Committed to Excellence

The SIDUMP’R Difference!

In 2000 SIDUMP’R Trailer Co. produced its first commercial trailer in Plainview, NE and soon became a major competitor in the emerging side dump trailer industry.   The years since that first trailer, have bought continued integration between technology and demand to develop a quality trailer that is known to be the workhorse of the industry.

In 2010 SIDUMP’R was purchased by the Niewohner brothers.  These cattle feeders had been using a fleet of Sidump’r trailers in their operation and firmly believed in the quality and the value of the brand.  With a growing product line, came the relocation to its current facility in Columbus, NE.  The expansion to a 350,000 square foot factory has allowed for state-of-art manufacturing equipment to be installed and utilized.

Our men and women at SIDUMP’R Trailer Co. are committed to providing our customers with the best quality trailer and superior customer service.

What are the wet kit requirements to pull a SIDUMP'R Trailer?

Due to our single, 3-stage hydraulic cylinder, our wet kit requirements are unique and different from our competitors. So that you do not compromise your warranty, we ask that you please follow our specifications: Minimum of a 25 gallon tank, 42 gpm pump @ 1800 psi using 1” lines.  This will also enable you to achieve the optimum cycle time of 17 seconds.

There are four standard colors from which you can mix and match to meet your specifications: Black, White, Gray, and New Cat Yellow. Please feel free to speak with us about available custom colors.
