Abstract (en)
[origin: US4251059A] Apparatus for determining reeving of a pulley system including head pulleys on a jib or boom of a crane and reeving pulleys opposite the head pulleys. There is provided a sensor which may be electrically, mechanically, optically or pneumatically operable at some of the pulleys of the pulley system for sensing the presence or absence of the rope at its associated pulley. Each sensor provides a signal which is fed into a decoder module which may be connected to a display unit for displaying the information or a control device for enabling or inhibiting operation of the associated lifting equipment.
