What Is the Gantry Crane
2014-04-17 15:50
Gantry crane is a kind transformation of bridge crane. It can be devided into ordinary gantry crane, shipbuilding gantry crane, hydropower gantry crane, container gantry crane ,and so on. Container gantry crane is the most common, especially at the harbour, it is mainly used for outdoor freight yard operation, goods yard, laden in bulk operation, and so on. Usually, container gantry crane is uesd for container terminals, staying-time of quay wall container transport bridge are discharged from the ship then to the yard.
What is the gantry crane? From an overall perspective, it is the level of bridge set on two legs that form a door frame, so its metal structure is looks like the frame of the door-shaped. Bearing the main girder grantry crane is install two supporting feet, and these two feet can be walk on the track which is on the ground directly. In addition, hoisting mechanism of gantry crane, car running and bridge structure is the same as bridge crane. So the both ends of the bridge can be without the cantilever; can also be one end has cantilever or both ends have cantiever in order to expand the scope of the job.
Hence, gantry crane manufacturer put it divide into two categories when they manufacture gantry crane. One is the sigle grider gantry crane, this kind of structure is often chosen by site restrictions, it is very conveninence. The other is the double grider gantry crane, this is the most commom structure form, because it includes a large many of advantages of gantry crane.
These advantages which are the high space utilization, the large range of operation, adaptation of widely and the high universality and so on. Therefore, the structure of the force of double grider gantry crane and the area of effective utilization is reasonable. In addion, the ends of grantry crane can be overhanding cantilever griders, and the stability is very good, the wind resistance performance is also good, what's more, the cost of maintenance is low. The use of the gantry crane greatly reduces the loading and unloading workers labor intensity, it also improves the workers operating conditions,production capacity of loading and labor production rate and so on. It is the key to the packaging construction quality and efficiency of hoisting equipment..
No matter what's the form of the gantry crane, in general, the structure of the gantry crane is consist of three parts that is mechanical parts, structural parts and electrical parts. Furthermore, it has very strict requirements for the operators, for example, they should be familiar with the purpose of the gantry crane, equipment operating methods, the lifting capacity, and maintenance of knowledge, etc.
