The invention discloses a crane energy recycling device which comprises a hydraulic pump, an overflow valve, a hydraulic oil tank, a one-way valve, an electromagnetic valve, an energy accumulator, a motor current sensor, an ascending and descending sensor and an electrical control unit. The shaft end of the hydraulic pump is connected with the high-speed end of a speed reducer of a winch. One oilopening of the hydraulic pump is connected with an oil tank, and the other oil opening of the hydraulic pump is connected with a P opening of the electromagnetic valve, an oil outlet of the one-way valve, an oil pressing opening of the overflow valve, an A opening of the electromagnetic valve and the energy accumulator. An oil suction opening of the one-way valve, an oil return opening of the overflow valve and a B opening of the electromagnetic valve are connected with the oil tank. The motor current sensor, the ascending and descending sensor and the input end of the electrical control unitare connected. The output end of the electrical control unit is connected with a coil of the electromagnetic valve. By means of the crane energy recycling device, the potential energy for heavy objectdownward putting can be sufficiently recycled and utilized; conversion links are few, and the conversion efficiency is high; and in addition, the structure is simple, a system is formed in the device, and the crane energy recycling device can be used for winches of cranes of different transmission manners such as an electrical transmission manner, a hydraulic transmission manner and a mechanicaltransmission manner.
