Abstract
The purpose of this study is to improve the potential energy recovery to electric energy in an electrohydraulic forklift system. The initial result achieved for the energy saving ratio after structural optimization is 40%. Component optimization is applied to the tested drive; this consists of an electric servomotor with direct torque control which is directly running a reversible hydraulic pump. According to the study, the energy efficiency and the energy recovery from the electrohydraulic forklift system can be increased by 11%. New ideas and directions for further research were obtained during the study.
