FIVE GENERATIONS OF BALDERSON ENGINEERING

Dymax five-generation heavy equipment manufacturing heritage

The Balderson family was building innovative, durable attachments before most of the major equipment manufacturers existed. Five generations in, the problems have changed, but the starting point is the same.

Our customers describe a problem. We figure out how to build the solution.

Today, that work continues at DymaxRail — innovative hi-rail systems, rail carts, and specialized rail machines. If your problem is outside of the box, bring it to us.
