Introduction to the advantages and uses of gantry cranes

There are many types of gantry cranes, which can be divided into the following categories according to their uses. Each type of gantry crane has a detailed introduction to its purpose.

1. Ordinary gantry crane

Among them, box and truss cranes are particularly widely used. It can transport various types of packaged and bulk materials, with a lifting capacity of less than 100 tons and a span of 4-39 meters. Ordinary gantry cranes use a grab bucket method to operate at a higher level. General gantry cranes mainly refer to hook, grab bucket, electromagnetic, hoist gantry cranes, as well as semi gantry cranes.

2. Hydroelectric power station gantry crane

Mainly used for starting, restarting, and closing gates, it can also be used for installation operations. Lifting capacity of 80-500 tons, with a small span of 8-16 meters; The lifting speed is relatively low, ranging from 1 to 5 meters per minute. Although this type of crane cannot be used for frequent lifting, it requires a large amount of work after use, so it is necessary to increase the level of operation appropriately.

3. Shipbuilding gantry crane

Suitable for assembling ship hulls on countertops, with two permanent crane trolleys: one with two main hooks, running along the track of the flange on the bridge frame; The other one has a main hook and a secondary hook, which flip and lift large ship sections on the track of the lower flange of the bridge. The general lifting capacity is 100-1500 tons, with a span of up to 185 meters, a lifting speed of 2-15 meters per minute, and a micro movement speed of 0.1-0.5 meters per minute.
