MAURER DB Expansion Joints (DB = Deutsche Bahn AG/German Railroad Company) for expansion ranges of 40, 80 and 130 millimeters are used in railroad bridges. A special pad profile ensures watertight absorption of motions, traffic load distribution as well as gap-free support of the crushed stone bed. Anchoring and watertight connection to the steel edge construction is provided by aluminum clamping strips and prestressed bolts. MAURER DB Expansion Joints are authorized by Deutsche Bahn AG. Larger expansion ranges can be achieved by series connection of MAURER DB Expansion Joints.
