摘要
实际工程中出现的钢吊车梁振动和摇晃现象,通常会影响吊车的正常工作甚至安全,通过现场观察和理论分析,找出产生这种现象的原因,提出解决问题的具体方法供同行参考。
The vibration and sway of crane beam affect its daily use, even safety of light steel mill building. After field observations and theoretical analysis, the reasons are found out and some solutions are proposed which may be a reference for similar projects.
