This is a model of a Lined Boot Hopper, the design is bolted together and the plastic liner eliminates the wear of the grain against the steel frame of the hopper.
This is a new platform design that attaches to an 8" diameter distributor (the pipe diameter is 8") to allow the maintenance people to safely work on the mechanics within the distributor.
This is my newest design at work, it is a sheet metal shell for a 16" Pipe 4-way Flatback Distributor. Picture that grain goes in the top inlet and can be distributed out any of the four outlets in the bottom. This one is huge, the top inlet is 18" in diameter and the four bottom outlets are 16" in diameter.
