TENSION APPLYING DEVICE FOR FEED CABLE IN CRANE FOR WAREHOUSE FACILITY

摘要

PROBLEM TO BE SOLVED: To prevent a feed cable from swinging at acceleration deceleration, when a crane travels or a load carrier is elevatably moved. SOLUTION: This crane for a warehouse facility is constituted so that an elevatable load carrier 8 is loaded on a runnable framework, a transfer device is loaded on the load carrier 8 so as to advance or retreat against a shelf line for delivering and receiving a load, a feed cable 16 is fixed to the middle part in the height direction of a mast 9 constituting the framework through a clamp 18, the feed cable 16 transferring to the load carrier 8 is fixed to the load carrier 8 through a clamp 17, and the feed cable 16 is U-shapedly hung down between the clamp 18 of the mast 9 and the clamp 17 of the load carrier 8. A constraint wheel 37 for applying a load to the feed cable 16 at the U-shaped bending part of the feed cable 16 is rotatably engaged with the extreme end of an elevatable frame 33 elevatably arranged on a guide rail 32 provided along the mast 9.
