To prevent an arm protection plate from being damaged when a coil is lifted by a coil lifter.SOLUTION: A coil lifter 10 grips a coil by inserting a pawl 28, which is provided to protrude inward on a tip of an a pair of arms 27 by closing the pair of arms provided to be openable/closable, in an inner diameter space of the coil. Protection plate guards 36, 37, 38 for protecting each lower end of protection plates 32, 33, 34, which are respectively provided on rear surfaces and side surfaces of the arms, are fixed to arm lower end parts by welding. Inclined surfaces are provided on lower end parts of the protection plate guards. Each of the protection plate guards is provided to be inclined upward with approximately the same angle with an inclination angle of a lower end chamfer part of the protection plate and is mounted such that the lower end chamfer part of the protection plate is fitted into a gap between the protection plate guard and an arm surface.SELECTED DRAWING: Figure 1

    【課題】コイルリフターでコイルを吊り上げようとするときにアーム保護板が破損しないようにする。【解決手段】開閉可能に設けられる一対のアーム27を閉じることにより該アームの先端に内向きに突出して設けられる爪28をコイルの内径空間に挿入して該コイルを把持するように構成されたコイルリフター10において、アームの背面および側面にそれぞれ設けられる保護板32,33,34の各下端を保護する保護板ガード36,37,38がアーム下端部に溶接固定されている。保護板ガードの下端部には傾斜面が設けられる。保護板ガードは、保護板の下端面取り部の傾斜角度と略同一角度で上向きに傾斜して設けられ、保護板ガードとアーム面との間の隙間に保護板の下端面取り部が嵌合された状態で取り付けられる。【選択図】図1
