Powered Cutting Heads (PCH / PRH)
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.
FEATURES:
Powered Cutting Heads (PCH)
- PCHs feature independent hydraulic drive systems allowing the operator to control cutterhead and auger speed and direction independently.
- High‑pressure jetting nozzles assist with material transfer and cutting in cohesive ground.
- Pipe lubrication ports in the tail section promote a stable borehole and reduced pressures.
- Material is discharged and reversed inside the plenum chamber, creating mechanical earth balance during excavation.
- Increase kits are available to adapt to various jacking pipe diameters or types.
Powered Reaming Heads (PRH)
- PRH uses a single bi‑directional hydraulic drive system to turn the cutterhead and auger string simultaneously.
- Augers and casings connect via reaming arms for open transfer of excavated material.
- Material discharge is reversed inside the plenum chamber, sending cuttings to the reception shaft.
- High‑pressure jetting nozzles assist material transfer and cutting in cohesive ground.
- Pipe lubrication ports in the tail section promote a stable borehole and reduced pressures.
- PRH heads use a common drive and gearbox; shield bodies can be built for various jacking pipe diameters or types.

Testimonials
With its purchase of an Akkerman Model 5000 pump unit, skid base, and WM72C wheel machine in 2006, Northeast Remsco began its partnership with Akkerman that has resulted in its successful completion of many trenchless projects over the ensuing years using conventional wheeled machines as well as a variety of pilot tube equipment. I call it a partnership because the Akkerman team provides advice on the best choice of trenchless equipment for a project as well as how best to overcome jobsite obstacles when they arise, as they inevitably do. From their sales staff to their factory support team, Akkerman employees work with us to get the most we can from the equipment and to get the jobs done safely. They are a pleasure to work with!
