A DESIGN SHAPED
BY EXPERIENCE.
The 1/2 Round has been a central part of Jimmy Wink’s work in dump trailer design for decades.
Years of operating dump trailers firsthand helped shape an approach focused on how the body performs where it matters most — on the job.
That experience continues to influence Wink’s development of half-round designs today, combining practical knowledge with an ongoing focus on performance, efficiency and innovation.
