过轨起重机是一种以电动葫芦为起升机构的具有多台起重机(或多条轨道)共用一个或多个起重小车的特殊起重机。过轨装置是过轨起重机的核心,它决定了过轨起重机能否好用。本文介绍一种新型电机驱动式过轨装置。
The overhead crane is a special crane with multiple cranes (or multiple rails) sharing one or more hoisting trolleys with electric hoists as the lifting mechanism. Off-track device is the core of the rail crane, which determines whether the overhead crane can be easy to use. This article describes a new motor-driven over-rail device.
