摘要
船用起重机液压越障装置,使得起重机吊臂在一定高度内限幅回转,超过一定高度又能继续回转越过障碍物,该装置能有效防止吊臂碰撞事故的发生,降低起重机操作人员的劳动强度,提高起重机作业安全性,同时具有结构简单、成本低、工作可靠等特点。
The hydraulic obstacle-navigation device of boom crane for ships can not only allow limit rotary motion of the crane boom in certain height,but also continue to turn around and pass over obstacles in case of beyond certain height.This device can effectively keep booms from any collision accidents,reduce labor strength of crane operators,and improve the crane operating safety,provided with advantages such as simple structure,low cost,and reliable operation,etc.
