From the minute you press the control button on your handy remote control, you'll be amazed at how this door functions. It's everything you want it to be and more.
The unit has all the bells and whistles and comes with single or 3-phase electrical components. Easy to read psi pressure gauge, service filter and fluid temp gauges let you know that the door is always working properly and at full capacity. Everything is in one compact hydraulic pump unit powered by 2, 3, 5 or 10 horsepower motors to safely lift even the smallest or heaviest doors and seal them tightly.
Schweiss Safety Advantage allows the door to lock up and down or safely lower or raise your door in case of electrical failure. Each unit comes with a standard tractor hydraulic hookup, lower the door at any time, very handy for agricultural or industrial applications. Specially designed built-in manual override allows the operator to lower the door in case of a power outage. Battery backup features use a DC battery or drill to operate the door in either direction in case of an emergency, giving you a superior backup system for your door and peace of mind.
They're powerful... We're talking THE most Efficient Pumps with standard motors designed ready to lift any size door, at any time, all the time!
Over the years Schweiss factory engineers rolled together customer comments, combined with high-tech design knowledge and experience to come out with perfection in a compact pump unit ready to be mounted anywhere you want it.

Schweiss Uses All-Steel Members
Internal Truss on this door External Truss is available
A 2x3-14 gauge steel member welded all around is good for about 120 PSF of wind. The steel is shop-welded, meaning no field labor is required. Every member of a Schweiss all-steel door is securely welded in place. Welds are strong and permanent and never need to be adjusted or tightened.
Spherical bearings reduce stress and wear on the cylinders, cylinders pins and clevises during operation "No one else in the industry offers this unique feature" only available on Schweiss Doors...
Hydraulic doors are large in size and just like an airplane wing, the doorframe flexes during operation. The hydraulic cylinders on each side of the doorway are connected to the doorframe and the building using spherical bearings. The spherical bearings accommodate the flexibility of the doorframe while at the same time allowing the cylinders to raise and lower the door without binding on the hydraulic cylinder pins and brackets. Spherical Bearings on both ends of the cylinder allow the cylinders to stay straight through the full range of motion.
"Soon as I saw understood the spherical bearings design it was a no brainer. I was immediately SOLD on the Schweiss Hydraulic Door!"

Schweiss doorframes are designed with double push tubes that are tied directly into the wrap-around hinges that connect both vertical push tubes directly to the header tube. The advantage of double push tubes is that forces of hydraulic cylinders are evenly distributed to the doorframe and the wrap-around hinges.
"There have been hydraulic doors with hinge welds that failed, literally tearing off the doorframe and destroying the door," Schweiss says. "Our design team provided a durable wrap-around hinge with grease zerks that are accessible without removing the top rubber seal."

The unique hinge design incorporates heavy hinge plates that wrap around each vertical push tube for added rigidity. Without this wrap-around design, the doorframe members can be overstressed and begin to tear apart from door weight and hydraulic forces over time. This won't happen with a Schweiss Door!
Hydraulic doors operate with one set of top hinges. These hinges need to be strong enough to support the door weight and the hydraulic cylinder forces when opening; unlike a bifold door that shares the load between the top hinges and the center hinges.
