Beam bridges are one of the most commonly used bridges for covering short distances, and are generally constructed on the local roads. Wood beams may be used for light loads. However, construction of multibeam bridge is more complex. Types of beam bridges include box girders, trusses and I-beams. Beam clamps should be used for carrying of heavy beams by bridge crane. A beam trolley may be also be used for carrying of light beams. Bridge load rating is determined to ensure the bridge safety.
