Claims

[Claims for Utility Model Registration] (1) A cable carrier rail is provided on the upper part of the outer surface of the crane girder, and a plurality of cable carrier rails are provided on the cable carrier rail to support power supply cables at predetermined length intervals. In addition to movably attaching the cable carrier, a top cable carrier supporting the hoist connection side end of the power supply cable is movably provided, and the cable carrier is attached to the hoist movably provided along the lower surface of the crane girder. 1. A power supply device for a hoist in an overhead crane, characterized in that a tension arm is erected along the outer surface of a crane girder, and the top cable carrier is connected to an upper end of the cable carrier tension arm. (2) A cable carrier tension arm is pivotally connected with an axis facing the hoist movement direction, a lower connecting member is erected at the upper end of the cable carrier tension arm, and an upper connecting member is attached to the top cable carrier. 2. The power supply device for a hoist in an overhead crane according to claim 1, wherein the upper connecting member and the lower connecting member are fitted so as to be vertically expandable and contractible.
