Swivel Spherical Hinge
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 line: vertical bearing: 10,000KN - 300,000KN, special design and manufacturing for user requirements. Swivel Spherical Hinge Project performance: The swivel spherical hinge developed and produced for the Beipanjiang Bridge of Shuibai Railway has successfully realized the swivel of the 10,000-ton bridge structure for the first time and has been applied to Cable-stayed Bridge across Beijing Five Rings Shijingshan South Station, Shanghai-Hangzhou Passenger Line across Shanghai-Hangzhou Highway, 11 railway flyovers such as Wuhan Gusaoshu Beijing-Guangzhou railway flyover (swivel bearing 170,000KN), Shandong Zoucheng Swivel Bridge across Beijing-Shanghai Railway (swivel bearing 220,000KN), Shandong Heze Danyang Road Flyover Swivel Bridge across Beijing-Kowloon Railway (swivel bearing 250,000KN).
