[0016] Furthermore, the main body of the inspection table further includes a bracket with a cuboid structure, and legs are fixedly connected to the corner positions of the bracket.

[0017] In the above technical solution, for the bogie crossbeam inspection table provided by the present utility model, the beneficial effects are as follows:

[0018] For the bogie crossbeam inspection table designed by the present utility model, a platform is arranged on the main body of the inspection table.
