Hopper Gate Opener
Approximate Lead Time: 3 – 4 weeks
- 180 Degree Rotation
The Door Demon Dragon Fly pneumatic beam mounted hopper gate opener offers a permanent and powerful solution for opening your toughest hopper gates safely and productively. The unit mounts to a heavy duty “sled” which easily slides back and forth on a 6” beam (beam not included). The standard manual lift mechanism allows the user to choose from 9 different height positions and the shaft is telescoping with one universal joint. This combination provides maximum flexibility to meet almost any requirement.
The air motor operates best at 70 CFM @ 90 PSI using a ¾” line. The air motor drives a gear box providing heavy duty continuous torque to the power shaft which turns the railcar capstan. 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, but custom shaft lengths are available upon request.
