Abstract
Lifting gear for a filled sack comprises a pair of clamping bars between which the gathered and flattened mouth portion of the sack can be clamped after the mouth portion has been slung thereabout. The bars are in the form of parallel cantilever arms and rotatable about an axis parallel thereto, one of the bars also being displaceable to and from the other bar while remaining parallel thereto.

Apparatus for lifting a filled sack, comprising a frame, a pair of clamping bars about which a gathered and flattened end of the sack is slung, and means for mounting said bars on said frame, the pair of clamping bars being rotatable about an axis parallel to the bars from an initial spaced apart position to a terminal position in which the end of the sack is clamped tight between the bars, one of the clamping bars being displaceable towards the other in parallel relationship, the clamping bars (10, 15);
- (110, 115) being held in their respective mounting means (4, 120, 121) only on one side such that they form parallel cantilever arms, one of said clamping bars moving toward and rotating about the other of said clamping bars during rotation of the bars from the initial to the terminal position.
