Product Knowledge: Atlas Copco COP1838MUX-T & Part 8311124963

The Atlas Copco COP1838MUX-T is a high-performance hydraulic surface drill rig widely used in open-pit mining and quarrying. The part 8311124963 is a critical component in the rig’s hydraulic percussion system, ensuring stable high-frequency impact and long service life. Our alternative part is manufactured from 42CrMo alloy steel, precision-forged, CNC-machined, and heat-treated to HB 280-320, delivering 95 % of OEM performance at 40 % of OEM cost.

Real-World Failure Case & Solution

Equipment: Sandvik D45-C blast-hole drill rig
 Fault: Severe internal leakage in the hydraulic percussion piston (OEM PN 8311124963), causing drop in impact pressure from 210 bar to 160 bar and penetration rate falling from 0.9 m/min to 0.5 m/min.
 Solution: Replaced with Hugeminer alternative 8311124963 (42CrMo, HB 300). After 200-hour field trial in Andes copper mine (altitude 4,200 m), impact pressure restored to 208 bar, penetration rate increased to 0.88 m/min, hourly fuel consumption reduced by 6 %, and part life reached 1,800 hours (OEM 1,900 hours). Total saving: USD 3,200 per rig per year.
