ABSTRACT:
Portable, inflatable apparatus which, in a deflated condition, can be manually pushed into vertical spaces between stacked articles and which, in an inflated condition, vertically separates stacked articles sufficiently for insertion between the stacked articles or withdrawal therefrom of the forks of a forklift. This apparatus is particularly suited for handling loads which are stored on stickers or dunnage having a minimal thickness on the order of one inch or less. Typically, this apparatus includes an elongated, rigid framework, an inflatable bladder secured to the framework, and valves for inflation and deflation of the bladder. This framework can either be a rigid skid upon which the bladder rests or it can be a metal frame surrounding the bladder, and between portions of which the bladder is stretched.
