25t门座起重机起升机构改造

Transformation of the Hoisting Mechanism on the 25t Gantry Crane

针对部分门座起重机在设计制造时可能因考虑经济性而将起升卷筒直径做得偏小,造成在使用中出现钢丝绳过快磨损而频繁更换钢丝绳,以及钢丝绳断股的安全隐患的情况,通过改变卷筒直径和调整减速箱的速比,以较经济的费用和改造工作量解决了这些问题。

Considering the economical efficiency in designing and manufacting,part of the gantry cranes＇ hoisting drums are made smaller. That causes a faster wear and more frequent replacement of the wirerope and the potential risk of rope strand breaking. This paper solves these problem with an economical cost and transformation workload by changing the diameter of drums and the speed ratio of reducer casings.
