FIELD: mechanical engineering; lifting and transporting machinery. ^ SUBSTANCE: proposed crane contains bridge resting on end beams along which load trolley moves. Mounted on frame of trolley are trolley travel motion drive and system of sheaves, load lifting and lowering mechanism drive stationary mounted in area of end beam, and traction member with hook hanger. Load trolley carriers load trolley travel motion drive, and load lifting and lowering mechanism drive is arranged stationary in area of end beam. ^ EFFECT: increased load capacity of crane. ^ 1 dwg |
