FIELD: mechanical engineering; materials handling facilities; equipment for lifting long heavy-weight objects in vertical position. SUBSTANCE: mechanism has lifting hydraulic cylinder one end of which is hinge-secured on frame, flexible tie installed between long object and frame, movable support with guides installed longitudinally on frame for engagement with movable frame which mounts object-to-frame hinge connection and on which one end of flexible tie is secured. Other end of flexible tie is secured on lever hinge-mounted by one end on frame. Other end of lever is mounted on slider located in slots provided along long object. Other end of lifting hydraulic cylinder is hinge-secured on lever. EFFECT: reduced maximum length of lifting hydraulic cylinder, enhanced stability of long object in vertical position. 2 dwg |
