ABSTRACT:
In lifting gear for filled sacks, a device for engaging a gathered and flattened end of the sack adjacent the mouth thereof comprises two pairs of tongs. A first clamping bar is disposed at the free end of one limb of each pair of tongs and a second clamping bar, parallel to the first, is secured to two links which are pivoted to the free ends of the other limbs. The gathered and flattened end of the sack is introduced between the clamping bars as the open tongs are lowered, whereupon the links are revolved and the tongs are closed so that the end of the sack is slung about the clamping bars.
