Truss is a flat or spatial structure consisting of straight rods generally having triangular elements. Under the action of load, the truss bar is mainly subjected to the axial tensile force or pressure, so that the strength of the material can be fully utilized. When the span is large, the material can be saved compared with the solid web, the self-weight and the rigidity are reduced, so it is suitable for load-bearing structures and high-rise structures with large spans, such as roof trusses, bridges, transmission line towers, satellite launch towers, hydraulic gates, cranes, etc.

L type leg single girder gantry crane is featured by light deadweight, light wheel load and reliable performance. L type leg single girder gantry crane apply to general loading and unload and lifting and handling work in open freight storage and along the railways.
Compared with the MG double girder gantry crane, L type leg single girder gantry crane has advantage in structural when transporting long items over the span without space constraints. In addition, due to the structural characteristics of the L type leg single girder gantry crane, the height of the whole product is reduced and the cost is saved in the case of the certain height. The weight is also lighter and the wheel pressure is smaller under the same circumstances.
Given certain lift height, the overall height of L type single girder crane is reduced out of its structural features. As a result, the cost is lowered. L type leg single girder gantry crane is applied to general materials handling service in outdoor freight yard or along railway lines, such as loading, unloading, lifting and transferring work.

Application of the single girder gantry crane

Single beam gantry crane has three control methods: ground (floor) control, remote control and cab control. The ground control, as its name implies, is that the crane can be operated on the ground. The ground operation can be divided into two types currently: the wired ground operation and the wireless ground operation. In the first mentioned of two, the operator controls the crane on the ground by connecting crane’s control line and operating handle. The latter mode of crane is that the operator controls the crane on the ground through the remote controller.
The main components of the single beam gantry crane include: electric hoist, metal structure, trolley traveling mechanism, electrical appliances, main beam, supporting legs, cross beam, crane drive device etc.

The single beam gantry crane is a regular crane widely used as open ground and warehouse to load, unload and grab materials. It has a controlling methods: ground controlling and room controlling. It complies with the relevant regulations of the general gantry crane GB/T14406-1993 and GB5905-86.
Under normal circumstances, if the lifting weight is below 50t and the span is within 35m, there is no special use requirement, so single main beam type should be your best choice. If the door leg width is required to be large, the working speed is high, or the heavy parts and long pieces are often lifted, the double girder gantry crane should be selected.

Features of the single girder gantry crane

A(MH) type single girder gantry crane

A(MH) type single girder gantry crane equipped with steel wire rope hoist, hoist traversing under the main girder, which type has strong box and is suitable for indoor and outdoor use. Crane can be designed with two side cantilever, one side cantilever or no cantilever.

Truss type single girder gantry crane

Truss Type single girder gantry crane’s main girder and support leg both with truss type, it is more suitable for open area,can bear strong wind pressure. This type can be design with full truss type or main girder with truss type, support with box girder or on the contrary, equipped with steel wire rope hoist, hoist traversing under the main girder.

L Type single girder gantry crane

L type single girder gantry crane leg is ‘L’ type, is it more convenience for large size goods from middle position move to cantilever without any dimensional limit of support leg. L type single girder gantry crane can equipped with two type lifting mechanism, one is steel wire rope hoist, hoist traversing under the main girder, the other one is trolley, trolley traversing on the main girder.
