High torque is useless if the TBM machine overheats because excess heat causes failures, reduces efficiency, and negates performance gains in tunneling.
Torque logs can support claims on a TBM tunnel job by providing accurate data on machine performance and ground conditions, strengthening project documentation.
High torque lets a TBM tunnel run lower rpm safely by reducing cutterhead wear, minimizing jamming risk, and improving control in tough ground conditions.
