FIELD: machine building.
SUBSTANCE: invention relates to load-lifting devices used with ship lowering-lifting devices. Crossbar comprises a frame composed of two parallel beams supported by transverse stiffness ribs, stock devices arranged at the ends of the frame. On beams there are shock-absorbers, movable along the length of a coupling frame with handles-stoppers and vertically integrated in the movable couplings, automatic grippers suspended by stoppers to the shock-absorbers, and leading units for fixing ropes-conductors behind stock devices of a lifting object through coaxial channels in shock-absorbers and automatic grippers of the crossbar.
EFFECT: unified and automated crossbar.
