Abstract: This paper describes material reserch, fabrication, installation and rotating operation of 12000t rotating spherical hinge used in the construction of a large bridge across the Beipan River. Under a load of 10000t, the spherical hinge rotated smoothly with a friction coefficient lower than 0.018. In the application data to model testing of 10000t class spherical bridge bearings is supplemented and reliability of the bearing is testfied.
