Structural Features of Rubber Tyred Gantry Crane

Beam
The beam is main force component of rubber tyred gantry crane, which adopts box structure. The trolley walking track is built on the two main beams, which has two types: it is build center position of the main beam section, which is called track box girder; it is built on the web of edge of upper flange plate, which is named partial rail box girder.

Door leg structure of RTG crane

Bottom beam structure
Bottom beam structure of rubber tyred gantry crane adopts box structure of uniform section, it is connected with cart by pin roll, and then it connects with ear plate by slab structure. In order to support lateral forces, there is shear block between the bottom beam and wheel balance beam.

Rail mounting of RTG crane
Rail mounting usually uses rail pressure plate form; its installing is very convenient according to adopt T type bolt. There is rubber blanket between the rail and baseboard between the track and the bottom to reduce the impact on the main beam structure, rail adopts seamless joints or welded splice. The crane uses rail and beam welded directly. This forms a good stiffness, and can participate in the force, maintenance-free.

Trolley fame of rubber tyred gantry crane
Trolley frame is I-beam structure and arranged on both sides of the aisle, corners hang platform to maintain pulleys and other components. Some trolley frame laid tall platform, lifting ropes through the platform.
