<p>A hoisting arrangement for use with hoisting cranes for handling and lifting loads which are held together by two separate wires includes a support unit which has gripping members with at least four lifting heads arranged iin pairs and each provided with a single gripping member. The gripping members are movable in the longitudinal and in the transverse directions of the support unit, and are caused, when the load is gripped, to slide against the load in opposite directions in the longitudinal direction of the support unit in order to grip in pairs under one wire each, and thereafter to move in pairs outwardly away from each other in the transverse direction to the support unit towards the sides of the load.</p> |
