Abstract
1,019,648. Controlling jib-cranes. DEWHURST & PARTNERS, and G. E. MINNS. Nov. 16, 1964 [Nov. 20, 1963], No. 45786/63. Heading B8B. To enable messages to be passed to a crane operator when the load block is out of his sight an electrical signal transmitter 18 is carried adjacent the block and is inductively coupled by a closed loop conductor to a receiver 17 in the cab. A lifting cable 14 forms the closed loop conductor with part of the jib. If a pulley 12a is insulated the receiver may be coupled to the cable adjacent the winding drum through which the loop is completed. The transmitter may comprise a microphone, modulator and power unit. Alternatively a microphone 19 may be connected to the load block by a cable 20. Two-way communication may be readily provided. The crane may be remotely controlled by substituting a control unit for the microphone 19. Power is preferably supplied by dry cells.
