Background story – general explanation of circumstances: Ships carrying bluestone are off-loaded at high speed 3 times per month at very high belt speed. When not used for ship unloading the conveyor is operated at normal speed to transport granite rock (Bluestone) material within the quarry. The maximum life of previous belts was 2 years. After fitting an UsFlex 1000/2 RS belt, belt life has more than doubled and has required significantly less maintenance. After 4 years in operation, the 8mm top cover has only worn by 2mm.
