Wedge Locking solves vibration on Fans and general M&E Services in Tunnels

Tunnelling projects are very complex procedures and once created generally provide access from one place to another that is critical to the infrastructure where they are constructed.  These projects are designed to cause the least amount of disruption to the existing infrastructure and therefore space is limited and can be quite confined.

This means that any maintenance work required has to be done out of hours or if this is not possible it will cause disruption to the whole infrastructure.  The design of installed systems in tunnels is critical to ensure that maintenance is kept to a minimum.

This is where the WL series Wedge Locking Washer is perfect for bolted joints within tunnels because they provide an excellent solution to avoid issues with fasteners coming loose from the dynamic loads that are exposed to on these structures.  The need to go back and maintain bolted joints by re-tightening is absolutely not acceptable for tunnelling applications.  Once installed and tightened correctly the WL Series Wedge Locking washers will not come undone unless someone physically untightens them.

Typical applications in tunnels would be on the large extractor fans used to condition the air and remove fumes from vehicle carrying tunnels as well as general services to the tunnel such as electrical and mechanical equipment supports.
