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.
The 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 that 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.
• Wall Mount • Floor Mount • Under the Bench • Back Room
- Under Workbench - Hydraulic power unit can be placed under a workbench or anywhere in the room.
- Wall Mount: Up or Down - mount anywhere away from the door opening or even in another room.
- Stand Alone Unit - Complete stand-alone hydraulic unit can be placed anywhere in the building.
- Up/Down/Stop Switch - Mounted near the door opening.
- Electrical Control Panel - Can be mounted independently from the hydraulic pump.
Schweiss hydraulic doors are custom made
to fit any size opening for your building.
Each door is built to fit your clear opening
without using up existing headroom.
There is no such thing as an odd size
door or a job too small. You dream it,
and we make your dreams come true.
Schweiss Doors is proud of its new
hydraulic doors that swing outward.
Already a leader in the bifold door industry,
Schweiss Doors also now offers a better
hydraulic door. The door design requires zero
headroom, comes pre-hung, is watertight, easy to
install, easy to operate with the push of a button, easy
to insulate and swings out to povide a canopy when the
door is in the open position.
Powered by a powerful hydraulic pump, two heavy duty cylinders activate the hydraulic doorframe. Hinges across the top of the doorframe allow it to swing out and away from the building to the full open position. The hydraulic pump can be located away from the door opening to keep a good luck.

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."
Schweiss engineered a new robust hinge design that distributes the door loads evenly across the self-supporting subframe, greatly reducing stress on the building structure.
The Schweiss robust hinges are designed to withstand the door weights and hydraulic forces of the cylinders as the door opens.
Your door is only as good as its hinges! Take one look at the Schweiss hinges and you will clearly see the workmanship, strength and functionality of each hinge. The Schweiss hinges are big... strong... heavy-duty.
The weight of the door and hydraulic forces exert loads on the hinge while the door is operating.
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.
Hinge surface area is critical on large moving doors. Over the years, we all have heard of hinge failures on others doors. Large hydraulic cylinders are putting extreme forces on each of the outer hinges of the doorframe. Schweiss has designed and patented a robust hinge with more surface area to evenly distribute the loads of a moving one-piece doorframe. Look at the hinge surface area. The stresses on the very outer hinges are immense. With that being said, take one look at the patented Schweiss hinges and you'll clearly see the workmanship, strength and functionality of each hinge.
It's very important to be able to grease the door hinges with a heavy viscosity grease. When grease is used on the hinges of a large moving door it avoids unnecessary wear and adds longer life to the hinge and the doors operation. It's a common manufacturing practice to use grease on the critical wear points and load points to avoid unnecessary wear just like in the industrial equipment world with implements such as payloaders, skidloaders and other industrial equipment that are being operated around the clock.
The new hinge design with grease points on every hinge segment enables owners - whether they be private individuals or commercial customers - to periodically grease their hinges from inside the doorframe without having to go through the cumbersome process of first removing the top rubber weather seal.
Doors move and flex as they open and close. The forces on each hinge vary during operation.
Spherical bearings reduce stress and wear on the cylinders, cylinders pins and clevishes during operation.
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 and understood the spherical bearings design, it was a no brainer. I was immediately SOLD on the Schweiss Hydraulic Door!”

Stopping the door completely in the event of a hydraulic component failure can be accomplished with a VELOCITY FUSE or a COUNTER BALANCE. The Schweiss Way
To have a door come down on a million dollar plane
or even worse than that, have the door come down
on people and put lives at risk!
“In the event of a hose or line breaking, it will not stop the door from falling.
It takes 7 seconds for a door to come down when a hose / line breaks.”
The door is coming down with no safety built-in to stop the door. Better clear the area!
If the manufacturer uses restrictors on the dead end of the cylinders, neither the restrictors nor the photo eyes will stop the door. You can't rely on the photo eyes to stop the door if a hose/line breaks on the dead end of the cylinder.
