Haul Truck Bed Liner Life Increased by 400%+

NanoSteel Overlay Wear Plate Provides superior wear performance over 500 BHN Q&T plate

Problem: Severe Sliding Abrasion in Haul Truck Bed

At an extreme hard rock mine in the Southwest USA, a fleet of 240-ton haul trucks transport ore from an electric shovel to a primary crusher. During unload, the rear section of the truck bed receives the greatest amount of wear from severe sliding abrasion. A 500 Brinell quench & temper (Q&T) monolithic steel wear plate installed to protect the original truck bed only lasts an average of 12 months.

 

    Solution: NanoSteel Overlay Wear Plate

    A NanoSteel SHS 9700 overlay wear plate was installed in one truck as a side-by-side wear life performance comparison to 500 Brinell Q&T wear plate.

      Result: NanoSteel Wear Plate Provides 400%+ Longer Life

      An ultrasonic inspection of the NanoSteel plate at 48 months showed 40% of the original ¼ in (6 mm) overlay thickness remaining. The NanoSteel overlay wear plate was removed from service after hauling more than 13 million tons in 52 months while 500 Brinell Q&T wear plate was replaced after an average of only 12 months of service. Benefits to the mine include elimination of three sets of wear plate and cumulative manpower hours required for each installation and increases in production and revenue.

      400%+ improvement over 500 BHN Q&T liner

      The NanoSteel weld overlay wear surface is 1/3 the thickness of 500 Brinell Q&T bed liner and remained in service more than 400% longer
