摘要

The device (9) has a honeycombed grid (11) welded on its top, and a spring reinforcing plate (8) welded in its center, where the device inclines on right or left at an angle varying from 0 to 20 degrees with respect to horizontal. The inclination of the device is dampened by springs (1) made of stainless steel or steel, where the spring rate of the springs is comprised between 2 and 3 kilogram/millimeter. The compression of the springs is adjustable by a wedge (5).
