1. Description :

DW Bridge Bearing is installed between the upper and lower structures of the lower part of the bridge, supports the upper part of the bridge, absorbs the dead load and live load of the bridge and transfers it to the lower part of the bridge, and it is A device that absorbs and cushions the expansion and contraction of bridges due to changes in temperature, dry shrinkage, concrete creep, dead load, and live load wind load, etc.
