Aker Wirth - Tunnel Boring Machines, Raise Boring and Full-Face Shaft Boring Machines

Aker Wirth offers wide range tunneling exploration drilling construction shafts ventilation production purpose.

Tunnel boring machines

Aker Wirth manufactures supplies tunnel boring machines mechanized tunnel driving geological conditions environmental requirements. Aker Wirth machines tunnel boring projects excavation wide variety tunnels.

Hard tunneling equipment

Aker Wirth tunnel boring machines (TBMs) classified into types: TBM (known Aker Wirth gripper TBM) boring stable rock shielded TBM tunneling varying formations alternate stable unstable formations. types TBM category machines enlargement tunnels Aker Wirth reamer TBM (TBE) inclined tunneling.

Mixed tunneling equipment

For tunneling mixed formations – soft – Aker Wirth provides shielded machines furnished functional features TBM soft TBM. Subject project requirements soft features pressure balance TBM hydro-/slurry shield TBM introduced.

Soft tunneling equipment

Tunneling soft unstable geological formations requires permanent support tunnel being bored. Aker Wirth provides pressure balance TBM hydro-/slurry shield TBM projects. Tunneling performed closed mode pressurization excavation face.

SBM VSI5X Impact Crusher, VSI Impact Crusher, PE Jaw Crusher, JCE Jaw Crusher

Aker Wirth equip hard-rock tunnel boring undercutting technology awarded Innovation Prize 2005.

Mobile tunnel miner

The tunnel miner specially developed tunneling. MTM excavate tunnel (rectangular horse-shoe circular).

The MTM working 'undercutting technique,' requiring cutting forces normal tunnel boring machine.

SBM VSI Impact Crusher, PE Jaw Crusher, JCE Jaw Crusher, Symons Cone Crusher

The equipped crawler gripper system. walking allows MTM without using crawlers. MTM equipped three eight cutting arms depending tunnel. muck transported rear similarly roadheader.

Raise boring

For decades raise boring accepted method installation production ventilation shafts passes mines. widely used technology infrastructural projects tunnel ventilation surge shaft hydro-electric projects.

SBM PE Jaw Crusher, JCE Jaw Crusher, Symons Cone Crusher, Hydraulic Cone Crusher

Aker Wirth raise boring machines cutters operation hardest rock 700MPa USC. ranges 112kW 600kW installed power cutting diameters 1m 6m boring depths 1,300m.

Aker Wirth built world’s largest raise borer HG 380 operating torque max. 710kNm. Aker Wirth raise boring machines largest diameter raise (7.1m) longest raise (1,260m).

Shaft boring solutions

For diameter shaft boring Aker Wirth offers solutions:

• Blind shaft boring (VSB)
• Shaft reaming (SB)

In latter case excavated muck falls pilot hole lower level. pilot hole 1m-2m diameter excavated raise boring machine.

SBM JCE Jaw Crusher, Symons Cone Crusher, Hydraulic Cone Crusher, Spring Cone Crusher

If pilot hole not possible blind shaft boring needs employed excavated material transported shaft surface.

Cutters tools

For products Aker Wirth supplies necessary spare parts cutter wear parts. Aker Wirth cutters strong wear resistant proven reliability field leading production rates costs per ton production.
