Document Type and Number:

WIPO Patent Application WO/2018/119972

Kind Code:

A1

Abstract:

A crane hydraulic control system and a crane. The crane hydraulic control system comprises a prime mover (1), an execution control mechanism, a hydraulic energy conversion device (3), a running energy recycling device, and an operation energy recycling device. By means of cooperation among the operation energy recycling device, the running energy recycling device and the hydraulic energy conversion device (3), kinetic energy generated in a running brake process of the crane and potential energy generated in a heavy object drop process are respectively converted into hydraulic energy, and the hydraulic energy is recycled, stored and reused. By means of the structure, energy generated when the crane gets on a lorry and energy generated when the crane gets off from the lorry can be recycled, and energy waste is effectively reduced.
