Abstract
A load-retaining apparatus including a pallet floor having an upstanding cage mounted thereon for receipt within of a load carried on such pallet floor. A horizontally projecting retainer is provided for resting on such load to hold it captive and is carried from such cage by means of pivotable lifting arms coupled with a hoisting device in such a manner that hoisting of the cage causes such arms to rotate and automatically lower the retainer onto such load. When the pallet subsequently comes to rest on the ground and tension is taken off this hoisting device, the arms are biased to their retracted positions to raise the retainer off such load.

Load-retaining apparatus comprising:
- a pallet floor for receiving a predetermined load;
- a cage mounted on said pallet floor;
- a horizontally projecting vertically shiftable retainer for resting on the top of said load to hold it captive on said pallet floor;
- lifting arms pivotally mounted on their respective one extremities from said cage and formed on their opposite extremities with respective free ends;
- connectors connecting said free ends with said retainer;
- retraction means normally retracting said lifting arms to their retracted positions with said free ends thereof holding said retainer elevated from said load;
- a hoist device liftable to lift said pallet floor;
- and
- actuating means connected between said hoist device and lifting arms and operable upon hoisting of said hoist device to overcome said retraction means to rotate said lifting arms to lower said free ends to lower said retainer onto said load.
