The Patented* Door Demon Hopper Trailer Opener (HTO) is the latest innovation from the Arnold Company.
Everything about this unit has been designed from the ground up specifically for truck hopper trailers. 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 patented* Door Demon hopper trailer opener (HTO) combines all of those requirements into a feature-rich unit with a custom shaft and socket assembly designed for the task at hand.
