Gantry crane selection is divided into four steps

Gantry crane is also called gantry crane, which is a kind of crane we often see in port cargo yard. It has a large range of action, a high utilization rate of the site, a wide range of applications, and strong versatility. Our common gantry cranes are mainly divided into general types, hydropower stations, shipbuilding and containers. When choosing, users should make a reasonable choice according to their own use environment. The gantry crane selection is divided into four steps.
Gantry crane
 
1. Relevant regulations
 
　　 Need to comply with the relevant regulations of general gantry crane GB/T14406-1993 and GB5905-86.

　　 Under normal circumstances, the lifting capacity is less than 50t, and the span is less than 35m. There is no special requirement for use, and the single main beam type should be used. If the door leg width is large, the working speed is high, or heavy and long pieces are frequently lifted, the double-beam gantry crane should be selected.

2. Span and cantilever length

　　 The span of the gantry crane is an important factor affecting the quality of the crane itself. In the selection, the span should be minimized on the premise that the equipment use conditions and the span series standards are met.

Three, the principle of determining the wheelbase

　　 must be able to meet the stability requirements of the mast along the crane track;

　　The overall dimensions of the cargo should be able to smoothly pass through the flat steel frame of the outrigger;

　　 Pay attention to make the track B and the span S have a certain proportional relationship, generally take the track B=(1/4—1/6)S.

Four, gantry crane spacing size determination

　　During work, there should be a certain amount of space between the external dimensions of the gantry crane and the cargo and transportation vehicle passages in the yard to facilitate loading and unloading operations.

　　 When loading and unloading the general transportation vehicles in the span, keep a distance of more than 0.7m from the door legs. The spreader should have a distance of more than 0.5m from the transport vehicle when it is not working, and should have a distance of more than 0.5m when the goods pass through the door legs.
 
　　The gantry crane selection is completed in four steps. You should have a clear image of what equipment you need. The following is to choose equipment of different brands. When choosing a brand, users should fully understand the qualifications of the company and the production specifications of the equipment to ensure the quality of the equipment and make it fully functional.
