The invention provides a crane, a hydraulic control system and a winding control system. The winding control system comprises a master control valve set and a winding motor. The first oil port of the winding motor is connected with the first work oil port of the master control valve set, and the second oil port of the winding motor is connected with the second work oil port of the master control valve set. The winding control system further comprises a first oil supplement pipeline. The oil inlet of the first oil supplement pipeline is used for being connected with a system oil supplement oil way, the oil outlet of the first oil supplement pipeline is connected with the oil return port of the master control valve set, and the second oil port of the winding motor is communicated with the first oil supplement pipeline through a second oil supplement pipeline. The winding control system solves the problem that a winding control system in the prior art is low in safety.
