Electric single-girder cranes and electric double-girder cranes are both very commonly used crane equipment, but they have many differences.
The electric single-girder crane has only one beam, and the electric hoist is hung upside down on the track directly below the beam, while the electric double-girder crane has two parallel beams, the electric hoist is installed on the trolley, and the trolley is placed on the track directly above superior. The double-girder crane is mainly composed of three parts: machine, electrical and metal structure. The appearance of the bridge crane is like a single-span flat bridge with translational motion on two displacement rails supported at both ends.
Double-girder cranes are mostly used in indoor and outdoor industrial and mining enterprises, railway transportation, iron and steel chemical industry, port terminals and logistics turnover and other departments and occasions. The electric single-girder crane is composed of a metal structure, an electric hoist, a cart operating mechanism, and an electrical device.
If the height of the workshop is not enough, you can choose ordinary single-girder cranes. Single-girder cranes are essential and important equipment in the manufacturing process of all workshop buildings. The application of single-girder cranes can greatly reduce the labor intensity of workers, thereby effectively improving the construction of buildings. Construction efficiency! However, many workshops did not consider the use of crane equipment in the later period when they were built at that time, so when the crane was required to be used later, the crane could not be installed normally because the height of the workshop was not enough, or the lifting height of the crane after installation Can not meet the needs of lifting! So what should we do in this situation?
1. When the height of the workshop is not enough, you can choose an ordinary single-girder crane. This is because single-girder cranes are lighter in weight than double-girder cranes, occupy less floor space, and have relatively lower environmental requirements. The electric hoist of the single-girder crane is usually suspended under the main beam, and its height is 1.5 meters.
2. If the height of the workshop still cannot meet the height requirements, a low-clearance crane can be selected. Single-girder cranes can increase the lifting height, which requires a lower workshop height and is easier to meet. Excellent single-girder cranes have the advantage of low clearance and can maximize the use of small spaces. It has a simple and compact structure, light weight, low operating cost and low energy consumption, which is beneficial to the low-cost production of the manufacturer.
Compared with the traditional single-girder crane, the single-girder crane has a novel structure and low wheel pressure. For low-altitude workshops, the single-girder crane has a small distance from the hook to the wall, low clearance height, and higher lifting height to meet the needs of low-altitude workshops.
