SLC System – Center Drive
Akkerman center drive slurry microtunnel systems (SLC) are designed to deliver maximum power directly to the rotating cutterhead and crushing chamber where it is needed. These systems use a proprietary water-cooled, variable frequency driven motor that is horsepower rated at the motor output coupled to a robust planetary gearbox for maximum torque while maintaining cutterhead speed.
FEATURES:
- All SLC series microtunnel systems are remotely controlled and operable from a single Akkerman Microtunnel Control Center (MCC).
- 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 to control hydrostatic balance to the cutting head or plenum chamber based on ground conditions.
- Sealing system rated to 3 bar; compatible with underwater retrieval.
- Mechanical and hydrostatic balancing with remote monitoring.
- Active MTBM monitoring and reporting including gas detection, roll, slurry monitoring, steering position, guidance, electrical connectivity, and more.
- All SLC systems compatible with Akkerman TGS guidance system; SL60C and larger also compatible with the Akkerman AZ100 guidance system.

Testimonials
In the trenchless world there are two things extremely important when selecting an equipment manufacturer to work with. Many companies will have one, but only the best have both. I’m specifically talking about experienced, knowledgeable employees and then equipment that can do what they say it will. At Akkerman you get both!
