Trailing CableTW1/ TW2/ TW3
Application
TW1: Here the cable is drawn vertically from a drum as a drag cable via the load platform. The load platform pulls the cable along as it moves up. During the downwards motion the cable returns to the drum automatically. Our special versions are used at heights of up to about 150 meter.
TW2: For greater heights, a so-called carriage version is employed, in which the cable is fed at the center of the tower, i.e. half the way up.
TW3: Here the cable is guided via a spring-loaded drum. These vertical construction lifts are used during new
construction and renovation work on high buildings. The rack lattice elements are fastened at intervals to the
exterior facade.
