The invention provides a winch lifting hydraulic system and a crane, and relates to the technical field of cranes. The winch lifting hydraulic system comprises an automatic control oil way, a manual control oil way, a switching control valve and a control module; the control module controls the automatic control oil way and the switching control valve to act, and the switching control valve achieves oil way switching of the automatic control oil way and the manual control oil way under the control of the control module; when an automatic control oil way is switched, a crane winch enters an automatic control mode; and when the manual control oil way is switched, the crane winch enters a manual control mode, so that the manual control mode and the automatic control mode of the winch can be switched, the operation is more convenient, and the problem that an operator is easy to feel tired when pulling an operating handle for a long time is solved. The crane uses the winch lifting hydraulicsystem, the manual control mode and the automatic control mode of the winch can be switched, operation is more convenient, and fatigue cannot be generated.

    本发明提供了一种卷扬提升液压系统及起重机,涉及起重机技术领域。卷扬提升液压系统包括自动控制油路、手动控制油路、切换控制阀及控制模块;控制模块控制自动控制油路和切换控制阀动作,切换控制阀在控制模块的控制下实现自动控制油路和手动控制油路的油路切换;当切换到自动控制油路时,起重机卷扬进入自动控制模式;当切换到手动控制油路,起重机卷扬进入手动控制模式,由此本发明实现了卷扬的手动控制模式和自动控制模式可切换,操作更方便,解决了操作手长时间保持扳动操纵手柄易产生疲劳的问题。起重机使用了上述的卷扬提升液压系统,实现卷扬的手动控制模式和自动控制模式可切换,操作更方便,不会产生疲劳。
