Abstract
The position of a cable used in a lifting or similar machine is checked w.r.t. a guide pulley to ensure that the cable is correctly positioned. A probe operated by pulley movement signals derailment of cable. A cable (1) is guided by pulleys (102) and guide plates (106) fixed to pulley mounting (103) prevent derailment. A central hole (104) enables the pulleys to act as balancing assembly. One pulley (102) is mounted on cylindrical support with radial collar (5) to enable sliding w.r.t. the other pulley (102'). A shaft (7) contacts a blade spring (9) operating against pins (16) to keep pulley in contact with cable. A detector (20) signals when no load is applied to pulley thus signalling a derailment.
