Door Demon Hopper Trailer Opener - HTO

Arnold Company


Hopper Trailer Opener Promotional Video

Our customers made it clear that they needed the flexibility of a handheld unit with enough torque to get the job done, but not too much to avoid damage to the hopper trailer gate components. Rotation speed was also a critical factor, as the user needed to open the gate in an efficient, yet controllable manner. Weight was crucial as the unit had to be light enough for the user to operate it all day long. The new Patent Pending Door Demon Hopper Trailer Opener (HTO) combines all of those requirements into a feature-rich, powered unit with a custom shaft and interchangeable sockets designed for the task at hand.
