<p>A supporting frame for suspending a filled sack from the hook of a crane comprises a rod of substantially triangular shape. The end of the sack adjacent the mouth is gathered, flattened and folded onto itself to define two sack layers. Both layers are laid over a first limb of the triangle that is opposite the apex and a clamping bar having a flanged end is inserted between the sack layers adjacent the fold line with the flanged end resting against a second limb of the triangle.</p> |
