Hyperboloidal spherical isolation bearing is a new isolation bearing researched and developed based on ordinary spherical bearing, which can meet the domestic requirement of high-performance isolation bridge bearing. This product has reached the international advanced level, filled the domestic gap and obtained national patents. It was tested and appraised by Henan Province in June 2004, and passed the technical review by Ministry of Railways in July 2007. Applicable bridges: It can be widely used for bridges and other construction which has the requirement of seismic mitigation and isolation. Product features: Novel and concise structure, clear damping principle, excellent seismic mitigation and isolation performance and excellent durability.

Hinged shaft sliding bearing is a new type of bridge bearing developed by adding high-performance plane sliding system based on common hinge shaft bearings and roller bearings, which meets the demand of railway steel truss bridge for high load, large displacement, large angle and low friction coefficient bearing. It passed the technical review by the Ministry of Railways in 2002. Applicable bridges: Railway steel truss bridges Product features: Uniform force transmission, long service life, high operational reliability, low building height and save steel.

Bridge swivel construction is a construction method that transforms the high-altitude operations across the barrier into swivel construction across the barrier after ashore or side operation. It is especially suitable for swivel construction across deep trench canyons, city overpasses, highways and railway overpass bridges. Swivel spherical hinge is the core component of swivel construction rotating mechanism and the key to ensure the safety and rotation accuracy of swivel construction. The swivel spherical hinge product developed by our Company adopts a new friction pair material, which realizes the high load bearing and low friction of the swivel rotating mechanism of the bridge and greatly reduces the rotating moment required for swivel. Product features: Large bearing capacity, simple structure, clear force transmission path, mature and reliable technology and high safety; Product serie: vertical bearing: 10,000KN - 300,000KN, special design and manufacturing for user requirements.

On the basis of deep research on the existing bridge expansion and contraction installation system, the bridge expansion and contraction installation with reliable quality, smooth running and good adaptability of expansion and contraction has been developed. Applicable bridges: It applies to various highways, railways and municipal bridges such as straight bridges, curved bridges, skew bridges and ramp bridges; Product features: Reasonable spacing between displacement boxes, uniform displacement control, high performance of profiled bar, good waterproof performance and durability; Product series: displacement 80mm - 1,200mm, special design for special displacement.

The Company specially provides the technical services and construction for special professional engineering such as disease treatment of bridge bearing and bridge expansion and contraction installation, bridge strengthening, traction and testing of overpass bridge swivel system.
