Single Girder Gantry Crane

Single Girder Gantry Crane

Single girder gantry crane is a type of light small gantry crane with a single girder and rail travelling. The single girder gantry crane is designed for generally material handling, with the lifting capacity around 1 to 20 tons, and working class A3, or A4. The specification of the single girder gantry crane is as follow:

Product Type MH

Lifting Capacity 1~20t

Span Length 8~30m

Working Class A3, A4

Ambient Temperature -25~40℃

Components of Single Girder Gantry Crane

Single girder gantry crane is mainly consisted of gantry frame, i.e. main single girder, legs, bottom end beams, lifting mechanism, travelling mechanism, and electrical control. It can be designed with two hanging arms, one hanging arm or no-hanging arm according to client's lifting requirements and application environment.

Classification of Single Girder Gantry Crane

Single girder gantry crane can be divided into box type and truss type.

Box type

The box type single girder gantry crane is a medium sized crane, travelling in track , usually equipped with standard CD MD electric hoist as the lifting mechanism, and the electric hoist traversing along the lower flange of the I- steel of the main girder, which is made of high quality steel plates, such as, C-steel and I-steel.

Truss type

The truss single girder gantry crane differentiates itself with the box type crane in terms of structure construction. The former is made of steel bars and the latter is made of steel plates. The truss gantry crane is much lighter than that of the box type gantry crane and it has high wind resistance.

Application of Single Girder Gantry Crane

Single girder gantry crane is regular crane, designed for general material handling , which is frequently used at open ground, warehouse, ports, granite industry, cement pipe industry, open yard, container depots and shipyards, etc. However, it is forbidden to handle melt metal, inflammable. Or explosive objects.
