ABSTRACT:
An apparatus is provided for the lifting and manipulation of bulk material containers having at least a pair of externally protruding lips or a peripheral rim. The device has a frame adapted to be engaged by one or more kinds of moving machines, such as a forklift, and has a pair of substantially parallel, forward extending container engagement rails. The container engagement rails each have one or more inwardly directed lips which form a shelf or channel, upon or between which a container is supported and captivated for lifting and manipulation by externally projecting lips or rim. The container engagement rails may be vertically displaced from the machine engagement means to more efficiently utilize the lifting range of the machine, and the container engagement rails may be movably mounted to the frame to aid in handling conainers which have become distorted.
