Storage with vertically movable receptacles for bulk goods

摘要

The receptacles (11) are stacked one above another with their holders (10) in the form of forks extending from travelling carriages (6) which are driven up and down a column (2) by a chain (13) passing over a sprocket wheel (14) to a counterweight. (15). The sprocket wheel is driven by an electric motor and self-arresting worm gear so that carriages with loaded receptacles cannot fall under their own wt. in the event of any failure of the motor-braking arrangements.
