History of the Half round Dump Trailers
In 1991 a company called Ultra-lite developed concept of an aluminum ½ round trailer. their theory was revolutionary! But they had limited experience on using or building trailers until Jimmy Wink joined their efforts. Jimmy visited the plant and right away saw the need for improvements in the design. With these design improvements he ordered his first trailer to be used as a demonstrator for the mid west market. His changes to the designed followed the concept through several name changes and owner ship over the next 5 years.

For the past 29 years Jimmy Wink has owned and operated a fleet of over 50 dump trailers. Realizing the true capabilities of the 1/2 Round through experience first hand, he decided that the 1/2 round was undoubtably the best performing dump trailer on the market. Having close to three decades of first hand experience in this field, Jimmy felt as though he had the answers for all the design improvements needed to make the 1/2 round trailer the most sought after dump trailer on the market. And in 1996 Jimmy formed "American Trailer Mfg. " These trailers boasted an additional savings of 450 lbs.
In 1999 "American Trailer Mfg." was sold to "Fruehauf of Mexico" and relocated there. .

In 2009 Jimmy's non-compete was up and still full of innovations and Patent Pending ideas he formed
"Wink Trailer Corp."

Today , through extensive research and development, Jimmy Wink has developed the next generation of half round and square dump trailers. This new concept is unique because it combines two proven materials, aluminum and plastic. Which achieve the same results that current conventional designs achieve through the sole use of aluminum sheet and extrusions. These Patent Pending Utility Patents are just a few of the patents Wink has filed for protection worldwide.
