Heavy-Duty Vertical Lift Doors Designed
For The Mining and Steel Industries

24-ton mining haulage truck facility operates in all conditions.
"Each door is opened and closed between 20 to 40 times
a day - without a call for maintenance. They just aren't part of my work day unless one of
the trucks happens to come in contact with one of the doors. We have very few problems.
Our openings are very large and the doors operate in all kinds of weather. Other than some
fine tuning during start up, we've never had to maintain these doors."
