Norstar offers a Tube Unload that provides ease and safety in operation. The Tube combines with our permanently installed Gear-Driven Sweep. Both the Unload and the Sweep are operated by a single motor and controlled at the Power Head, providing a safe operation with no need to carry a sweep in and out of the bin.
CAPACITY (BPH) ► Tube: Up to 8,170 Sweep: Up to 4,600
Norstar's Tube Unload System features a permanently installed gear-driven sweep that is engaged by a shifting lever located at the Powerhead of the Tube. The Tube flighting drives the sweep through a double gearbox with the whole unit being powered by a single motor, providing excellent operational efficiency.
Norstar Tube Unloads are largely pre-assembled at our factory prior to shipment with no complicated parts to assemble on-site, providing a simple and efficient installation.
GREATER CAPACITY & FLOW
Features like our Widemouth Center Sump and our Advanced Sweep Flighting ensure high performance take-out during unload by promoting better grain flow and capacity.
Norstar uses an innovative auger fighting that features a thicker outer edge that allows you to move up to 100 BPH more than traditional fighting. The thicker edge also increases the auger's lifespan by over 50% (8" models and up).
WIDEMOUTH Center SUmp
Norstar Tube Unloads feature our Widemouth Center Sump. The extended width of the center sump maximizes 360° grain flow as the sweep circles the bin, providing greater capacity at the initial gate.
The SureGrip™ is Norstar's exclusive gear reduction wheel that provides increased sweep traction with its 18" vulcanized rubber design. With a 16:1 gear reduction, the SureGrip™ ensures positive traction and forward movement of the sweep into the grain.
rack & pinion gate controls
Open and close gates efficiently with Norstar's crank system. Located at the Powerhead of the unit, the two gate controls allow the operator to open the center gate separately and the intermediate sumps as one.
Norstar offers an Electric or Hydraulic Powerhead configuration for its Tube Unloads. The Powerhead features a swing-open Belt Gaurd for easy service access. The quick-detach motor mount enables easy movement of the motor from one unit to another.
Norstar's Inclined Powerhead elevates the discharge at a fixed angle, allowing you to fit various intakes under the Powerhead. The distance between the center of the discharge and the ground is 20 11/16"
Norstar's Vertical Powerhead allows you to unload your grain directly to a truck from the bin. Available for 8" and 11" models, the Vertical Powerhead is offered with a standard 119" Vertical Discharge. Custom discharges are also available.
CUSTOM SUMP CONFIGURATIONS
Norstar offers custom sump configurations upon request. Emergency sumps can be utilized to increase grain flow and prevent plugging.
Norstar's Clump Breaker is attached to the sweep gearbox and effectively breaks up grain clumps during gravity unload at the center gate.
