What is gantry crane

Gantry crane is a kind of bridge crane with horizontal bridge arranged on two legs to form a gantry shape. The crane runs on the ground track and is mainly used for handling and installation in open storage yard, dock, power station, port and railway freight station,its load capacity from0.5ton to 500ton,Shengqi Group,one professional manufacturer in gantry crane field.

What mechanism does the gantry crane include ?

It includes lifting mechanism trolley and crane running mechanism and bridge structure of gantry crane in fact, it is similar to bridge crane. Due to the large span, the crane operating mechanism is mostly driven separately

In order to prevent crane from skew operation and increase resistance, even accidents. The crane trolley of gantry crane runs on the bridge, and some trolley is a jib crane. The outriggers on both sides of the bridge are generally rigid legs; when the span is more than 35 meters, one side is usually rigid legs, while the other side is connected by spherical hinge and bridge, which makes the gantry become a static and determinate system. In this way, the additional stress caused by lateral thrust under the action of external load can be avoided, and the longitudinal temperature deformation of the bridge can be compensated, In order to prevent sliding or overturning under the action of strong wind, the wind meter and crane rail clamp interlocking with the operating mechanism are installed. The bridge can be without cantilever at both ends; it can also be cantilever at one end or cantilever at both ends to expand the scope of operation. Half gantry crane bridge has legs at one end and no legs at the other end. It runs directly on the high platform
