Belt Alignment

 

Martin® Screen Tracker

The Martin® Tracker™ provides immediate, continuous precision adjustment of wandering conveyor belts. The Tracker™ works where other belt training devices fail to reduce edge damage, prevent spillage and extend belt life.

Features and Benefits:

  • Keeps the belt in alignment with automatic, continuous adjustments
  • Improved tracking reduces edge damage, spillage and maintenance expense.
  • Continuous precision adjustment of the patented parallel steering/training system keeps the belt tracking properly.

Options:

  • The Martin® Tracker™ is available in 3 models to match the requirements of each application.
  • The Tracker™ is designed for applications under typical industrial material handling conditions.
  • The Tracker™ HD is designed to withstand the stress associated with wider, thicker belts moving at higher speeds and carrying heavier loads.
  • The Tracker™ XHD is engineered to be effective in the most rugged of applications.
 

Belt Support

 

EVO® Slider Cradle

The EVO® Slider Cradle eliminates pinch points where trapped material can gouge or tear the belt and stabilizes the belt's path to improve sealing and tracking. Low-friction UMHW bars support belt edges to stabilize the belt line, eliminating belt sag and bounce. Proprietary "box" design allows each bar too be turned over to provide a second wear life.

Features and Benefits:

  • Like the rest of the EVO® Conveyor Architecture, the EVO® Slider Cradle features track-mounted sub-assemblies. The edge support bars and the center support roller slide into position on the track, making it quicker and easier to install and maintain the cradle.
  • The EVO® Slider Cradle utilizes low friction UMHW bars to support the belt at the outside of the load-carrying area. This stabilizes the belt line, eliminating the sag and bounce that spill material and reducing the risk of catching lumps that can abrade the belt surface.
  • The low friction bars utilize a proprietary "box" design that allows the bars to be turned over to provide a second wear life from each bar. In the center of the cradle, idlers reduce the friction of carrying the loaded belt.
 

Impact Cradle LD

Installed under the belt conveyor loading zone, Martin® Impact Cradles absorb the force of falling material to prevent damage to the belt and structure and to help eliminate spillage.

Features and Benefits:

  • Loading zone cradle absorbs up to 8500 pounds (3856 kg) of force in tough belt loading applications.
  • Adjustable support arms allow precise match to belt's trough angle; eccentric allows 5 degrees of adjustment to compensate for bar wear.
  • Cradle stabilizes belt line to eliminate belt sag and reduce fugitive material.
  • Adjustable arms simplify placement of cradle under loading zone.
  • Matches CEMA "C" and "D" idler profile; Conforms to CEMA Standard No. 502-1998 Bulk Material Belt Conveyor Troughing and Return Idler Specifications.
  • Available for belts from 24 to 48 inches (500 to 1400 mm) wide.
  • Protected by U.S. Patent No. 6,454,083.
 
 
 

Trac-Mount™ Idler

Martin® Trac-Mount™ Idlers utilize sliding frames on a stationary base to provide an idler set that will fit in tight spaces between belt support cradles and allows easy installation and service. Trac-Mount™ Idlers are available with standard or wide base frames and utilize impact or steel rolls in CEMA class A, B, C, D or E.

Features and Benefits:

  • Slide-in frames need only eight inches (203 mm) of width for 6-inch (152 mm) rolls.
  • Slide-out/slide-in roller frames allows idler service without need to raise belt or remove adjacent idlers.
  • Trac-Mount™ Idlers provide proper belt carriage while they stabilize the belt line to improve sealing.
  • Assemblies are supplied with steel or impact rolls from Precision Pulley and Idler.

Custom Engineering

  • Martin Engineering can custom-design Martin® Trac-Mount™ Idlers to meet unique application requirements. Options include steel construction, frames with adjustable angle, and rolls from alternative suppliers or other special needs. Discuss your application with a Martin Engineering representative.

Tail Protection

 

Diagonal Plow

For tail protection on reversing belts, specify the Martin® Diagonal Plow. Hung from brackets on both sides of the conveyor, the Martin® Diagonal Plow floats on the belt surface to remove material without needing adjustment.

Features and Benefits:

  • The durable 80 Shore A Durometer Nitrile rubber blade provides 1.5 in. (38 mm) of wear in service temperatures to 250°F (121°C) and belt speeds up to 900 fpm (4.6 m/sec).
  • Diagonal plow protects pulley in either direction of travel.
  • Plow drops into mount brackets on either side of the conveyor.
  • Blade floats on belt surface and diverts material away for effective tail pulley protection.
 

Durt Dozer™ Plow

The Martin® Durt Dozer™ Plow installs on single-direction belts on the conveyor's return side, just before the belt enters the tail pulley. It sits across the belt at a 45° angle, using its curved blade to remove material from the inside surface of the belt at belt speeds up to 700 fpm (3.5 m/sec).

Features and Benefits:

 

  • Curved plow blade installs at angle across belt to remove material.
  • Turn the two-edged blade over to double the service life.

 

 

VPlow HD

The Martin® VPlow HD is an economical solution for tail protection in medium to heavy duty applications.

  • The sturdy 80 Shore A Durometer Nitrile rubber blade provides a 2-in. (50-mm) wear life at service temperatures to 250°F (121°C) and belt speeds up to 900 fpm (4.6 m/sec). Mounting hardware included.
  • Martin® VPlow HD removes material before belt enters the tail pulley.
  • For less demanding transfer points vplow applications.
 

Tail Sealing Box

To conquer the age-old problem of material spilling off the tail of the conveyor, install the Martin® Tail Sealing Box. Installed on the rear of the chute work, the box uses Martin® ApronSeal™ Skirting and Strip Rubber to create an effective seal to keep material on the conveyor.

Features and Benefits:

  • Seal keeps material from sliding off the belt.
  • Belt motion deflects tail seal to prevent accumulation at back of box.
  • Deflected sealing strip contains rollback without scraping off adhered material.
  • Return material to belt through easy-opening Martin® Inspection Door.
  • Field-welded on chute wall to ensure precise fit.
