Heavy engineering solutions focused on maintenance, inspection, and emergency repair of Tunnel Boring Machines (TBM) and complex industrial systems.
ForgeTech specializes in TBM maintenance, precise diagnostics, inspection, and emergency repair. In tunneling operations, every minute of downtime affects schedules, costs, and jobsite safety, so response must be immediate and dependable.
Hands-on field work with Robbins TBMs, multi-system troubleshooting, and equipment recovery under demanding underground conditions.
ForgeTech is purpose-built for the realities of live underground operations, where time lost is money spent and long OEM response windows are not acceptable.
Direct work on active TBM systems, not theory-only consulting.
Field-ready support to reduce the gap between failure and recovery.
Component-level repair and sourcing alternatives that avoid long manufacturer queues.
Mechanical, hydraulic, electrical, drive, and automation expertise under one roof.
Robbins EPB specialists. Precise diagnostics, preventive maintenance, and heavy corrective interventions.
Structural repair, rotating equipment, precision alignment, and full mechanical assembly.
High-pressure diagnostics, cylinder recovery, leak correction, and circuit restoration.
VFDs, main drive motors, and soft starters diagnosed and recovered when replacement cycles are too slow.
PLC troubleshooting, control systems, sensor loops, automation upgrades, and operator interfaces.
Fabrication and adaptation of custom parts on-site or in our workshop to ensure your project does not stop for lack of standard replacements.
The main drive system is the heart of any TBM. Failure of a frequency inverter, main drive motor, or soft starter can stop an entire tunnel project within hours. ForgeTech focuses on diagnosing and recovering these critical components, often without waiting for costly OEM replacement cycles.
Fault diagnosis, component-level repair, and full functional testing.
Inspection, winding evaluation, repair, and recommissioning.
Recovery and validation of critical motor-start control equipment.
Demonstration of applied competencies in real-world, high-complexity scenarios.
Flushing, stringent contamination removal, and high-performance filter replacement.
Management of EP2, Tail Grease, and excluder systems maintenance.
Cutterhead inspection, flange analysis, and precise torque verification.
VFD recovery, main motor inspection, and repair of associated cooling and control systems.
Logic fault diagnostics, I/O failures, sensor loops, operator panels, and drive control interfaces.
Rigorous pressure testing supporting extreme loads up to 305 bar.
Every hour a TBM sits idle compounds labor, equipment standing time, schedule penalties, and contractual exposure. ForgeTech closes the gap between failure and recovery through technical depth, on-site responsiveness, and practical repair options.
Faster diagnosis and repair cycles recover production hours.
Component-level repair reduces dependency on long lead-time parts.
Proactive support keeps critical equipment in production.
Whether it is an emergency on the job site or planning preventive maintenance for your TBM, our team is ready to act.
