Rolling resistance coefficient is one of the basic resistance when moving objects. In case of objects not equipped with a motor-driven wheels and suspension system , such as: wheelchairs, mobile machinery chopper, shelving and warehouse trucks all resistances are overcome by the muscle strength of the operator. Research is carried out to limit this phenomenon, however, there is a lack of methods for measuring this parameter in the real operating conditions of devices with a wheels and suspension system without a drive unit. The article presents an innovative method of measuring the rolling resistance coefficient of objects equipped only with the wheels and suspension system accordant with the patent application P.424484 and the developed device for these tests in accordance with patent application P.424483. Additionally, the paper presents the results of preliminary tests on the measurement of pivoting coefficient of a transport truck loaded with a given mass.
Key words: rolling resistance / wheelchairs / mobile machinery chopper / method of measuring the rolling resistance / non-pneumatic wheels
