The Rhino Cart Cart all terrain moving cart was created from the frustrations faced when using a traditional moving dolly. Door thresholds, small stones, cracks in the sidewalk, and uneven surfaces all stop a traditional dolly in its tracks. When you're moving an awkward and heavy item, abrupt stops can be dangerous. We set out to simplify the effort needed to move large and heavy items at home, in the shop, and on the job.
