柔性拉索单臂架起重机臂架防后倾分析

Analyses on Back-inclination Prevention of Wire hauling Single Jib Type Cranes

在我国中、小内河港口 ,柔性拉索单臂架起重机极易发生臂架后倾事故。采取控制臂架不平衡力矩的方向、限制臂架倾角和起升高度、设置紧接断电开关等措施能有效地防止臂架后倾事故的发生。

Accidents resulting from the backclination of wirehauling single jib type cranes often happens in the medium and smallsized ports in our country,which can be effectively prevented,by means of controlling unbalanced moment of force of lifting arms,limiting the arm angle and lifting height and applying emergent offpower switch,etc.
