    • An invalid hoist comprises a telescopic mast (11) having a lower part (18) and an upper part (19), power operated means for raising and lowering the upper part relative to the lower part, a lifting arm (12) pivotably connected to the upper part of the mast, the lifting arm having a sling hanger (23) or at least one sling attachment point at or adjacent to one end thereof, and a manually extendible/retractable stay (30) between the lifting arm and the lower mast part. The lifting arm is pivotally connected to the upper part of the mast at a position intermediate its ends and the extendible/retractable stay is connected to the lifting arm on the side of the pivotable connection between the lifting arm and the upper part of the mast remote from said one end of the lifting arm. The stay can be extended, if the power operated means fails with the upper part of the mast in a raised position, to lower a user to a position in which he/she can be released from a sling supported by the lifting arm. It can also be extended, when the upper mast part is in its lowermost position, to move the lifting arm to a storage position alongside the telescopic mast.
    • 无效升降机包括具有下部(18)和上部(19)的伸缩式桅杆(11),用于相对于下部升高和降低上部的动力操作装置,可枢转地连接到 桅杆的上部,提升臂具有吊架(23)或在其一端处或与其一端相邻的至少一个悬挂附接点,以及在提升臂和下桅杆之间的可手动延伸/可缩回的撑杆(30) 部分。 提升臂在其端部之间的位置枢转地连接到桅杆的上部,并且可伸缩的支架连接到提升臂在提升臂和桅杆远程的上部之间的可枢转连接侧 从提升臂的一端。 如果电动操作装置在桅杆的上部处于升高位置的情况下失败,则可以延长停留时间,以将使用者降低到能够从提升臂支撑的吊索上释放的位置。 当上桅杆部件处于其最低位置时,也可以延伸,以将提升臂移动到可伸缩桅杆旁边的存储位置。
