Patent ID: 6981824

Claim:
A sling-traverse device for massive object lifting system providing the elevation of a solid over size and over weight construction comprising an arch-shaped traverse including a shackle on each side of the arch, and wherein each said shackle comprises a slot along longitudinal axis of said traverse of said sling-traverse device; two levers on each said side of said arch rigidly connected to each other in their front lower portion by a stiffener and by a resting girder, and wherein each of the levers includes a pushing spiral spring located on the back side of said each of the levers, and wherein said pushing spiral spring comprises a spring holder on each end of said pushing spiral spring; a directional finger housed inside said pushing spiral spring and connected by an upper side to a spring hinge, which is connected to a spring upper bracket of the appropriate shackle, and by a lower side to a director, which is connected to a spring lower bracket of the appropriate lever; a stopper, providing a limitation of the clockwise movement of said two levers and wherein said stopper is rigidly connected to a H-girder-corbel of said solid over size and over weight construction; a strengthening rib housed between said two levers; a finger-hinge appropriately coupling said two levers and said strengthening rib between said two levers with the appropriate shackle; a traverse connector, comprising a traverse flange, a lower portion of which is by a traverse hinge coupled with said traverse, and a sling flange, an upper portion of which is intended for coupling with the lifting system, and wherein the opposite sides of said traverse flange and said sling flange are rigidly connected to each other.
