Ramming and traction device

摘要

The device has an exciter cell (1) guided at a guide pole (7) and coupled to an advancing system of the guide pole. The exciter cell is linearly movable by the advancing system. The exciter cell is rigidly connected with guide rails (21). The guide rails are guided at the guide pole and elastically connected with the advancing system by ropes (3, 4). A spring module is designed as a spring package (5) including cylindrical helical springs, disk springs, gas pressure springs, torsion springs and/or flexible springs. An elastic loop is made of glass fiber reinforced plastic material. The ropes are made of glass fibers.
