This EPD 3 section exterior mounted vertical lift door provides dependable operation under extreme wind and weather conditions, allowing life-saving emergency flights to occur.

EPD vertical lift doors solve problems associated with large openings.

This is the door of choice for very large openings when there are high wind loads and the sill area needs to be uninterrupted.
EPD vertical lift doors can also withstand most damages caused by vehicle or equipment collisions.
Vertical Lift Doors are manufactured with heavy structural steel and 14-gauge steel sheeting. (EPD uses steel manufactured in the USA whenever possible.)
Vertical Lift Doors can be a single panel or multiple panels.

EPD Vertical Lift Doors are durable for a reason...because we provide quality materials and superior craftsmanship.

Compare EPD doors to the competition:

EPD door panels incorporate a new revolutionary safety catch system in each door panel, not just the lower panel.
EPD uses heavy gauge sheeting on the door panels and applies 1-1/2" long high quality welds every nine inches on center around the perimeter and at the seams.
Competitors’ vertical lift doors have been documented to have just a tack weld every 18" on center. (This kind of tack welding doesn’t reinforce the panel and it allows a greater potential for the panels to buckle whenever they are loaded or impacted.)
The extra heavy duty operating system and structural steel materials used in EPD doors often makes them 35% to 40% heavier than the competitors’ vertical lift doors.

	Skillings Mining Review EPD Re-Discovering its Roots in Mining View article in PDF format
Reprinted with the permission from Skillings Mining Review: Electric Power Door (EPD), Hibbing, MN has rediscovered its roots by making a bigger impact in the mining industry over the past two years. But unlike the early 1960s when the company was mainly supplying the iron ore mines of northern Minnesota, recent sales have also been going to the western US, Canada, Argentina and Chile. There was a time in the late 1980s and early 1990s when sales were strong with military installations. And the company has carved a market niche for itself supplying security doors on jails and prisons. "It's all related," explains Cary Rhude, general manager. Click the links above to read more.

EPD's vertical lift doors are custom designed for each project to maximize the available opening dimensions.

The doors are equipped with high performance tight fitting weather seals and manufactured to withstand extreme environmental and abrasive dust conditions.

The doors can be designed for installation on the building's interior or exterior wall surface.
Interior mounted doors are more economical and normally used whenever there is sufficient head room inside the building.
Mounting the door on the wall's exterior surface allows for taller clear openings since the doors are stacked inside a weather-hood enclosure located above the header.
Exterior mounted doors are typically used on retro-fits or buildings with minimal interior ceiling heights.

EPD Vertical Lift Doors Save Money !

Maintenance costs are reduced because there are no springs used in the EPD vertical lift door. Torsion and coil springs are common trouble areas on rollup and overhead sectional doors. EPD’s cable and counter balanced operating mechanism typically out-performs a spring balanced system by 20 times.

EPD's reliable operating system includes:

Heavy duty weight counterbalancing
Door panel guide rollers with precision roller bearings
Guided counterweight box enclosed in a full height counterweight tower
A cable reeving system that balances loading and makes all panels travel at proportional speeds (not the bump and grind method used by some competitors)
Sheaves, cables, and shaft sizes that are larger, heavier, and designed to be longer lasting than parts used on alternate door types
A hand crank or hand chain for use during a power failure or emergency to quickly and safely operate the door. The manual operation speed is fast and reliable, since the hand crank does not rotate the motor shaft or gear reducer.
Options include vision lights, louvers, full size personnel doors, special cladding, and insulation.
