The TSSF series expansion devices are mainly designed for medium and small span passenger dedicated railway bridges. Since the expansion devices set at the ends of medium and small span railway bridges do not directly bear the load of the wheels, the expansion devices in this usage environment primarily focus on adapting to the expansion of the bridge and waterproof performance.

Scope of application: The comb-tooth type expansion device is suitable for installation on thin-walled beams or bridges with shallow embedded grooves, for various types of bridges with a displacement of ≤400mm.

Scope of application: Noise-reducing telescopic devices are suitable for installation on urban bridges or in places with noise restrictions.

Scope of application: Multi-joint expansion devices are suitable for installation on various types of bridges with a displacement of ≥160mm. When selecting, choose the appropriate Model based on the bridge's maximum design displacement and the depth of the embedded groove.

Scope of application: Single group expansion devices are suitable for installation on various types of bridges with a displacement of ≤120mm. When selecting, choose the appropriate model of the expansion joint based on the actual embedded groove depth.
