Pulling machine for unloading and laying railway track
The invention relates to a pulling machine for unloading and laying railway tracks, which moves by means of caterpillar tracks running next to the sleepers arranged on the setting bed, with the rail on the provisional supports arranged on the sleepers. The machine comprises a cabin and two caterpillar tracks and includes, in its rear tractor part, a pulling slide that comprises a tube with fastening elements, said tube sliding horizontally, actuated by a hydraulic cylinder comprising a piston connected to the tube, via three dismountable metal supports provided with teflon elements for facilitating the sliding, said metal supports being connected to steel elements acted upon by articulated arms generating the vertical movement by means of the action of another hydraulic cylinder, always maintaining the pulling direction. The machine pulls the rails without needing an auxillary track, maintaining the position of the track-laying train.
