Objective: To provide load zone support, stability, and reliability in the transfer point
with limited access and to be able to service the impact rollers in the future quickly, easily,
and with minimal effort.
Challenge: The challenge was to be able to remove and to replace the impact rollers in
this tail section with access limited to only one-side, while providing an easier alternative
to servicing them in the future. Many of the existing impact rollers had already failed.
Some were stuck, worn flat, shafts broken, and some were even missing. These impact rollers
were at a 10° trough, like many of the tailpiece style sections, where changing one of the
impact beds was very difficult. The ‘off’ side of the transfer was blocked by a concrete
footing or pillar. Any servicing that needed to be done on this side was cumbersome and
in some cases depending on the problem, impossible.
