Conrad SBM 7.0C for Theo van Velzen grondboortechniek & bronbemaling

| Theo van Velzen grondboortechniek & bronbemaling bought a beautiful SBM 7.0C build on a Hitachi excavator from Conrad Stanen. Last week they picked up this special drilling installation with the low loader trailer.

The Conrad jetting mast SBM was originally developed for positioning 10-metre long filters at wellpoint drainage projects in one go. This jetting mast has become deployable for a broad range of options after more than 20 years of continued development. Therefore the description of this jetting mast being all round is plausible. The SBM of Theo van Velzen was equiped with a bottom clamp with a single cylinder to have the ability to drill closer to the retaining wall or building.

All-round as a standard

The jetting masts have already been delivered many times as different models with the following options in part due to the constant new requirements coming from our customer base:

  • Direct/fixed set up on an excavator where the boom is adjusted to create an optimal drilling set-up and transport situation. An excavator and jetting mast combination is a single unit.
  • Connection of the jetting mast to the excavator through a quick exchange system, which means that the excavator continues to be deployable multifunctionally.
  • Connection of the jetting mast to the auto load crane through a quick exchange system where both the auto load and the drilling functions can be operated through one and the same radio control unit.
  • Telescopic mast to realise a relatively large stroke of the drill head within specific transport dimensions.
  • Height adjustment between the mast and main hinge to ensure proper positioning over sheet pile walls or to be able to drill at deeper or higher situated surfaces.
  • Transverse rotation adjustment between the mast and main hinge for setting the mast vertically when the excavator is slightly at an angle.
  • Swivel/rotation set-up in the main hinge for optimally reaching holes that must be made very close to the wall or sheet pile walls without having to move the excavator.
  • Extendable main boom construction to ensure that holes can be made close up to the rig or, if required, further away from the rig.
  • The drilling process from the cab can be controlled through control handles that are fixed.
  • Both the drilling process and the excavator can be radio controlled remotely.
