For further details and technical specifications, see
the Unit Brochure
The "Dragon" pneumatic two wheel door opener is the perfect combination of mobility and speed designed to safely open the toughest railcar hopper gates. The powerful air motor and gearbox combination is designed to produce the most torque possible at an optimal speed for both productivity and safety.

The use of continuous torque provides significant power in a very controllable manner. Also, unlike pneumatic powered impact units often found in the market, the Dragon puts very little strain on the operator and operates at a much lower noise level with a rating of 90 decibels.

The unit requires 70 CFM @ 90 PSI, and you’ll need a ¾” line. The unit is equipped with an airline filtration and lubrication system and also comes with an extension shaft and drive bit. The standard shaft length is 26” long (shaft and bit), but custom shaft lengths are available upon request. The base model is equipped with non-turning wheels and manual height adjustment; however, hydraulically powered options are available as indicated below.

Available Options and Accessories:
  • Hydraulic powered lift kit for raising and lowering the power shaft
  • Hydraulic powered Side Shifting Wheels which makes traveling capstans and general mobility a snap
Other Technical Specifications
Maximum Noise: 90 dBA
Air Motor and a Non-Impacting Planetary Gear Reducer for Minimum Maintenance
Gear Reducer is Designed for a Lifetime of Operation
