The gantry crane is a bridge-type crane in which the horizontal bridge is set on two legs to form a gantry shape. This kind of crane operates on above-ground rails and is mainly used for transportation and installation operations in open storage yards, shipyards, power stations, ports and railway cargo stations.
The rail-mounted container gantry crane consists of the main beam, rigid and flexible door legs, operating trolley, lifting mechanism, cart operating mechanism, electrical system, operating cab, etc. According to the yard operation process, the cantilever can be extended in the direction of the single door leg or the double door leg to become a single cantilever or double cantilever model, and if it is not extended, it will be a non-cantilever model. According to the location, storage and transportation process, and loading and unloading vehicles (container trucks or railway vehicles), confirm the selection of different structural methods without cantilever, single cantilever, and double cantilever.
In container distribution areas such as ports and terminals, the use of rail-mounted container gantry cranes is already relatively common. This is mainly because rail-mounted container gantry cranes have the following advantages:
1. The span of the rail-mounted container gantry crane is relatively large. It can generally accommodate 8 to 15 rows of containers stacked in the middle of the span. It can also place multiple lanes in the middle of the span, so that the site space can be better used.
2. Generally speaking, rail-mounted container gantry cranes are equipped with various equipment that are conducive to intelligent control and automated operations, such as storage systems, retrieval systems, positioning systems, etc., plus the use of high-speed organizational designs. , which greatly improves the working efficiency of the equipment.
3. Because the rail-mounted container gantry crane is driven by electric energy, it has certain advantages in reducing noise and eliminating exhaust emissions, and is a more environmentally friendly equipment.
