FIELD: mechanical engineering; lifting facilities.

SUBSTANCE: proposed lift contains base with fitted-on extension-type mechanism formed by structural members. Each member is made in form of holding X-shaped frame. Drive mechanism is coupled with frames of structural members and made in form of pulley block whose flexible members is connected by one end to drum of drive mechanism, and second end is secured on base. One end of each structural member is secured on base in cylindrical joint, and roll engaging with base is arranged on second movable end. Block and two more blocks are arranged on base at cylindrical joint of each structural element member on the same end.
