Abstract

Improved sling, which is specially designed to handle groups of large cylindrical bodies, such as rolls of paper, is essentially characterized because it is constituted from a rigid frame, formed by a frame, preferably tubular and square, two sides of which opposites hang groups of atalajes that subject to flexible clamps, each one of them in approximate form of u, which have to surround the group of cylindrical bodies, to which it is tried to handle presenting the ends of such clamps roldanas for passage of cables which have to be related, for example, to the hook of a crane, it being provided that the tensile stress performed on such cables produces the clamping or clamping of the clamps on the group of cylindrical bodies, for which it is necessary to previously release the branches of a kind of scissors, which at one end are attached to cables hanging from the hook of the crane, at the other is articulated to a crosspiece lying centrally between the opposite sides of the frame from which the beams hang, the crossbar of which is traversed internally or inferiorly; by an axis that at its ends has means-lever to be able to rotate in order to cause the tilting of triggers that are capable of retaining the arms of the scissors.
