Ladder welding machine
The Tunnel Master is used for the manufacture of straight and curved ladders from coil and can be manufactured in a variety of designs, which are custom-made for the customer's technical and economic requirements. In combination with the mesh welding plant the Tunnel Master is your complete solution for manufacturing tunnel segments. The Tunnel Master processes up to four longitudinal wires and positions them and the cross-wires correctly by means of a continuously adjustable spacer. In this way this system facilitates fast, technically refined and cost-saving production of straight and curved ladders from the coil for tunnel segments and similar precast concrete elements.
