Port transportation occupies an increasingly important position in the world’s economic trade. With the continuous development of global trade, the efficiency of port cargo loading and unloading is directly related to the level of economic benefits. Therefore, the innovation and improvement of port lifting and transportation equipment is particularly important.
The design parameters of a rail-mounted container gantry crane (RMG) are the basis of its performance. These parameters determine the crane’s operating capacity and scope of application. The following is an overview of the key design parameters:
Span: The span refers to the distance between the crane tracks, which determines the crane’s operating range. The width of the yard and the arrangement of containers should be considered during design to ensure that the crane can cover the entire operating area.
Outreach: The outreach refers to the effective reach of the crane’s cantilever, which determines the crane’s ability to operate at the edge of the yard. For cranes that need to handle containers at the edge of the yard, outreach is an important design parameter.
Basic size design: The length, width and height of the main beam should be determined according to the parameters of the crane’s span, lifting weight and lifting height. The strength, stiffness and stability requirements of the material should be considered during the design to ensure that the main beam can withstand various loads during the operation of the crane.
Calculate stability moment: Consider the stability moment generated by the crane’s own weight and the outrigger structure, which is usually calculated by the contact area between the crane outrigger and the ground and the distance from the center of gravity of the crane to the outrigger.
During the design process, the crane’s outriggers and tracks should be arranged reasonably to improve the overall stability and load-bearing capacity of the crane.
