The Demon Fly electric beam mounted hopper gate opener 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.

With safety in mind, the Demon Fly only utilizes explosion proof motors available in both single phase and three phase with multiple voltage options. The electric motor drives a hydraulic motor providing heavy duty continuous torque to the power shaft which turns the railcar capstan. The drive bit is a standard taper 1 ½” down to ¾”. The standard shaft length is 26”, but additional lengths are available per your request.

Motor Options and Accessories/Add-Ons:

  • 2HP Available In Single Phase or Three Phase and 3HP Available In Three Phase
  • 115, 208-230/460 or 575 volt available
  • Hydraulic Powered Lift Kit (shown bottom left) for Raising and Lowering the Power Shaft to accommodate varying capstan heights
