In order to assure a good furnace operation, the furnace pallet cars are inspected and repaired periodically. The costs associated with parts purchase and maintenance represent major factors. The parts most frequently replaced are the wheels, wheel shafts and shaft sleeves.

By combining new materials and improved component assembly, PCR PLUS has particularly focussed on the wear of shaft sleeves. This initiative has resulted in the reduction of shaft replacement and consequently, a reduction in maintenance costs.
