The sliding seat comprises a fixed plate and a sliding plate, wherein a plurality of bolt holes are formed in two sides of the fixed plate, a plurality of positioning holes matched with the bolt holes are formed in the sliding plate, and the bolt holes are arranged in parallel along the length direction of the container.

The sliding seat further comprises an oil cylinder deviation adjusting plate, and the moving direction of the oil cylinder deviation adjusting plate and the bolt hole are arranged to form a 45-degree included angle.

Pile hydro-cylinder installs in hydro-cylinder skew adjusting plate bottom surface, the slide can be followed the real board and at container length direction translation, the slide removal can be followed to hydro-cylinder skew adjusting plate, and the direction that the hydro-cylinder skew adjusting plate removed along the slide becomes 45 degrees contained angles with the slide along real board moving direction.

The invention has the beneficial effects that:

the transverse rigidity testing device is suitable for the transverse rigidity testing of containers of all machine types by arranging the transverse and longitudinal rigid oil cylinders, the worm gear screw rod mechanism and the beam rail capable of moving up and down on the portal frame.
