QA140 (S-3)

The QA140 (S-3) is the most compact member of the QA (S Series) Screens is a single screen-box screener that uses the same state of the art design technology to construct a screener for today’s requirements. Perfect for the quarry or recycling operation where durability, production and mobility are paramount.

Key Features/Benefits of the QA140 (S-3):

• Capable of high production rates as machine possesses large screening area, and high frequency double deck screen.
• Modern chassis design ensures in- built machine quality and strength for maximum up-time.
• The machine is powered by diesel hydraulics and is self-propelled on tracks.  It has high ground clearance and generous approach angles.
• Low height allows transport by “Step Frame” trailer.
• Highly efficient 10’ x 5’ stepped double deck screenbox gives high productivity and clean product.
• Unique design spreader plate to spread material across the full width of the screening facility whilst maintaining the velocity of the material particles.
• Rapid ratcheting tensioners give fast mesh changes
• Patented screen box lift mechanism to ease mesh change.
• Three large capacity stockpiling conveyors are fully integrated into the machine.
• High efficiency hydraulic system utilizes Piston type motors to maximize power. 
• Hopper fitted with variable speed belt feeder.
  “Centerfold” Main conveyor maintains correct belt tension in all positions.
• Low main conveyor angle begins at 21.5° to permit movement of free-flowing material. Heavy-duty motor allows slow running with heavy load.
• Optional vibrating grid enables the most difficult, heavy material to be processed.
• Direct drive vibrating grid and screen boxes give enhanced efficiency with minimum maintenance – no V-Belts. 
• Hydraulic walkways deploy in seconds, giving low access height and safe working area for maintenance and mesh change. 
• Remote control of tracking and grid tip functions.
• Effective sealing minimizes spillage and dust generation.
• Steel pipe runs used in hydraulic system give improved temperature control and extended hose life.
• High capacity fuel tank allows increased run-time between refueling.
• Low side conveyor transport position allows easy access for maintenance.

Also available with optional:

• Remote control
• High frequency double deck vibrating grid
• On line shredder
