The boom swing cylinder on the DD2710 moves the entire B26F boom assembly laterally—repositioning between the left and right sides of the face pattern and covering the full cross-section width that the telescopic extension alone can't reach. In...

The feed swing cylinder positions the TF512 feed beam in the horizontal plane—swinging it left or right from the boom centerline to cover the full width of the development face pattern. In German Autobahn tunnel construction through the Swabian...

The control valve block assembly on the DD2710 is the hydraulic brain of the jumbo—it routes hydraulic flow to every actuator on the rig (boom lift, swing, telescope, feed, rotation, percussion) through a manifold of directional control valves ...

Germany's underground coal and potash mining—K+S Group's Werra potash mines in Hesse, and RAG's remaining deep hard-coal operations in the Ruhr—operates Sandvik DD2710 jumbos in heading profiles that require the B26F telescopic boom to re...

The rotary actuator on the Sandvik DD2710's boom positions the feed beam in its rotational axis—the angular orientation that determines whether the drill holes in a face round are correctly angled for the blast design. At Boliden's Garpenberg u...

Cuttings removal is the drilling variable that development jumbo operators in Swedish underground mines most frequently underestimate until it becomes a problem. In magnetite development headings at LKAB's Kiruna mine, the drill face generates a slur...

The feed beam is the component that most directly determines hole accuracy on a development jumbo—it's the structural rail along which the drifter advances during drilling, and its straightness over the full feed stroke length determines whethe...

The Sandvik DD2710 is a compact electric-hydraulic development jumbo designed for 3×3 to 5×5 meter cross-sections—the heading geometry that dominates Swedish underground iron ore and base-metal development programs. At LKAB's Malmbe...

A full-series seal assembly for the Atlas Copco RD22U is the definitive answer to a supply chain problem that affects every operation running this drifter globally: the decision, made under time pressure at a remote maintenance event, about which com...

Australian mining contractors operating multi-fleet drill programs across Western Australia's Pilbara iron ore country and the Eastern Goldfields gold operations face an equipment reality that European and North American markets rarely encounter at t...

The RD22U accumulator diaphragm operates under more demanding conditions than the RD18U equivalent—the heavier percussion class runs a higher pre-charge pressure, a larger pressure swing per percussion cycle, and a correspondingly higher mechan...

Thailand's fluorite and zinc mining in the Mae Sot border area and the potash projects in Udon Thani use the RD22U drifter in two contrasting configurations: jumbo-mounted for underground development, and excavator-mounted for surface exploration and...
