CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The thrust system generates the forward force needed to push the TBM cutterhead into the tunnel face. It uses hydraulic cylinders that extend against the tunnel lining to create a reaction force, propelling the machine forward while maintaining stability.
Typical rated thrust force ranges from 3000 to 10000 kN, depending on the TBM size and ground conditions. The exact value must be confirmed with the manufacturer for the specific model.
The thrust force is distributed evenly among multiple hydraulic cylinders (typically 8 to 16) arranged around the shield. This even distribution prevents machine rotation and misalignment during advancement.
Relevant standards include IEC 60529 for ingress protection, and ISO 3448 for hydraulic fluid viscosity. These are reference standards; compliance must be verified with the manufacturer.
