Frequently Asked Questions
Frequently Asked Questions
Which product is best for me?
The best product is that which your facility has the power to run as many plants are limited to the source of their power. The second consideration is strain to the total system. A third consideration should be the environment in which the product will be used...both internal and external to the plant (i.e. humidity).
What about a moving capstan on the hopper gate?
We have several unit models that have optional side-shifting wheels (turning wheels) to move with the capstan.
How long does the DC battery last?
This duration of battery life is based largely on the size and condition of the doors. For difficult-to-open doors, the battery will typically open from 10 to 30 doors (up to ten cars). A complete recharge takes 4 hours at most, but the charger can be left connected for extended periods of time.
How high does the drive shaft move?
Our units operate in a range from 6 inches to 20 inches. Since we regularly create custom units, we can increase or decrease the range if required by your environment.
Which is more powerful: pneumatic or electric?
They are equally powerful since the motor and construction is the same. It is not a question of which is more powerful, but rather which power source is best for you.
How fast will your Door Demon
open a hopper gate door?
Most units will run at about 10-12 rpm. At this rate, the Door Demon
will open a hopper gate door in 15 to 30 seconds.
Can I change the rate of rpm of the output shaft?
Not really, no. The operating mechanism is open and close only...full power each way...but can be jogged lightly to open/close in small bursts.
How do I get replacement parts?
We use national brands such as Globe and Eaton.
for parts availability as we keep most parts in stock.
How long does it take for delivery of a Door Demon
If we have the complete unit in stock, you can expect delivery within 2 weeks. If we need to completely fabricate the unit based on your specifications and the options you require, please expect 3 to 4 weeks.
What is the price of a Door Demon
Between hopper gate door openers and freight car door openers we have nearly 15 different basic models available for purchase. Each unit's page on this web site has a "Instant Quote" feature that, when clicked (and you provide your email address) will provide you with a instantly quoted price (quoted unit configuration will be noted in the emailed quote) of that model. If you have any questions, though, please
