Energy-recovery generation system for handling and carrying electric vehicle

Abstract

An energy-recovery generation system for a handling and carrying electric vehicle, comprising a hoisting cylinder (), wherein an output pipeline of the hoisting cylinder () is provided with a pressure sensor unit () and a directional valve (); the directional valve () is under the control of the pressure sensor unit (); a first outlet of the directional valve () is connected to a tank () through a way of a multi-way valve () with an operating handle; the pressure oil, flowing out from a second outlet of the directional valve (), passes through a pump () having an oil suction port capable of bearing pressure or a motor, and then passes through the multi-way valve (), to finally flow back to the tank (); the pump () having an oil suction port capable of bearing pressure or the motor drives an electric motor () to output electric energy; an electric energy output end of the electric motor () is connected to an energy storage device () through a converter ().
