Conveyor Belt Tracker Improves Performance, Service Life

Martin Engineering introduces a more effective return belt tracking system that uses high-quality materials for easier maintenance and a longer unit life.

Building on the standard crowned roller, the Roller Tracker uses a ribbed lagging made of durable polyurethane to increase performance and wear life. The roller does not come in contact with the belt edge, which means no fraying and excellent tracking for single-direction or reversing belts. The result is more centered cargo loading, less spillage, and increased safety from the hazards of belt wander, leading to higher productivity and a lower cost of operation.

“Crowned tracking rollers have been around for a while, but we saw design issues that prevented them from reaching their full potential,” said Rudolf Beer, engineering and development manager at Martin Engineering. “After creating a working prototype of the new design and testing it at our Center for Innovation, we discovered that we had truly improved upon the technology and engineered the best tracker of its kind on the market.”

Used for lower tension belts from 20-60 in. wide, running at a speed of up to 984 ft/min, crowned roller trackers have a slightly larger diameter at the center than at the edges. Realignment is based on the basic principle of the belt contacting the raised portion of the roller first (the crown) first.  

When the belt wanders off-center, the assembly tilts to the opposing side and steers it back toward the normal position. By retaining a consistent path on the return side, the belt passes over the tail pulley and enters the loading zone centered, delivering equal cargo distribution and reducing spillage.
