Powder and Bulk Solid (cyclolift style) unloading lifts. Track hopper has recesses for Code 83 rail to be glued in. Modelers will need to cut an 8″ x 13/16″ slot in their layout to accommodate the track hopper. Base is the same height as Code 83 ties. False pipe in bottom to simulate collection main. Use with our Vacuum/Pressure unit for pumping your dry and bulk solids from hopper door style covered hoppers. Also a great addition to any feed mill or grain elevator.
