Abstract

With the development of electric drive and energy storage technology, internal combustion forklifts are gradually replaced by electric forklifts. Electric forklift is developing towards heavy duty. The valve control mode of the forklift fork system causes a large amount of recoverable potential energy to heat up and lose in the way of throttling loss, resulting in energy waste and system temperature rise. For heavy-duty forklift, its load is larger, more energy can be recovered, and the heating phenomenon is more prominent. In order to solve the problems, a energy recovery system with hydraulic motor-motor is proposed, and the theoretical and simulation analysis on the valve control and hydraulic motor control of the hydraulic cylinder descending process is carried out. The simulation results show that the energy recovery scheme is feasible.
