Operation of the shock absorber

The vibro-insulating function is taken over by the hallow rubber spring, arranged vertically and loaded under pressure. With growing tractive force the angles are reduced, decreasing by that way the pressure stress of the hallow rubber spring proportional to the tractive force. So it is getting practicable to introduce high tractive forces (high pre-stressing with heavy tractive work) into the pile-drving and extracting equipment without overloading the hallow rubber spring. Simultaneously to the stretching and retracting work of the hallow rubber springensues a swinging of the lateral pressure plates around the upper flexible joints due to the cables aranged in geometric way. Even with maximal tractive stress the verticle swinging introduced by the pile-drive and extracting equipment is absorbed and not transmitted to the tractive cable of the carrier unit.
