Hydraulic Safe-T-lip dock levellers provide full-time protection against fork-lift trucks falling off a vacant loading dock. The 130 mm high barrier is an integral part of the dock leveller and stops a 45 kN fork-lift truck travelling at 5 km/h. The Safe-T-Lip barrier is positioned automatically when returned to the stored position after completion of the loading and unloading operation. Safety features include the Safe-T-Lip barrier, automatic return to dock position, velocity fuse free-fall protection, full range toeguards with painted yellow/black warning stripes and a maintenance support strut.
