吊钩闭锁装置的改进设计

Improved design of lift hook locking device

提出了起重机吊钩的闭锁装置多年来一直被模式化的问题。从改变结构、工作原理入手,设计了不同形式的闭锁装置。既达到了标准要求的安全目的,又减轻了操作的繁琐程度,提高了工作效率。

The problem that the lift hook locking device,although as a small part in the crane,is modelized for several years is proposed in this paper. Different types of locking device are designed starting from changing structure and working principles. Not only the safety objective required by the standard has been achieved,but also the complicated operation has been simplified,thus the working efficiency is improved.
