Abstract: The present invention provides a supporting structure of a maintenance platform. The maintenance platform includes a main plate, a supporting module, a plurality of supporting plates, and a plurality of transverse rods. The main plate is provided on the supporting module. The transverse rods penetrate the main plate in a transverse direction. The transverse rods allow the supporting plates to be connected to both sides of the main plate. With the transverse rods penetrating the main plate in a transverse direction, the supporting strength of the maintenance platform is increased, and the undesired break or bend of the supporting plate is reduced.

Abstract: An invention of a flatbed supporting device is composed of a horizontal plate, a hydraulic cylinder, a supporting device, a fixing holder, a first holder & a second holder where the supporting device is made up of a steel connecting rod and a steel shaft being plugged into a hollow longitudinal casing pipe and a hollow lateral casing pip, which are welded on an assembled device and secured & positioned to a hydraulic cylinder with plural bolts for enhancement of supporting strength and inhibition of breaks in usage.

Abstract: The structure of lay board according to the present invention is composed of a front board, a middle board, and a rear board. Those three boards are pin-jointed by several pivots, one pad is installed on each board and several wheels are installed at the bottom such that the chassis can be easily accessed or a tool can be easily taken while maintaining or repairing a vehicle. Besides, since the lay board is foldable, not only maintenance man can sit or lay on it during maintenance or repairing, but the space for storing is saved as well. The lay board according to present invention is thus a multiple purpose appliance.
