Rogers trailers haul bridge segments
When faced with the task of hauling more than one-thousand, 100-ton precast bridge segments on a steep downgrade to build twin bridges across the Susquehanna River, Edward Kraemer and Sons, Inc. looked to Rogers Brothers Corporation to build two trailers that could stand up to the challenge for one and a half years of continuous service. The trailers also needed to be economical and resaleable when the job was completed.
The size of each bridge piece, 57 feet long by 13 feet wide and 8.5 feet tall, was a major factor in the design of the trailer. Rogers engineers designed a five-axle, 100-ton capacity fixed gooseneck trailer with air lift suspension on the fifth axle and spring walking beam suspension on the first four axles.
The trailers’ deck size is 35 feet by 10 feet with pullout outriggers to handle the extra width of the bridge segments. Mainbeams and side beams fabricated with 100k psi materials, provide the strength and durability that are the hallmark of Rogers trailers.
