摘要
本文叙述独臂架门座式起重机变幅机构的工作原理,分析常规变幅机构,即在减速箱高速轴端的两侧安装两个高速轴制动器实现臂架变幅机构的制动。这种设计存在臂架坠落的重大安全隐患,对此提出了相应的解决方案。
This paper describes the armed frame gantry crane luffing mechanism working principle, analysis of the luffing mechanism is the routine deceleration in the high-speed shaft is installed on both sides of the box two high speed shaft brake, brake arm luffing mechanism to achieve, there are significant security risks of jib falling, this design in this regard, the author put forward the corresponding solutions for reference.
