The 23-3 tension rod assembly connects the anchor base to the compensation device in a tunnel anchoring system, transmitting the full anchoring tension while allowing the assembly length to be fine-tuned during installation.
Manufactured to TB/T 2075.23-2024, Fittings for overhead contact system of electrification railway — Part 23: Tunnel anchoring compensation devices, the assembly consists of a forged rod body, end fittings and a central adjuster. One end carries an eye connection, the other a clevis (tongue) connection, matching the 23-2 anchor base and the compensation device interfaces; the central adjuster sets the exact length so the system installs to design geometry.
The rod body is forged and hot-dip galvanized for the tunnel environment, and the adjusting mechanism operates smoothly and locks securely once set.
Henan Chuangwit Railway Equipment Co., Ltd. supplies the 23-3 under CRCC certification together with bases, anchor arms and pulleys as the complete tunnel anchoring package.

What end fittings are provided?
An eye connection on one end and a clevis (tongue) connection on the other, matching the base and compensation device interfaces.
Is the rod suitable for the full anchor tension?
