Lifting device for replacement of the anodes in electrolysis cells for aluminum production.

摘要

Module toolholder intended to be used within a lifting, comprising two members of motorized lifting independently: a first body composed of a lifting system comprising at least one cable (13), one or two drums (14) electrically motorized, a hoist (18) at which there is fixed a holder tool being wound said one or more cables (13) on said one or more drum (s) (14), and being forwarded (s ) at the hoist (18), first lifting member designed to ensure the movement of a load hoist level (18) at relatively high speed being said, and in a long career; a second member, of which one of the constituent elements is secured to the end of the or cables (13) of said after forwarding level hoist (18) first body, and comprising means which ensure in cooperation with said hoist vertical displacement under reduced by a limited stroke of a larger load speed.
