How to select a dumper
As material handling devices, dumpers often perform one simple task they elevate a container and discharge its powder or solids contents into another container or into or onto other equipment. Initially, dumpers were used to reduce manual labor or because they were the only practical way to do the job. Economics played a large part in deciding whether to use dumpers.
Today, worker safety regulations -- initiated by individual employers or local, state, and federal agencies -- often require the use of dumpers, regardless of cost. This article reviews the various types of dumpers used with powder and bulk solid material and provides guidelines for gathering data for dumper selection.
