SLP System – Periphery Drive
Akkerman periphery drive slurry microtunneling systems (SLP) are designed to deliver powerful performance for extended distances and curved alignments. These units include an on-board power pack with remotely selectable torque ranges to conquer changing ground conditions. Like all Akkerman microtunneling systems, the SLP lineup is fully remote-controlled from the surface and offers face access for cutterhead inspection, tool replacement, or obstruction removal.
FEATURES:
- All SLP series microtunneling systems use the same Akkerman Microtunnel Control Container (MCC) as SLC models, with an added remotely controlled periphery drive power booster container.
- Airlock kits available for pipe diameters of 78‑in ID and larger per PVHO and OSHA standards.
- Sizing kits available to accommodate multiple diameters with one MTBM.
- Interchangeable cutterhead types: Soft Ground, Mixed Face, Rock.
- Selectable high‑pressure jetting nozzles assist ground flow and cutting in cohesive soils.
- Variable‑flow slurry routing controls hydrostatic balance to the cutting head or plenum chamber based on ground conditions.
- Sealing system rated to 3 bar; underwater retrieval compatible with sealed adapters.
- Mechanical and hydrostatic balancing with remote monitoring.
- Active MTBM monitoring and report generation including gas detection, roll, slurry monitoring, steering position, guidance, electrical connectivity, and more.
- All SLP systems compatible with the Akkerman TGS guidance system.

Testimonials
Our interaction with Akkerman began on a project where we were struggling with their competition’s machine. Changing machines during a project to their machine required a leap of faith on our part. That project completed 20 years ago turned out to be successful and propelled us into 20 years of completing scores of successful micro tunnel projects throughout North America. Providing many innovations throughout this time has allowed us to mine many geology types and increase drive distances with curves to over 2500 lf. I can attest 30 years ago, technology did not exist that today allows us to complete projects efficiently and at a lower cost. Their leadership in providing technically superior AMERICAN made equipment is second to none in the world today.
