<p>A container for mortar or concrete which is suitable to be hooked onto lifting gear, is made from reinforced plastic. The rectangular shaped bucket has integral ribs (5) on the underside which support the container when it stands on a flat surface. The top edge (9) of the plastic container houses a metal tube (10, 11) such that the load in the container is evenly spread over the support frame. The two opposite top edges (3, 4) on the narrow sides of the container have the support tubes exposed at the mid position where the crane hooks are located. Since the container walls are tapered the empty buckets can be stacked inside each other in order to save space.</p> |
