Abstract

Scaffold members are erected to produce a mobile platform lift or a goods/personnel elevator. The platforms are provided with two or more vertical screws which engage with a number of pegs set at intervals in the fixed vertical frame members. A reversible geared motor beneath the platforms rotates both screws through a positive mechanical transmission, a method which ensures a very gentle vertical motion and absolute safety in case of electrical failure owing to the irreversibility of the screws. There are horizontal ladder rungs attached to the uprights supporting the screws and enclosing the screws in the form of a cage.
