INTRODUCTION TO TRU-TRAC®

The Flat Return Tracker employs a unique and highly effective tracking action, which is non-damaging to the belt and kicks in immediately if the belt begins to drift off centre. Because it does not rely on contact with the belt edge in order to guide the belt, belt edge damage, is avoided. The Tru-Trac has special tapers (similar to a crown pulley) on the outher edges of the tracker, which cause the drum of the Tru-Trac to pivot about an internal, vertical pivot axis. The internal central pivot is perpendicular to the belt and this results in the tracking action always being on the same horizontal plane as the belt. For this reason the Tru-Trac works equally well with reversible and shuttle conveyors.

The Trough Tracker was specifically developed to accommodate the loadcarrying side of the belt. Obviously, due to the troughed nature of this side of the belt, a different tracking configuration was required. Wing rollers were incorporated into the design to activate our standard central pivot system

The Dual Return Tracker was developed to accommodate the excessive forces encountered with wide belts and heavy loads. An external central pivot mechanism was designed, obviating the need for a single, large drum, and enabling a concentric and balanced rotation to be achieved. Obviously , this results in extended bearing life and a very fast and effective tracking system.

Heavy Duty We recommend that you opt for the Heavy Duty version of the Dual Return Tracker in extreme environments. The Heavy Duty construction includes extra strong axels, housings and extra coating on the shell.

You should choose the Heavy Duty construction if the environment is very accidic or if the tracker is exposed to side impacts.

We recommend the Heavy Duty construction if the conveyor falls within two of the Heavy Duty criteria.

Our service engineers are ready to pay you a visit to asses your conveyors in regards to optimising your production.
