Bryant Telescoper provides conveyor adjustment

Sold in the UK by sole European factory representatives RA Rodriguez, the Bryant Telescoper range has important design and performance benefits.
The tension adjustment of the S2 conveyor at the sinter plant at Corus Redcar was proving increasingly difficult for the maintenance engineers due to harsh environmental conditions and challenging maintenance schedules.
The problem was addressed during a planned plant shutdown but the team encountered considerable problems releasing tension on the tail end in order to replace the conveyor belt.
Not only did the remedial work take excessive time but the poor condition of the adjusters meant that insufficient tension could be applied to the new belt.
The Corus site at Redcar produces circa 3mt of steel per annum facilitated by extensive materials handling systems, which requires regular replacement of conveyor belts.
This is an expensive and time-consuming business that is made worse should the tail end adjustment not be released quickly.
Investigations into alternative tension adjustment mechanisms led Corus engineers to a product that is widely used on mobile crusher conveyors in the UK and on fixed plant conveyors in the US and Canada, the Bryant Telescoper, and it was a move that was to prove a big success.
The adjustment thread in these units is fully enclosed and protected.
Also, unlike alternatives, they feature an Acme thread that is more robust and less prone to 'picking up', a problem that can result in damage or seizure.
Having inspected the conveyors deemed to be the most critical at the time, the RA Rodriguez application engineer was easily able to select the appropriate Telescopers based on bearing bore dimension or shaft diameter.
Confirmation of the bearing bolt hole distance was all that was needed to ensure a good fit.
For five conveyors 'top mount' models were selected in preference to the 'bearing plate' alternative and a standard 36in stroke specified.
The S2 conveyor was fitted with a similar Telescoper model but called for a non-standard 48in stroke; longer strokes are also available.
This request was easily accommodated by the manufacturer Bryant who is also able to supply to suit larger bearings than its 6in standard highest.
In less than two hours the Telescopers were installed and S2 was ready to run.
All the Corus Telescopers have been installed to ensure easy access to the adjustment points enabling the conveyors to be tracked while running.
Recently a belt was changed on one of the original conveyors to receive a Bryant Telescoper and the saving in plant down time was significant.
