The Worksman Heavy Haul Trailer is a great compliment for the Worksman Mover and Adaptable Tricycles. these sturdy units hitch onto the back of the tricyles (Shown attached to our Adaptable Tricycle in image shown), allowing you to have additional cargo space.

When a maintenance worker needs to have this equipment, they simply take this trailer with them as needed. Other companies attach dedicated tool boxes. The potential uses are quite varied.

The platform measures 22.5"x23" and wheels are 20"x2.125".
