Abstract

In a hoist system of the kind comprising a mast 4 made from a number of sections which are successively assembled to a desired height, and a hoistable cage 2 guided for movement by guide means on the mast and usable as a working platform for assembling the mast, the cage carries means for sensing undesired discontinuities of the guide means, and switch means responsive to the sensing means for stopping movement of the cage when such a discontinuity is sensed by the sensing means. A switch 12 on the lift, for stopping the lift motor, is operable via a link 40 by the rotation of a pivoted arm 22 carrying a roller 34 which normally runs on a rack 20, when a rack and pinion drive is employed. The switch can alternatively be operated from the cage via cable 48 and link 40, or by a cam rail at the top or bottom of the mast, which contacts a finger 18 extending from the switch. <IMAGE>
