Higher Technical Content Double Girder Overhead Crane Workers To Control
Introduction:
The double-girder overhead crane has strong bearing capacity, large span, good overall stability and many varieties, but its quality is larger than that of the single-girder gantry crane with the same lifting capacity, and the cost is also higher. According to the structural form of the main beam, it can be divided into two forms: box girder and truss. Generally a box-shaped structure is used.

The difference between single girder and double girder overhead crane:
1. The two are structurally 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 double-girder bridge crane is relatively complex in structure and has a large weight, and is relatively complicated in installation and daily maintenance and repair.
2. Different production costs
Single girder overhead cranes are shorter in span and consume less construction materials, so they cost less. The double-girder bridge crane has a larger span, more consumables, and higher technical content, so the production cost is higher.
3. Differences in the way of operation
In terms of operation mode, single-girder cranes are generally operated on the ground, which 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 overhead cranes is relatively low, the rated lifting capacity is relatively small, and the work level is relatively low. The double-girder overhead crane has relatively high stability, heavier 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 weights 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.
Application:
Double-girder overhead crane is an important tool and equipment for mechanization and automation of production process in modern industrial production and lifting and transportation. Therefore, double-girder overhead cranes are widely used in indoor and outdoor industrial and mining enterprises, iron and steel chemical industry, railway transportation, port terminals and logistics turnover departments and places.
