Electric Single-girder Bridge Crane

 

A single girder overhead crane is a lifting machinery consisting of a single main girder, known for its simple and efficient design. This type of crane typically includes a beam spanning the workshop, with a running mechanism underneath for lateral movement of heavy loads. Equipped with wheels at its ends, the crane can move along tracks, facilitating material transport throughout the entire working area. The simplified structure of a single girder bridge crane is cost-effective in both manufacturing and maintenance.

European-style Electric Single-girder Crane

 

Advantages and Applications of Single Girder Overhead Cranes

 

 

Cost-effective

Single girder overhead cranes are less expensive than double girder overhead cranes.

 

Easy to install

Single girder overhead cranes are easy to install and require less space than other types of cranes.

 

Versatile

Single girder overhead cranes can be used in a variety of industries and applications.

 

 

Limitations and Scope of Single Girder Overhead Cranes

 

 

Despite various advantages, single girder bridge cranes have limitations. Due to their structural design, they are generally unsuitable for handling extremely heavy loads or complex lifting tasks. Their operating speed and lifting height may be lower compared to more complex double girder systems. Additionally, when high stability and load-carrying capacity are crucial in the working environment, single girder EOT cranes may fall short of meeting these requirements.

 

Components of a Single Girder Overhead Crane

Single girder overhead cranes consist of several components that work together to lift and move heavy loads. These components include:

 

Bridge: The bridge is the main component of the crane and consists of a single girder that spans the width of the workspace. The girder is supported by two end trucks that move along rails mounted on the building structure.


Hoist: The hoist is the component that lifts and lowers the load. It consists of a motor, gearbox, brake, drum, wire rope, hook, and block. The hoist is mounted on the bridge girder and moves along it.

Controls

The controls are used to operate the crane and include a pendant or radio remote control.

Electrification

The electrification system provides power to the crane and includes a power cable or festoon system.

End trucks

The end trucks support the bridge girder and move along rails mounted on the building structure.
