The design of overhead monorail crane is different from general structural design because of its loading conditions and its effects. Speed idler type and structure in order to establish the basic parameters of the conveyor design. The web tension flange of the beam force the compression flange to buckle sideways which results in the whole section twisting hence torsional buckling.
The crane beam design software will help you design the following. Design of the monorail beam along with the supports and connections can be an iterative process. 20 of the sum of the lifted load and the crane trolley but exclusive of other parts of the crane As this is a monorail and the hoist.
The initial version of the body structure is simplified then the ANSYS is employed for modeling and meshing. The element size is 10mm and the number of elements is 1653722. Google has not performed a legal analysis and makes no representation.
