Precision Torque Control for Shield Tunneling Machine Maintenance

Lithium/Electric Torque Wrenches – Engineered for Reliability & Efficiency

Challenge:
Maintaining bolted connections in shield tunneling machines demands high torque accuracy, repeatability, and durability to withstand harsh underground environments. Manual torque tools risk under/over-tightening, leading to component failure or downtime.

Solution:
Our lithium-powered/electric torque wrenches deliver:

1. High Torque Accuracy (±1–3%)

   • Ensures precise tightening of critical bolts (e.g., cutterhead segments, thrust cylinders, segment rings).

   • Prevents flange leaks or structural loosening under dynamic loads.

2. Ergonomic & Efficient Operation

   • Cordless design with long-lasting lithium batteries for confined tunneling spaces.

   • Programmable settings (torque/angle) for ISO/DIN-compliant joint integrity.

3. Ruggedized for Tunnel Conditions

   • IP54+ rated against dust/moisture; shock-resistant construction.

   • Data logging (Bluetooth/USB) for audit trails and predictive maintenance.

4. Versatile Applications:

   • Cutterhead bolt tensioning

   • Segment ring assembly

   • Thrust system maintenance

Why Choose Our Tools?
✔ Reduced rework & downtime in TBM maintenance cycles.
✔ Compliant with EN 1090-2 and other heavy equipment standards.
