A large hard rock gold mining facility recently performed a scheduled inspection and maintenance on one of their CAT 793D haul trucks. This bed was removed from service due to the alloy steel ahead of the SA1750CR Premium Chromium Carbide Overlay Plate tail section needing to be replaced. This truck had been utilizing the same SAS Premium Liner System for 10 years!
During this maintenance, the SAS Global SA1750CR Tail Section Liner only had a few hot spots. These simply required hand overlay via hardface welding, which was done in the field. The back 90" SA1750CR liner was then released back into production for a second time.
The thickness inspection revealed the SA1750CR Tail Section only lost 0.187” (just about half the starting thickness), and the wall liners only show very slight signs of wearafter 65,000 hours of service over the last 10 years!

A large hard rock gold mining facility installed SA1750CR Premium Chromium Carbide Overlay Plate apron feeder liners into their transfer chute system in 2015. Material from the pit is dumped directly into this system from the haul trucks. These liners were just inspected in August of 2020 and all appear to still be in good shape. These SA1750CR Liners have been in service for 5 years and are still going strong!
