Track & Dolly System

Crawler tracks minimize downtime by navigating rough terrain and cramped spaces with ease while reducing the need to transport raw material to your grinder. We’ve maximized these time-saving benefits by adding a removable transport dolly that eliminates the need for a separate lowbed trailer.

Continuous Innovation

Reengineered to provide additional transport flexibility and increase the ease of use, our Generation II Dolly offers added efficiency and convenience to your transport needs. The Gen II Dolly incorporates an updated design to more evenly distribute the weight of the grinder, mitigating transport restrictions and obstacles.  Accessing and storing the dolly trailer hitch is now more convenient with the ability to slide the hitch directly inside the dolly frame, providing quick and easy access when transporting the dolly on its own. The Gen II Dolly option is available for the B-66L, B-66, and FP-66.

Maximize Your Uptime Productivity

If your grinding operation requires frequent moves between work sites and the enhanced maneuverability of tracks, the transport dolly requires less time getting ready to grind and more time producing engineered fiber commodities.

Tires to Tracks in Minutes

Our Track & Dolly system switches from road travel on tires to site navigation on tracks in minutes, eliminating the wasted time of unloading and loading your grinder onto a lowbed trailer. Tracks easily navigate rough terrain and cramped spaces, dramatically reducing the time required to position semi trailers in cramped spaces.

No Need for Special Tools

Powered by the main hydraulic system, our Track & Dolly system doesn’t require any special tools. Simply drive on and off the dolly with the crawler tracks and be ready for road or site transportation within minutes.
