Unloading

Springland Automated U-Trough Unload Systems

Springland unloading equipment is designed for high capacity under floor unloading. Only top quality galvanized material is used on Springland unloading systems. Industrial plating of powerheads and components make finishes last longer and resist the elements. Galvanized and plated surfaces are protected from surface damage.

Springland 11” U-trough unload systems can accommodate 7-1/4” or 9” flighting.

• Rack and Pinion Gate allows for smooth control of gate opening.
  
• Mechanical sweep drive is engaged from outside of the bin. This provides a safe and convenient location for the operator to control the equipment.
  

Advantages

• More capacity
  
• Less power required
  
• Less maintenance
  
• More economical to purchase and to run
  

Springland Sweeps

Gearbox Drive Sweep

• Internal shifting mechanisms
  
• The unload auger motor drives the sweep through a double gearbox
  
• The gearbox can be moved from one bin to the next
  

Electric Drive Sweep

• Enclosed belt guard keeps grain out of drive belts
  
• Quick detach motor belt
  
• Adjustable for 7-1/4” or 9” sweeps
  

Hydraulic Drive Sweep

• Used when electric power is not available
  

Sweep Reduction Drive

Standard with gear box, electric and hydraulic sweep drive.

Reduction Drive with a ratio of 6.25:1 increases safety by slowing the drive wheel down and this in turn reduces wheel wear. For added safety, a stop limits the sweep to one rotation around the bin. An operator must release the sweep stop from outside the bin in order for the sweep to make another pass around the bin.

Positive Drive System

Where dependable, aggressive sweep action is required, a positive drive system replaces the standard friction drive wheel. The sweep flight drives a hydraulic pump and a hydraulic motor is used to rotate a steel spoke wheel on the wall-mounted track. An adjustable relief valve will vary how aggressive the sweep advances in order to keep the sweep fully loaded. The system can be added to existing Springland sweeps.
