Introducing a new line of product from Antraquip in our tunnel support division: 4 flange liner plates.
Liner plates are a cost effective and user friendly solution to support both small and large diameter tunnels and shafts. Thanks to their single plate stamped construction these plates are light enough to be manipulated by hand during installation but are strong enough to withstand the loads and pressures typically encountered while tunneling in soft ground.
Our liner plates are formed from a single steel blank and are never cut or welded during the manufacturing process. This seamless construction ensures rigidity and consistency, eliminating the possibility of a faulty weld compromising the strength of the panel.
Antraquip liner plates can also be used in conjunction with machine jacking, providing support for the freshly excavated tunnel as well as a solid face for the tunneling machine to push off of as it advances through the ground.
All liner plates and liner plate tooling are USA made at our facility in Hagerstown, MD. Manufacturing our own tooling allows us to quickly accommodate custom liner plate geometry on an as needed basis. Regardless of the width or radius desired, we can create the necessary tooling to produce your plates!
