The vertical support of the roller shaft consists of an upper seat plate, a lower seat plate, rollers, a base, rubber plates, sliding plates, bushings, shafts, rocking seats, upper and lower pressing plates, and fixed plates. It has the functions of large displacement, large rotation angle, and vertical anti-lateral characteristics, making it suitable for bridge projects across large rivers, canyons, and seas.

The marine anti-corrosion spherical bearing is composed of an upper plate, a lower plate, a spherical crown lining plate, a spherical wear-resistant plate, a flat wear-resistant plate, shear blocks, shear pins, shear bolts, and an internal dustproof device. Its structure is consistent with that of ordinary spherical bearings, and the horizontal bearing capacity is 15% of the vertical bearing capacity.

The rotating support is composed of upper hinge, lower hinge, positioning framework, pin shaft, spherical wear-resistant plate, support system, etc. It is suitable for various types of cross-line bridges and cast-in-place beam construction on site for interchange bridges.

LYQZ spherical bearing is composed of upper seat plate, lower seat plate, self-aligning slider, concave liner, spherical crown liner, spherical wear-resistant plate, flat wear-resistant plate, pull-out bolts, upper and lower pressure plates, etc. It has the functions of large displacement, large angle, and vertical anti-lift characteristics, suitable for bridge projects across large rivers, canyons, and seas.

The wind-resistant bowl-type rubber support consists of an upper plate, a lower plate, a middle steel plate, a pressure-bearing rubber plate, a copper sealing ring, a rubber sealing ring, a polytetrafluoroethylene plate, a disc spring, a stainless steel plate, an adjustment plate, a retaining ring, and a transition plate. Its structure is consistent with that of a regular bowl-type rubber support, with the addition of a disc spring, adjustment plate, retaining ring, and transition plate, allowing for adjustable support height and excellent seismic and shock absorption performance.

The seismic isolation spherical bearing is composed of an upper plate, a lower plate, a spherical crown liner, a concave liner, a spherical wear-resistant plate, a flat wear-resistant plate, shear blocks, shear pins, shear bolts, and so on. Its structure is consistent with that of ordinary spherical bearings, and the horizontal bearing capacity is 20% of the vertical bearing capacity.

During the processing, each procedure strictly follows the quality management and monitoring procedures of initial inspection, self-inspection, mutual inspection, and dedicated inspection, while maintaining complete records of the product quality processing process, achieving controllability and traceability of product quality.

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.
