Abstract

A vertical movable platform is supported by cables (9) and is guided in upwards and downward movements between columns. The cables are connected to a motor for raising and lowering the platform under electrical control. A cable (25) is fixed at one end to one column and by its other end to another column. The cable extends to all the columns and across the platform, permitting a free displacement in translation of the platform, without change of tension. Breakage of a cable (9) will cause change of tension, in response to which the electrical circuit is opened.
