Beschreibung
Zusammenfassung:	The invention discloses a gantry lifting and potential energy recovery hydraulic circuit. The hydraulic circuit comprises a working interface, a positive and negative rotation oil pump, a main motor,an auxiliary oil pump, an auxiliary motor and a hydraulic control proportional valve, wherein the working interface is used for being communicated with the working cavity of a working oil cylinder; the main motor is in mechanical transmission connection with the positive and negative rotation oil pump so as to drive the positive and negative rotation oil pump to work in an electric mode to supplyoil, and to return oil in a power generation mode to be capable of driving the positive and negative rotation oil pump to rotate to generate power; the auxiliary motor is used for driving the auxiliary oil pump to work to supply oil; one side of the hydraulic control proportional valve is communicated with the working interface; and the other side of the hydraulic control proportional valve is communicated with the positiv
