Abstract

The invention concerns a means (1) for upward displacement of a load up a vertical post (3) comprising a guiding mount (4) engaged around the post (3) and supporting the load to be displaced and a motor assembly for displacing the mount (4) up the post including a vertical rack (6) integral with the post (3) or formed therein and consisting of: a speed reduction unit integral with the guiding mount, comprising a rotary input shaft coupled to a motor component and a rotary output shaft whereon is blocked a toothed gear; a chain (11) with articulated links and travelling rollers, meshed on the toothed gear (10) whereof each link on one of the flanks bears at least one tooth (12) designed to co-operate shape-interlocked with one of the teeth of the rack (6); a plate-shaped chain guide (13) of constant thickness, including a guide path whereon run the rollers of the chain, the chain guide path being formed on the edge of the plate, and the flanks of the chain links being urged on either side of the path and of the plate; at least on guide roller being urged to press against the post on the latter's surface opposite the rack, said guide roller being mounted on a shaft (15) integral with a support structure fixed to the mount.
