Description

Technical Field

[0001] This utility model relates to the field of crane accessories technology, and more specifically to a highly stable crossbeam mechanism for a gantry crane. Background Technology

[0002] Gantry cranes are a variation of bridge cranes. Their metal frame is portal-shaped and consists of a main beam, two legs, and ground rails. They are mainly used for loading and unloading heavy cargo in open-air freight yards, ports, and other similar locations.

[0003] The existing gantry cranes have a one-piece molded crossbeam, which is generally I-shaped. The lower horizontal edge of the crossbeam is used for the movement and positioning of the crane's traveling mechanism. Under long-term pressure and sliding friction, the lower horizontal edge of the crossbeam is prone to deformation or wear. During maintenance, it is necessary to grind it to restore its smooth state, which is relatively inconvenient. Utility Model Content

[0011] As a preferred option, for connection and positioning, the vertical side of the middle part of the main body of the crossbeam is provided with a groove that matches the reinforcing rib.

[0012] As a preferred option, to improve strength, the reinforcing component is made of either austenitic stainless steel or weathering steel.
