Pot bearings will be installed between the bridge deck and the bridge piers. So, the deck can move and rotate.

Pot-type bridge bearings – fixed or sliding – can accommodate rotations of up to 0.040 radians in any direction and can be designed to accommodate any horizontal load or displacement. A pot bearing consists of a shallow/hollow steel cylinder, or pot, with an elastomeric disc, slightly shorter than the steel cylinder, fitted snugly inside. A steel disc, or piston, fits inside the steel cylinder and bears on the elastomeric disc. Flat brass sealing rings are used to contain the elastomer inside the pot. The elastomer behaves like a viscous fluid flowing within the pot as rotation occurs.

Special dimensional conditions can also be satisfied. Our pot bearings provide the high load capacity and large displacements that are required in large bridge structures. Xinyuan has provided thousands of bearings with vertical load capacity of up to 5000 tons, horizontal load capacity of 800 tons and movements of 800mm.
