LEADING THE WAY
Reduction of Unscheduled down time: Robust by design to reduce failure rate at site.
Engineered for reliability, greater load-bearing capacity, and a longer life span than conventional rollers. Gen 7 is lighter for the longer length roller … where it counts!
Savings on Labour & Replacement
In our experience, CII rollers should last for about 3 times that of a conventional roller.
- Case I: At one port where 30 CII Gen 5, idler carbon steel rollers were installed on 17 October 2012, all of these are still running.
- As at 26 October 2017 the engineer reported 77,550,306 tonnes of coal from 11,533 trains has passed over those rollers:
- Case II: A return roller on a ramp conveyor at a mine site, situated just after end pulley – 120 metres from the ground, generally had to be replaced about every 8-10 days. This would result in significant unscheduled down-time.
Solution: One CII VitreSteel roller was used as a replacement roller. It was found to be still working after 2 years with significant savings, increased productivity, labour and replacement rollers costs. The weakest link in the chain had been replaced. The savings amounted to millions of dollars.
Graph 2019: For the first 5 months the replacement rollers show a continuing downward trend for 4 years. The replacements illustrate the declining purchase of conventional rollers, due to replacement by CII (which have not required replacement to date). The savings are significant.
