What is the difference between a single girder overhead crane and double girder overhead crane?

1. The structure of the two is different

Generally, single girder bridge cranes are relatively simple in structure, light in weight, and relatively simple in installation, daily maintenance, and assembly and disassembly. However, the structure of the double girder bridge crane is relatively complex, its own weight is large, and the installation, daily maintenance and repair are relatively complicated.

2. Different production costs

Single girder overhead cranes are shorter in span and consume less construction material, so the cost is lower. The double girder bridge crane has a larger span, more consumables, and higher technical content, so the production cost is higher.

3. The difference in operation mode

In terms of operation mode, single girder cranes are generally operated on the ground, and can be operated by handle and remote control, while double girder bridge cranes require workers to control them during operation.

4. Mechanical properties

In terms of mechanical performance, the stability of single girder bridge cranes is relatively low, the rated lifting capacity is relatively small, and the level of work is relatively low. The double girder bridge crane has relatively high stability, heavy rated lifting capacity, and relatively high working level.

5. The working environment of the two is different

Generally, single girder bridge cranes are suitable for workplaces with short spans, relatively light lifting capacity, and relatively small construction site space. The double girder bridge crane is suitable for sites with long spans, relatively heavy lifting capacity, and wide construction site space.
