Single girder overhead crane is a kind of top running crane as it travels on top of rails that are mounted on runway beam, thus this type of crane features maximum lifting height. The runway beam is usually supported by building columns or engineered columns to which the loads can be transmitted.
The basic components of overhead crane include bridge, hoist trolley, crane travelling mechanism and electrical device.
Bridge – The main structure of the crane that travels horizontally along runway beam. The bridge is composed of a single girder and two end beams. It also serves as main load-bearing member for that it supports the hoisting and trolley mechanism as well as the load weight.
Trolley mechanism – The most essential part of overhead lifting equipment as it undertakes the main lifting task. Trolley mechanism consists of two main parts, hoisting mechanism that is used for raising and lowering loads, and a trolley that travels in a direction parallel to bridge girder. The hoist is mounted on trolley.
Crane travelling mechanism – The part that drives the whole crane to travel back and forth. It can run either on top of runway beam or at the bottom flange of it depending on the overhead crane type.
Electrical device – The component that supplies power for crane and trolley movement. The power of crane travelling mechanism is usually supplied by conductor, and that of trolley mechanism by festoon cable.
Control system – The system that controls the operation of lifting equipment. The control options of single girder crane include pendant control, wireless remote control and cabin control.
If the typical single girder overhead crane cannot meet your needs, such as the parameters of span and lifting height is out of given range, Yufei group has the capability to provide customized design according to your special requirements.
