To provide a vertically-winding type electric cable reel for feeding power to a suspending tool suspended from a crane in which the dimension of the cable reel, the maintainability, and torque control performance are improved.SOLUTION: A direct drive system in which a reduction gear is eliminated by adopting a multipolar electric motor as an electric motor for generating torque in a winding direction, is adopted for a cable reel RE. The cable reel has a function of performing increase/reduce control of the torque of the cable reel RE based on operation information of a control device for controlling the vertical movement of a suspending tool GB.SELECTED DRAWING: Figure 2

    【課題】クレーンに吊り下げられた吊具に給電するための垂直巻き取り式の電動式ケーブルリールにおいて、ケーブルリールの寸法や、メンテナンス性を改善と、トルク制御性能の向上を図ったケーブルリールを提供すること。【解決手段】ケーブルリールREに巻き上げ方向のトルクを発生させる電動機に多極電動機を採用することにより減速機をなくしたダイレクトドライブ方式を採用し、吊具GBの上下動作を制御する制御装置の動作情報に基づいて、ケーブルリールREのトルクの増減制御を行う機能を有する。【選択図】図2
