PROBLEM TO BE SOLVED: To provide overhead dimension measuring tools and methods that are capable of accurately and simply measuring actual overhead dimensions by one operator.SOLUTION: An overhead dimension measuring tool 30 is provided with: a tool base 40 that is installed at the upper position of a car 10; an advancing/retreating member 60 that can vertically move back and forth with respect to the tool base 40 in a state where the tool base 40 is installed at the upper position, and vertically extends; and a movement blocking/permitting mechanism 80 that blocks fluctuation of the position of the advancing/retreating member 60 relative to the tool base 40 when a force of a prescribed level or more for moving the advancing/retreating member 60 to the tool base 40 side is not applied to the upper end of the advancing/retreating member 60, and permits movement of the advancing/retreating member 60 to the tool base 40 side when the force of the prescribed level or more is applied to the upper end of the advancing/retreating member 60.SELECTED DRAWING: Figure 3
【課題】オーバーヘッド寸法を、一人の作業員で正確かつ簡単に実測できるオーバーヘッド寸法測定治具及び方法を提供すること。【解決手段】オーバーヘッド寸法測定治具30が、カゴ10の上方位置に設置される治具ベース部40と、治具ベース部40を上記上方位置に設置した状態で治具ベース部40に対して上下方向に進退自在であると共に、上下方向に延在する進退部材60と、進退部材60の上端部に進退部材60を治具ベース部40側に移動させる方向の所定以上の力が作用しないときに、治具ベース部40に対する進退部材60の相対位置が変動することを阻止する一方、進退部材60の上端部に所定以上の力が作用したときに、進退部材60の治具ベース部40側への移動を許容する移動阻止許容機構80と、を備えるようにする。【選択図】図3
