DEVICE FOR CONNECTING ELECTRIC PLUG CONNECTOR

摘要

PURPOSE: To provide a very large electric plug/connector which actuates with a crane by combining a device for connecting the electric plug connector by remote operation with a hook-shaped bottom block of the crane. CONSTITUTION: A hook-shaped bottom block 1 of a crane connected to a trolley of the crane by a rope or a pulley device is vertically movable. A second lower plug member 3 related to a first upper plug member 2 of the electric plug connector is connected to a load 10 by a cable 4. This load 10 is a work device such as an impact type screw driver suitable to be actuated by remote operation. The first plug member 2 is electrically connected to a center device by a cable 5 to supply power and transmit control commands.
