Product Introduction:
        TJGZ series speed lock bearing (LUB) is a kind of seismic bearing combined with speed locker (LUD), which has the function of sharing the horizontal force of the bridge while retaining the bearing function. At present, it has been widely used in domestic railways, highways and rail transit bridges. TJGZ series speed lock bearingIn the normal use of the bridge, the speed locker does not play a role, and plays the function of ordinary bearing; Under the action of braking force, wind load or seismic load, the speed locker automatically identifies and locks through the speed, and the original movable support is transformed into a fixed bearing, so that the movable pier becomes a fixed pier, and the horizontal load of the superstructure is effectively distributed to each pier, reducing the force of the original fixed pier and making the force of the bridge structure more uniform.
