Abstract

The system uses an endless cable system. The lower part of a tower crane (1) is carried on a chassis (2) carried on bogies (3) with rollers (4) running on rails (5). It is ballasted by blocks (6) and (7). A stopping and moving device (40) is mounted under the chassis and parallel to the track. It has a T piece (41), with one branch vertical. Attached to the horizontal part are two cables (42) and (43), the ends of these being fixed to a plate (46), running in pulleys (44) and (45) to each bogie, movement of which is restricted by stops (47). The centrally placed stop (41) can contact stops (47). This brings into effect cable (48) and counter weight (16) and brings the crane to rest.
