Method and apparatus for loading and unloading palletized loads

摘要

A sling for loading and unloading several palletized loads simultaneously comprises two pairs of spreader bars each having a plurality of teeth extending perpendicularly with respect to an elongate dimension of the respective spreader bar. The spreader bars are suspended by pairs of cables from a rectangular frame in turn supported by a plurality of support cables. The spreader bars are carried by the suspension cables so that the teeth project upwardly and inwardly from the respective spreader bar towards the associated bar of the respective pair.
