PROBLEM TO BE SOLVED: To prevent falling of a load-carrying platform even if a wire rope is cut.SOLUTION: A stationery component of a safety apparatus is fixed to a load-carrying platform which is moved along a rail having plural steps. A movable component is moved in a first direction with respect to the stationery component by a tensile force of a wire rope attached to one end of the movable component and is locked on a part of the stationery component. When the tensile force of the wire rope is released, the movable component is moved in a second direction with respect to the stationery component and is locked on a part of the stationery component. A safety bar is rotated so as not to cross a step viewed from a direction of movement of the load-carrying platform in linkage with movement of the movable component in the first direction, and is rotated so as to cross the step viewed from the direction of movement of the load-carrying platform in linkage with movement of the movable component in the second direction.SELECTED DRAWING: Figure 2

    【課題】ワイヤロープが切れても、荷台が落下するのを防止する。【解決手段】安全装置の固定部材は、複数のステップを有するレールに沿って動く荷台に固定される。動部材は、一端に取り付けられるワイヤロープの引張力により、固定部材に対し第1の方向に移動して固定部材の一部に係止し、ワイヤロープの引張力が解除されると、固定部材に対し第2の方向に移動して固定部材の一部に係止する。安全バーは、動部材の第1の方向への移動に連動して、荷台の移動方向から見てステップと交差しないよう回転し、動部材の第2の方向への移動に連動して、荷台の移動方向から見てステップと交差するよう回転する。【選択図】図2
