Ideal for open areas with challenging terrain where space is not a restriction, the Door Demon “Spider” three wheel hopper gate opener offers major stability in this unique design. Since you cannot tip the unit forward to engage the capstan, a hydraulic arm with cylinder will move the drive bit from 6” to 20” above the working surface allowing the user to easily adjust the height as needed. The wheels are 15” casters: either pneumatic or semi-pneumatic. You can the lock the front two wheels with a pin when side motion is not required.
The unit is available with electric over hydraulic, pneumatic, or DC battery power. The electric version utilizes explosion proof motors available in either 1 phase or 3 phase and all applicable voltages up to 575 volt. The pneumatic version operates best at 70 CFM @ 90 PSI using a ¾” line. The DC battery version operates with a 12 volt battery system and a built in charger.
Whichever power source you choose, the unit provides heavy duty continuous torque to the power shaft which turns the rail car 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.
