Bridge crane can be divided into general bridge crane, simple beam bridge crane and metallurgical special bridge crane 3 kinds

Bridge crane is widely used in indoor and outdoor warehouses, factories, docks and outdoor storage yard, etc. Bridge crane can be divided into general bridge crane, simple beam bridge crane and metallurgical special bridge crane 3 kinds. General bridge According to the frame structure bysino hoistthe car, general bridge operation, the structure of the bridge metal composition. Lifting trolley and running institutions by the lifting mechanism, the car and the car frame of three parts. Lifting mechanism including motor, brake, reducer, drum and pulley. Motor through the gear reducer, drive the drum rotation, make wound reel or wire rope from the reel down, to lift heavy things. The car frame is bracket and install the lifting mechanism and car running parts, such as organization frame, usually for welding structure. Gantry crane is generally based on the door frame structure form, the form of main girder, sling for classification. hoist gantry crane used in port.

(a) the whole gantry crane: no overhanging girder, the car in the main span.

(b) a gantry crane: leg height difference, can be used according to the field of civil engineering request.

(c) double cantilever gantry crane: one of the most common structure form, the structure of the force and the area of effective utilization is reasonable.

(d) of single cantilever gantry crane: this kind of structure is often chosen by site restrictions.

According to the main girder structure

(a) single girder gantry crane

The characteristics of the arm crane and bridge crane are basically the same. Can work, over the round ground and widely used at open handling and installation work, such as a door crane, floating crane, mast cranes, crane and deck crane, etc.

Arm crane include lifting mechanism, luffing mechanism, rotating mechanism. Rely on these institutions cooperate with action, can make the weight lifting and handling within a cylindrical space. Arm crane installed on vehicles, or other forms of transport (mobile) tools, thus constitute the arm posture slewing crane operation. Such as auto crane, wheel crane, tower crane, portal crane, floating crane, rail crane, etc.
