To provide an elevator drop test device with high safety.SOLUTION: A device 10 includes: an arm 16 capable of being opened/closed; an arm link 19 connected to the arm and opened/closed in association with the opening/closing of the arm; a lower bolt 21 connecting the arm links to each other and vertically movable along a long hole 23 of a main body 11; an opening arm 25 movable between a lock position applying a force for pressing the lower bolt toward a lower part of the long hole and an unlock position not interfering with the lower bolt; an opening lever 30 movable between an operation position being engaged with the opening arm and held at the lock position and a retreat position not interfering with the opening arm, and a lock pin 38 movable between a set position holding the opening lever at the operation position and a release position allowing the opening lever to move to the retreat position. When the opening arm is positioned at the lock position, the arm is allowed to be held at a closing position. When the opening arm is moved to the unlock position, the arm is allowed to move to an opening position.SELECTED DRAWING: Figure 4

    【課題】安全性の高い昇降機落下試験装置を提供する。【解決手段】開閉可能なアーム16と、アームに連結されてアーム開閉に伴って開閉するアームリンク19と、アームリンク同士を連結して本体11の長穴23に沿って上下移動可能な下部ボルト21と、下部ボルトを長穴の下方に向けて押さえ付ける力を与えるロック位置と下部ボルトに干渉しないアンロック位置との間で移動可能な開放アーム25と、開放アームに係合してロック位置に保持する動作位置と開放アームに干渉しない退避位置との間で移動可能な開放レバー30と、開放レバーを動作位置に保持するセット位置と開放レバーの退避位置への移動を許容する開放位置との間で移動可能なロックピン38とを有する装置10。開放アームがロック位置にあるときにアームが閉じ位置に保持され、開放アームがアンロック位置に移動したときにアームが開き位置に移動することを許容する。【選択図】図4
