PROBLEM TO BE SOLVED: To provide a counterweight clearance measuring device capable of performing accurate measurement.SOLUTION: The counterweight clearance measuring device includes: a movement amount measurement part 13 for starting to measure a movement amount of a counterweight on the basis of information from a movement amount detection part 8 of a car in the case that an optical sensor 10 fixed to prescribed height in a hoistway in a state of facing a projection surface side of an accessory member of the counterweight is determined to be in an on state; a comparison determination part 14 for comparing the movement amount with the height dimension of the accessory member in the case that an on/off state determination part 12 determines that the optical sensor 10 is in an off state; an input-output control part 11a for causing the movement amount measurement part 13 to continuously measure a movement amount in the case of determining that difference in length between the movement amount of the counterweight and the height dimension of the accessory member is within a prescribed range; and a clearance calculation part 16 for calculating counterweight clearance on the basis of a measurement result of the counterweight measured by the movement amount measurement part 13.SELECTED DRAWING: Figure 5

    【課題】正確な測定が可能なカウンタウエイトクリアランス測定装置を提供する。【解決手段】カウンタウエイトの付属部材の突出面側に対向する状態で昇降路内における所定の高さに固定された光センサー10がオンの状態となったと判定された場合に、乗りカゴの移動量検知部か8らの情報に基づいてカウンタウエイトの移動量の計測を開始する移動量計測部13と、オン/オフ状態判定部12において光センサー10がオフの状態となったと判定された場合に、移動量を付属部材の高さ寸法と比較する比較判定部14と、カウンタウエイトの移動量と付属部材の高さ寸法との長さの差が所定の範囲内であると判定された場合に、移動量計測部13に対して移動量の計測を続行させる入出力制御部11aと、移動量計測部13で計測されたカウンタウエイトの計測結果に基づいてカウンタウエイトクリアランスを算出するクリアランス演算部16とを備えた。【選択図】図5
