The LUKAS DUO sliding unit with integrated locking pin as a counterholder enables you to operate the entire work process outside the danger zone without having to move it manually, even with heavy loads. The DUO sliding unit and the roller carriage are equipped with lateral guides to enable straight guidance on the bridge. When moving, integrated sliding plates compensate for the curved movement of the rail vehicles to be moved in. To ensure optimum stability without the cylinders tilting, LUKAS uses connecting rods and roller carriages with smooth-running rollers mounted on roller bearings.
