Bin unloading units normally incorporate multiple inlets with slide gates and sweep pivots where needed. The usual choices of drives and elbow combinations are available on the Mass-ter Mover (Mass-ter Flow is horizontal only). Drive-over pit hopper (photo A) with 30°, 45° or 90° incline sections allows for a dump-and-go operation without a costly holding pit. Swing-away hopper (photo B) and portable hopper (photo C) enable you to custom design your handling system.
