摘要

The height-adjustable support, particularly with hand crank is for a semi-trailer, having a segment rolling on a foot-plate at the bottom end of the extensible portion. The plate and segment are coupled together by a rubber component. This component consists of a buffer block (25), contained in a cage (24) fixed to the foot-plate (17). The segment (22) has a bar fixed to it (28), extending inside the cage and engaging with the block. This works in a guide (27) fixed to the plate or cage, and distorts the block when the segment rolls on the plate.
