With LOCTITE®, No Rock is Too Hard for Herrenknecht

Herrenknecht is the world's leading manufacturer of tunnel boring machines, with 100 machines at work on projects ranging from traffic tunnels in Kuala Lumpur to the Paris metro.

The machine’s massive cutting wheel and main drive are subjected to high loads, so Herrenknecht relies on LOCTITE threadlockers to ensure that highly stressed assemblies are reliably and permanently secured and to provide long-term vibration resistance. LOCTITE flange sealants are also used to increase reliability of the drive assembly.
