Gantry crane is a material handling machinery widely used in ports, docks, cargo yards, industrial and mining enterprises and other places. It has reasonable structure, reliable performance and high working efficiency, and is suitable for loading, unloading and handling of various materials in open spaces.
When choosing a gantry crane, you need to consider the following factors:
1. Lifting capacity
Lifting capacity refers to the maximum weight that the gantry crane can lift. When selecting, the required lifting capacity should be determined based on actual use requirements.
2. Span
The span refers to the distance between the legs of the gantry crane. It determines the lifting range of the gantry crane. When selecting, the required span should be determined based on the width of the working area.
3. Lifting height
Lifting height refers to the height of the gantry crane's hook from the lowest position to the highest position. When selecting, the required lifting height should be determined based on the height of the operating materials and the stacking height.
4. Work duty
Work level refers to the frequency of use and work intensity of the gantry crane. It is divided into three levels: light, medium and heavy. When selecting, the required work level should be determined based on actual usage.
5. Running speed
The operating speed refers to the operating speed of the trolley and lifting mechanism of the gantry crane. It affects the working efficiency of the gantry crane. When selecting, the required operating speed should be determined based on the job requirements.
6. Structural form
The structural forms of gantry cranes mainly include single girder and double girder. Single-girder gantry cranes have a simple structure, are light in weight, and are cheap, and are suitable for applications with small lifting capacity and small spans; double-girder gantry cranes have high structural rigidity and good stability, and are suitable for applications with large lifting capacities and small spans. Larger occasions.
7. Space requirements
When selecting a crane, you need to consider meeting the requirements of the use site, operating space and corresponding maintenance space. You should also consider the lack of limit dimensions caused by changes in the factory building during use.
