Abstract

A hand operated overhead working platform has a wheeled trolley with uprights between which the cage travels, a hand operated winging gear incorporating a worm drive and ratchet mechanism being attached to one end of the cage, so that the cage is lifted by cables passing over guide pulleys attached to the trolley uprights, one strand of the lifting cable running horizontally underneath the cage. Vertical members forming the corners of the cage carry upper and lower pairs of guide rollers which travel in C shaped vertical guides forming part of the corner uprights of the trolley. The cage has a protective frame around it with a door at the centre. The cage also carries swinging arms with hooked ends which engage cross members on the trolley uprights, acting as a safety device to prevent the cage from descending.
