Equipment

Akkerman Inc.

Akkerman’s Powered Cutting Heads (PCH) and Powered Reaming Heads (PRH) set the standard for pilot tube microtunneling. These powerful units increase the diameter of the bore to match the final product pipe while reversing the direction of the material discharge of the excavated material to the reception shaft in order to install any standard allowable jacking pipe suitable for the application.

Powered Cutting Heads (PCH) Features:
  • PCHs feature independent hydraulic drive systems that allow the GBM operator to independently control the speed and direction of both the cutterhead and augers.
  • High-Pressure Jetting nozzles are controlled by the operator to assist material transfer and cutting in cohesive ground conditions.
  • Pipe lubrication ports are plumbed into tail section to promote a stable borehole and reduced pressures.
  • Material discharged and reversed inside the plenum chamber creating a mechanical earth balance during excavation.
  • Increase kits are available to adapt to various jacking pipe diameters or types.
Powered Reaming Heads (PRH) Features:
  • PRH uses a powerful single hydraulic drive system to turn the cutterhead and auger string simultaneously. The drive system is bi-directional.
  • The augers and casings are connected to the PRH by reaming arms which promote an open transfer of excavated material to the augers.
  • Material discharge is reversed inside the plenum chamber sending excavated material to the reception shaft for removal.
  • High-Pressure Jetting nozzles are controlled by the operator to assist material transfer and cutting in cohesive ground conditions.
  • Pipe lubrication ports are plumbed into tail section to promote a stable borehole and reduced pressures.
  • PRH heads utilize a common drive and gearbox setup. The shield body can be built to match various jacking pipe diameters or types.

Testimonials

Super Excavators, Inc. has enjoyed a long partnership with Akkerman over the years. We originally bought a competitor’s microtunnel system and had nothing but problems with quality and service. Finally we called Akkerman and bought their SL36 microtunnel system. Since then we have never looked back. We have bought several other pieces of equipment from Akkerman. From GBM equipment to ABIS to several microtunnel cutting heads. They have been great working with our staff to customize the equipment for our specific needs. We have put their equipment to the test on several projects by pushing the envelope in long drive distances and very difficult ground conditions. The equipment has responded well and together we have made modifications to continue to improve on efficiency. In our business it is necessary to have people their when you need them. Akkerman has done a great job at supplying quality equipment and servicing our needs in a timely matter, helping keep our work on schedule.
