Rail type container crane is a gantry crane mainly used for container loading and unloading, handling and stacking in container railway transfer yard and large container storage and transportation yard. It consists of the main beam, rigid and flexible door legs, running car, lifting mechanism, vehicle running mechanism, electrical system, operating cab and so on.

The working principle of rail type container crane is: when the container needs to be loaded and unloaded or transported, the operator controls the cart in the driver's room along the track to move smoothly to the target location, and then controls the cart along the main beam to move above the container, and then controls the lifting mechanism to lift or lower the container. The lifting mechanism usually adopts automatic locking device or telescopic arm fork rod to grab or release the container. In order to ensure the safety and stability in the process of lifting, the rail container crane is also equipped with anti-roll device, windproof anchorage system, anti-collision system and so on.

Cantilevered rail container gantry crane: The structure of this crane is simple because the container does not have to pass through the gantry space. Its car running speed is low, generally do not set the anti-roll device. If the user wants to reduce the intensity of operation and increase productivity, the rolling reducer can be installed.
Cantilevered rail container gantry crane: The structure of this crane is complicated because the container must pass through the gantry space. Its car running speed is higher, generally equipped with anti-roll device. It can be cantilevered on either side or side to accommodate different yard layouts.
Double cantilever type: The main feature of double cantilever type crane is that there are cantilevers at both ends of the main beam, which can be operated inside and outside the track, suitable for railway transfer yard and wharf. Large lifting weight, generally 30-60 tons; Wide range of operation, can cover both sides of the track container yard; Can realize multi-layer, multi-column container stacking; Can be used in conjunction with ship-to-shore container crane.

The working level of rail type container gantry crane is generally A6 or A72, which is suitable for port, railway freight yard, wharf and other occasions requiring large tonnage, large span and high speed.
The performance of different types of rail container gantry crane is also different. Generally speaking, the double cantilever type has the largest lifting weight, but the most complex structure; The single cantilever type has the second highest weight, but the structure is simpler. The cantilevered type has the smallest lifting weight, but the simplest construction.
