Long service life pot bridge bearing
Description of Pot Bridge Bearing:
Pot bridge bearing, with elastomeric pad embedded inside of the steel plate, is a special type of bridge bearings for taking large loads, large horizontal displacements and large rotation requirements in confined areas. Pot bearings are designed to carry combinations of vertical loads, horizontal loads, longitudinal and transversal movements, and rotations. This type of bearing can carry very high loads of over 50,000 kN.

- Depending on whether the pot bearing is fixed, guided sliding or free sliding. Pot bearings are categorized into three basic designs: Two-way bearing, One-way bearing and Fixed bearing. The principle of allowing slippage is that the structure contains teflon sheet(PTFE).
- By adding high damping rubber to the structure, we also can offer seismic isolation bearing from the foundation of One-way bearing and Fixed bearing.
Features of Pot Bridge Bearing:
- High vertical load, large displacement, simple structure and easy installation, mainly used to meet the need of large bridge construction.
- Low construction height, Light weight, compact structure and affordable cost.
- Provides longer service life compared to elastomeric bearing pad.
- Accommodate rotations at any axis and the appropriate movements of the bridge.
Applications of Pot Bridge Bearing:
- Incrementally launched bridges.
- Curved or skewed bridges.
- Structures with rotations in various directions.
- Structures using the incremental launching methods.
- Highways and railways, etc.
