1.Descriptiion of Bridge Pot Bearing
Bridge pot bearings are the new generation of bridge bearings designed to meet
the demands of today's complex bridge structures. In modern highway engineerng,
the advent of longer span & continuous girder bridges, coupled with compound
curves and increased truckloads, have resulted in larger load and movements
concentrated on fewer piers, these loads and movement exceed traditional bridge
bearing capabilities. The Dynamic Bridge pot bearings are developed to meet
these complex design parameters.
pot rubber bridge bearing have been designed to be very easy to install, maintenance-free and cost-effective.Bridge Pot Bearings are designed for very high vertical, horizontal and lateral loads and where rotational structural displacements need to be accommodated.
The product has been successfully used in a broad range of applications which include: bridges, viaducts, high rise buildings, stadiums and dams.
4.Different types of Elastomeric bridge pot bearing:
(a) Twoway moveable bearing has vertical rotation,longitudinal and horizontal gliding
performances and its serial number is SX;
(b) One-way movable bearing
has vertical rotation and one-way gliding performances and its serial number is DX;
(c) Fixed bearing: only has vertical rotation performance and its serial number is GD.
