Title: Rope pulley monitoring system - has switches emitting signals with each revolution
Inventor: GOLDBAUM HARTMUT
IPC: B66D1/54
Filed: 1974-06-18
Abstract: As the pulley rotates switches are actuated emitting signals. To monitor wear in the pulley groove (5) contacts (6, 9) can be mounted in it, which are electrically connected to each other via the rope as soon as a predetermined amount of wear has taken place. This closes a circuit and emits a signal. Two concentric slip rings (13, 14) can be provided on the pulley for this circuit. Closure of the latter can energise a relay, which in turn closes a holding switch parallel to the contacts and causes a signal to be emitted, typically in the form of a flashing light. Pulley revolutions can be counted by a cam (36) on it, actuating a switch with each revolution and closing a circuit supplying the counter unit.
