PROBLEM TO BE SOLVED: To provide a lifting magnet device enabling an easy measurement of insulation resistance of a power cable and capable of suppressing a generation frequency of a trouble such as a breakage of a control component, in view of a fact that when measuring insulation resistance of a power cable for supplying electric power to a lifting magnet, it is necessary to measure by using an insulation resistance meter after removing an end part of the power cable to be measured, therefore there lies a problem that the work takes time.SOLUTION: There is provided a lifting magnet device, including: a power supply part for outputting electric power; a magnet drive circuit for controlling the electric power from the power supply part; a lifting magnet to which the electric power is supplied from the magnet drive circuit via a cable; current measuring means for measuring the current of the electric power supplied to the lifting magnet; and insulation resistance measuring means for measuring insulation resistance of the cable.SELECTED DRAWING: Figure 1

    【課題】リフティングマグネットへの電力を供給する動力ケーブルの絶縁抵抗の測定は、測定対象の動力ケーブルの端部を外してから絶縁抵抗計を用いて行う必要があり、作業に時間がかかるという問題があった。本発明は上記事情に鑑み、動力ケーブルの絶縁抵抗を簡易に測定することができ、制御部品の破損などの不具合の発生頻度を抑えることができるリフティングマグネット装置を提供する。【解決手段】リフティングマグネット装置であって、電力を出力する電源部と、電源部からの電力を制御するマグネット駆動回路と、マグネット駆動回路からケーブルを介して電力が供給されるリフティングマグネットと、このリフティングマグネットへ供給される電力の電流を測定する電流測定手段と、ケーブルの絶縁抵抗を計測する絶縁抵抗測定手段とを備える。【選択図】図1
