Box-type Single girder semi-gantry crane
Box-type Single girder semi-gantry crane is a type of light small gantry crane with a single girder and rail travelling. The Box-type Single girder semi-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 Box-type Single girder semi-gantry crane is as follow:
Components of Single girder semi-gantry crane
Box-type Single girder semi-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 Box-type Single girder semi-gantry crane
Box-type Single girder semi-gantry crane can be divided into box type and truss type.
Box type
The box type Box-type Single girder semi-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-type Single girder semi-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.
The Box - type Single girder semi - gantry crane is a common and reliable choice for general material handling. Engineered with a sturdy box - type structure, it's well - equipped to manage diverse items. At open ground, it's a workhorse for construction, easily moving heavy building materials.
Warehouses use it to shift large storage units, optimizing space. Ports rely on it for container handling, and industries like granite and cement pipe production depend on it to handle their bulky products. Despite its versatility, safety must be maintained. Handling molten metal, inflammable substances, or explosive materials is strictly off - limits to avoid dangerous situations and protect workers and property.
