双梁六吊点悬挂起重机过轨装置

Rail-transferring device for double-girder six-lifting-point suspension crane

介绍一种实用新型结构形式的起重机过轨锁定装置,综合了以往过轨装置的优缺点并加以改进,不仅有利于克服传统过轨装置加工精度要求高、实际使用效果不佳等缺点,而且在一定程度上提高了整个机构的可靠性、运行的安全性以及定位的准确性。

The paper introduces a utility model of crane rail-transferring locking device, which integrates advantages and disadvantages of previous rail-transferring devices, with further improvement. The new device can not only overcome disadvantages of traditional rail-transferring devices such as high processing precision requirement, and unsound actual op- eration performance, etc. , but also improve reliability of the whole mechanism, operational safety and correct positioning.
