The 23-2 rod (stay wire) anchor base provides the fixed connection foundation for the tension rods or stay wires of a tunnel anchoring compensation system, transferring rod tension reliably into the tunnel structure.
Manufactured to TB/T 2075.23-2024, Fittings for overhead contact system of electrification railway — Part 23: Tunnel anchoring compensation devices, the base is a plate-type welded fitting with an integral eye. The base plate carries anchoring holes for connection to tunnel embedments or expansion anchors, and the eye joins the rod or stay wire end through a pin so the load stays aligned.
Welds are continuous and full, giving the plate assembly integral load capacity, and the finished base is hot-dip galvanized for the damp tunnel environment. It pairs with the 23-3 tension rod assembly and 23-1 heavy-duty anchor arm in the complete anchoring set.
Henan Chuangwit Railway Equipment Co., Ltd. supplies the 23-2 under CRCC certification as part of the TB/T 2075.23 tunnel anchoring range, with mounting layout support on request.
