Efficiency Test Method for Wheel Loaders


Development of a test method for assessing the energy efficiency of wheel loaders

Increasing scarcity of fossil raw materials and the resulting increase in fuel costs and more stringent emission laws require an increase in the overall efficiency of mobile work machines. Assessing new drive technologies in terms of their efficiency potential requires a consistent and repeatable efficiency test method. Such a test method has not previously been available for wheel loaders, which are included amongst the most widespread construction machinery.

Research objectives

The objective of this research project was the development of a test method that enables a realistic assessment of the energy efficiency of wheel loaders under exclusion of external influences due to operation, weather, and subsoil condition yet considering representative working tasks.

  • Definition of representative test cycles for wheel loaders
  • Implementation of practical field measurements
  • Development of an approach for reproducing the test cycles on the 1 MW clamping test bed
  • Development of devices for loading the working and steering hydraulics
  • Implementation of efficiency tests on the test bed and validation of the test method
