Increased Trailer Demand to Increased Success: CPS Trailer Company

CPS Trailer Company was founded in 1979 by Charleas P Siebert in a small welding shop in Oran Missouri. Charles used his initials for the company name, CPS. In 1980, CPS began building grain trailers – but they didn’t stop there. The demand for bottom dump trailers was the catalyst for their success.  

CPS experienced rapid growth as the demand for bottom dump and end dump trailers across the construction industry increased in the mid-late 1990s. CPS had a reputation for quality and spared no expense in making sure their welding and fabrication team was the best. CPS didn’t cut corners on the quality of their construction and took pride in manufacturing trailers that would last. In February 1998, CPS introduced their first half round demolition end dump trailer made from AR400 steel, believing it to be a great addition to their catalog.

Continuing the Tradition of Success

In 2002, CPS joined the Manac family. Becoming Manac’s first plant in the United States. Manac saw the value of CPS and understood the demand for bottom dump, end dump, and demolition trailers. The CPS facility remained in Oran, and continued producing dump trailers, only getting better under the Manac umbrella. With Manac’s reputation for excellence and extensive knowledge and experience, they were able to make tweaks to the designs of CPS trailers increasing their quality to meet Manac’s standards.

CPS trailers have always been great trailers. With Manac’s experience, now CPS trailers are excellent trailers, and have earned their place in your fleet.
