KGHM's copper operations in Lubin and Sieroszowice run some of Europe's highest-utilization underground drill fleets. The RD22U drifters on their development headings accumulate percussion hours at a rate that makes the piston guide's clearance maint...

The RD22U's heavier piston—more mass, longer stroke, higher impact energy than the RD18U class—changes the fatigue arithmetic in Finnish hard-rock operations. At Agnico Eagle's Kittilä gold mine in Lapland, the gold-bearing schist tr...

German tunnel engineers building the Brenner Base Tunnel through the Alps and the Stuttgart 21 rail project underground have a phrase for what happens when overhaul kit components from different suppliers get mixed at service: 'Dimensionsroulette'&md...

The Atlas Copco RD22U steps up from the RD18U in percussion energy class—its heavier piston delivers more joules per blow for the demanding hard-rock formations of northern Sweden's mining belt. That higher energy per blow changes the operating...

A full seal kit for the Atlas Copco RD18U is the only maintenance purchase that directly affects every performance parameter of the percussion circuit simultaneously. The percussion seal determines effective pressure differential per blow. The flushi...

Finland's deep-level mining operations at Outokumpu's old copper belt and the newer gold discoveries in Lapland operate RD18U drifters in formations that combine high UCS with high quartz content—the most abrasive combination a guide piston enc...

Canada's potash mines in Saskatchewan—Nutrien's Vanscoy and Cory operations, Mosaic's Esterhazy—present a different mechanical environment for the RD18U's roller bearing than the hard-rock applications the drifter was primarily designed a...
