.
The new steering system is designed so that the actuator motion is controlled by adjusting the pump displacement. Not only does the new technology help eliminate excess wasted energy, it also offers stability control via active steering, variable-rate and variable-effort steering, increased machine productivity, improved line holding capability, and the potential for remote as well as full autonomous operation.
