Bridge cranes can be divided into single girder and double girder bridge cranes.
What's the difference between the Single and Double girder bridge overhead cranes?
Generally, the single girder bridge crane is relatively simple structure, light weight and relatively simple in installation, routine maintenance and assembly and disassembly. But the structure of the double girder bridge crane is relatively complex, its own large weighte, and it is relatively complex in installation and routine maintenance and repair.
2. The cost of production
The single girder overhead traveling crane is shorter in span and consumes less construction materials, so the cost is lower. The double girder bridge crane has larger span, more consumables and higher technical content, so the production cost is higher.
3. Different modes of operation
The single beam crane is generally operated on the ground, and can be operated in two ways by the handle and the remote control, while the double beam bridge crane requires the workers to control the operation.
4. Mechanical properties
The stability of single girder bridge cranes is relatively low, the rated lifting load is relatively small, and the level of work is relatively low. The double girder bridge crane is relatively stable, the rated load is heavier, and the work level is relatively high.
5. different environment
Generally speaking, single girder bridge cranes are suitable for workplaces with short span, relatively light weight and small space for construction sites. The double girder bridge crane is suitable for long span, relatively heavy lifting and wide space for construction sites.
