The pipe-layer developed by Liebherr enables significant productivity increase when laying sewage pipes. The pipe is picked up, positioned at the end of a pipe already in place, aligned and inserted into the previously installed pipe in accordance with existing standards using a horizontal ram. The pipe-layer enables quick and efficient installation of pipes of various lengths, diameters, weights, materials and nominal sizes. Thanks to this system, operational safety on pipe-laying sites is raised considerably, since no one is forced to remain in the danger area.
