The invention discloses a hydraulic control method for a marine crane winch, which comprises the following steps: in a manned mode and a loading mode, switching of a manned and loading switching valve is controlled, and a switching oil way controls and limits oil way hydraulic pressure through a loading limiting valve and a manned limiting valve respectively, so that a loading limiting effect is realized; a full-hydraulic load limiting mode is adopted, and for a crane manned winch installed on an oil tanker or a liquefied natural gas ship, due to the fact that no electric control exists, expensive anti-explosion components are not needed, the control logic is simple and reliable, and the fault rate is low.
本发明公开了一种船用起重机绞车液压控制方法,在载人模式和载物模式下,通过控制载人载物切换阀的切换,切换油路分别经载物限载阀和载人限载阀控制限制油路液压,进而实现限载效果;采用全液压限载的方式,对于安装在油轮或液化天然气船上的起重机载人绞车,由于没有电气控制,不需要价格昂贵的防爆元器件,控制逻辑简单可靠,故障率低。
