Abstract
A universal safety device includes, in one embodiment, a cross bar frame and, in another embodiment, a flat platform. Cables extend through the frame or platform, with gripping brackets at the lower ends of the cables configurated and dimensioned to secure lower gripping surfaces of an item to be lifted or moved, such as the lips or lifting rims, or lower recesses or indentations typically provided of sand-filled inertial barriers or crash cushions. Locking members are provided for maintaining the brackets in engagement with the lower gripping surfaces of the items to be lifted and a girth cable or belt is placed around the item to be lifted which circumscribes the downwardly depending cables to prevent accidental release thereof during lifting or movement.
Claims16
Universal safety lifting device for lifting items having upper bearing surfaces and lower gripping surfaces, the device comprising support means;
- a plurality of cables depending downwardly from said support means and defining lower free ends;
- a frame having a lower bearing surface and a plurality of holes for passage of each of said plurality of cables through said frame to dispose said lower free ends of said cables below said frame;
- engaging means attached to said lower free ends of said cables for engaging the lower gripping surfaces of the item to be lifted, the position of said frame being adjustable in the vertical direction and angularly tiltable in relation to the horizontal by passage of selective lengths of said cables through various ones of said frame holes, whereby after each engaging means has engaged a lower gripping surface of the item to be lifted said frame can be adjusted in relation to said cables to securely position the lower bearing surface of said frame into abutment against the upper bearing surface of the item to be lifted;
- and locking means for locking each cable in relation to each frame after the length of each cable has been adjusted to maintain the item to be lifted in abutment against said frame, whereby the raising of said frame safely lifts the item secured to said frame by said cables.
