The invention discloses a hydraulic system, a control method and hoisting equipment. The technical problems that in the prior art, hoisting equipment is not easy to control in use and low in stability, and potential safety hazards exist are solved. The hydraulic system is applied to the hoisting equipment comprising a first winch and a second winch. The hydraulic system comprises a hydraulic pump, a first hydraulic motor, a second hydraulic motor, a parking module, a first one-way valve, a first overflow valve, a second one-way valve and a second overflow valve, wherein the first one-way valve and the first overflow valve are connected in parallel, and the second one-way valve and the second overflow valve are connected in parallel. The first hydraulic motor and the second hydraulic motor are used for driving a first winch and a second winch respectively. The cable can be always kept in a tensioned state during cable unwinding and cable winding, the second winch can rotate earlier than the first winch during cable winding, and the second winch stops later than the first winch when cable winding is stopped; meanwhile, the first winch releases the rope earlier than the second winch during rope releasing, and the second winch stops earlier than the first winch when rope releasing is stopped.
本发明公开了一种液压系统、控制方法以及卷扬设备,解决现有技术中的卷扬设备的使用存在不易控制、平稳度较低、存在安全隐患的技术问题。该液压系统应用于包括第一绞车和第二绞车的卷扬设备。所述液压系统包括液压泵、第一液压马达、第二液压马达、驻车模块、并联的第一单向阀和第一溢流阀以及并联的第二单向阀和第二溢流阀,所述第一液压马达和所述第二液压马达分别用于驱动第一绞车和第二绞车;能实现出绳和收绳时缆绳均能始终保持张紧的状态,可以实现收绳时第二绞车比第一绞车先转动、收绳停止时,第二绞车比第一绞车后停止;同时放绳时第一绞车比第二绞车先放绳、放绳停止时第二绞车比第一绞车先停止的技术效果。
