We have a modern fleet of 100% company owned Mack, Freightliner and Kenworth Trucks specifically designed and built to our specifications to provide the safest and most efficient way to handle pipe for our clients. Doing so, allows us to handle any project size in any location. All of our trucks and equipment are fully inspected and maintained to the highest standards on a regular basis.



The majority of the pipe we handle is hauled on our industry first self-steering pole trailers. Dun pioneered the fabrication and use of self-steering pole trailers as a way to haul pipe safely down the highway and in rural areas where the work space and condition of the roads is limited. Our trailers allow us to have maneuverability that you do not get with straight trailers.


Specialty Lifting Equipment

Providing another industry first, Dun began using the Vaculift and immediately saw the benefits of a safer more efficient way to handle pipe of any size and any coating. We have 46 company owned vacs that are constantly updated and maintained to provide the best service. Vacuworx Global, who produces 100% of our lifts, often relies on us to R & D new models and asks for our assistance in making the perfect machine.
