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
Capitol Tunneling was awarded a Sub-Contract from E.S. Wagner on ODOT Project 277 (18) in Toledo Ohio in 2018 and patterning with Team Akkerman was vital to the project’s success. The installation consisted of 2600 feet of 66″ casing utilizing the Akkerman 540 series 2 TBM, the 5200 Pipe Jacking unit, and a wide range of support equipment. Not only did the equipment outperform our expectations, the technical support went above and beyond from the start. From onsite training at Akkerman’s facilities in Minnesota, to the project site training by expert field technicians, they provided support and expertise from set up to completion. Thank You Team Akkerman for making our project a success and for thoroughly educating our team members while providing world class equipment. Your commitment to excellence allowed us to complete the project the way Capitol Tunneling Inc. expects all project to be completed…On Line…On Grade…and On time
