BANN RIVER BRIDGE BEARING REPLACEMENT – COLERAINE TO LONDONDERRY RAIL TRACK

SDG tendered for the design and supply of the replacement bridge bearings, with Main Contractor and long standing partner, FP McCann. To date, this

has been one of our most technically demanding projects to work on, due to the shear level of bespoke design involved in the production of the bearings.

SDG worked closely with Manufacturer GUMBA based in Germany to design and supply a total of 36 Guided and Free Pot Bearings in accordance with EN 1337-5.

Pot Bearings are a proven bearing type, their industry standing has been achieved through the

combination of a non-reinforced elastomeric bearing (Natural Rubber) confined within a closed steel housing.

With a Pot Bearing, it is possible to transmit high vertical loads on a very small area, in the case of the bearings supplied to the River Bann Project, over 1600kN.
