Equipment

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 can be operated by one common 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 to assist ground flow and cutting in cohesive soils.
• Variable flow slurry routing to control hydrostatic balance to cutting head or plenum chamber based on encountered ground conditions.
• Sealing system to 3 bar capacity.  Underwater retrieval compatible.
• 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 SLC systems compatible with Akkerman TGS guidance system.  SL60C and larger also compatible with Akkerman AZ100 guidance system.
