A hoisting system for engineering machinery comprises a closed hydraulic system, wherein the closed hydraulic system comprises a pump and a motor which are connected through a closed hydraulic loop; the winch is driven by the motor to lift or lower a load; the main winch handle is configured to be capable of being controlled to input a winch action instruction; the brake mechanism is configured to be capable of locking and releasing the winch; the control unit is configured to execute the load holding function in two control stages in the process that the winch is switched from the dynamic state to the static state, the first control stage is from the moment when the load holding function is triggered to the moment when the load reaches the static state, and the second control stage is from the moment when the load reaches the static state to the moment when the brake mechanism is closed.
一种工程机械卷扬系统包括:闭式液压系统,其中包含通过闭式液压回路连接的泵和马达;卷扬,其由所述马达驱动而提升或下放负载;主卷扬手柄,其配置成能够被操控输入卷扬动作指令;刹车机构,其配置成能够锁止和释放所述卷扬;控制单元,其配置成在所述卷扬由动到静切换过程中,以两个控制阶段执行负载保持功能,其中第一控制阶段为负载保持功能触发开始到负载达到静态,第二控制阶段为从负载达到静态开始到刹车机构关闭动作完成。
