Pile Top Rigs

RCD Rigs/Pile Top Drill Rigs

MHWirth is your first choice for reliable pile top systems for onshore and offshore applications. Cost efficiency and outstanding performance are the key factors that make us stand out from the competition.

Our pile top drill rigs (PBA) provide the most efficient solution for foundation drilling in mixed ground, boulders and hard rock. Six different machine models cover the diameter range from 0.6 to 8.0 m and can also be used to drill inclined, battered or raker piles. Our PBAs work on the reverse circulation drilling (RCD) method – a highly efficient drilling procedure. MHWirth is the world market leader in RCD.

We also provide a full range of hydraulic power packs (HPU). All HPUs present leading edge technology and are optionally available as multi purpose units allowing to also drive auxiliary equipment.

Our customers also benefit from our special tools for outstanding drilling projects, such as

  • Large diameter drilling bits up to 8.0 m
  • Rock bits with stinger
  • Drill bits with integrated underreamer pneumatic underreamer
  • Hydraulic underreamer with rotor and separate power pack
  • Milling tools to cut steel/deformed casings
  • Steel-pile cutting tools for decommissioning of oil and gas platforms
  • Cutters for all geological conditions up to 350 MPa (tool cutter, button cutter, button disc cutter)

Main Applications (Onshore and Offshore Foundation)

  • Superstructures and buildings
