Double Return Tru-Trainer
Para la alineación del lado de retorno de la banda. El TRU-TRAINER de retorno-doble plano fue desarrollado para acomodar la fuerza excesiva que se presenta en el caso de cobands Conveyor anchas y con grandes cargas.
Se diseñó un mecanismo de pivoteo central externo, obviando la necesidad de un rodillo único y grande, y permitiendo alcanzar una rotación concéntrica y equilibrada. Por obvias razones, ello aumenta la vida útil de los rodamientos y brinda un sistema de alineación muy rápido y eficaz.
Two separate conical rollers are mounted on the pivoting mechanism, which can be replaced individually as they are worn out. The same differentiated and successful features of TRU-TRAINER flat return were incorporated into the TRU-TRAINER de retorno-doble plano.
Benefits:
- Designed for high-speed transporters / PIW. It operates in dry, wet and aggressive mining conditions.
- Velocidades superiores a 4 m/s y/o tensiones superiores a 1500 PIW.
- Acomoda fuerza excesiva. Para bandas anchas y cargas pesadas.
- With mends adjustable to any conveyor system.
- The rollers can be replaced individually.
Principios de operación:
- The beauty of this patented system worldwide is its simplicity. The crown-shaped roller has a pivot in the center that rotates laterally on exactly the same plane that uses the Belt.
- As Belt starts moving out of its central axis the chaflanada edge (slightly convex shape, crown type) comes into contact. Due to the lower diameter at the edges a change of forces occurs, making the Tru- Trainer pivot forward to the same side to which the Belt, which naturally makes the next meters of Belt first contact the opposite end by focusing the Belt.
- The Tru- Trainer should be installed with its perpendicular mends at the advance of the Belt, in order to ensure that the pivot turns the roller forward and back instead of up or diagonal.
