HYDRAULIC DOORS by SCHWEISS
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.
HYDRAULIC DOORS
Schweiss Doors is proud of its new hydraulic doors that swing outward. Already a leader in the bifold door industry, Schweiss Doors 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 provide a canopy when the door is in the open position.
SIMPLE UNIQUE DESIGN
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 clean look.

CORDLESS DRILL BACKUP - OPTIONAL
THERE'S A BACKUP WITHIN A BACKUP
GUESS WHAT - There's another backup on standby!
Grab a cordless drill and run the door up!
Scenario - 1
Let's say you go to raise your door in an emergency with the
battery backup only to find out the battery is dead . . . Now what?
Scenario - 2
Highly unlikely, but for some reason the hydraulic gear
pump motor took a puke.
Auxiliary Backup Pump
The auxiliary pump in the tank will raise and lower the door with a handheld drill. If you arrive at your door and the battery is dead, now you have the option to use a cordless drill to open or close the door!
HOW DOES THIS WORK?
The DC motor has its own stand-alone auxiliary hydraulic pump. On the top of the DC motor is a hex-head nut - use a cordless drill to open your door!
HAS ITS OWN HYDRAULIC PUMP
When you order the Battery Backup System,
it comes with its own gear-driven auxiliary pump.
SCHWEISS ADVANTAGE HAS YOU COVERED
The Backup Systems ensure that
you can get your door open or closed under most conditions.
Cordless Drill Operation
Easy operation with any handheld drill.

HINGE DESIGN...
NEW
"OUR NEW WRAP-AROUND HINGE DESIGN SETS THE NEW STANDARD FOR HYDRAULIC DOORS"
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."

EVERY DOOR HAS ITS OWN SELF-SUPPORTING SUBFRAME
Schweiss hinges distribute the door loads evenly across the
self-supporting subframe greatly reducing stress on the building structure
THE HINGES SELL THE SCHWEISS DOOR
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.
GREASE ZERKS
- • Schweiss hinges can be easily greased for longer hinge life.
- • SCHWEISS is the only manufacturer to offer hinges that can
be greased from underneath the door without removing the
top weather seal.
REMOVABLE HINGE PINS
- • Removable hinge pins are a better design.
- • They are never welded in solid on a Schweiss door.
- • Designed for easy maintenance.
- • All hinge pins are removable.
The hinge makes the door...
The weight of the door and hydraulic forces exert loads on the hinge while the door is operating.
so it had better be STRONG!
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.
WHAT DOOR CUSTOMERS ARE SAYING...
• "The hinges sold me."
• "The Schweiss team hit a home run by putting grease zerks in their hinges."
• "Now that's a Serious Hinge, You guys have it figured out!"
• "Oh My, nothing comes close to it. Professionally done!"
• "Nothing on the market will even come close to the Schweiss hinge design."

Customers Welcome Greasable Hinges
HINGE SURFACE AREA
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.
GREASABLE HINGES
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.
Advantages of Grease
Using grease on the hinges is a better method of lubrication.
Using grease on the hinges is the industry standard.
Using grease on the hinges makes for a quiet door.
Using grease on the hinges makes for a smoother operating door.
Using grease on the hinges extends hinge life
Greasable hinges last forever.
Look at the Schweiss hinge, it has more lubricated surface area to give you longer life
Others rely on bushing FOR LUBRICATION
Doors move and flex as they open and close. The forces on each hinge vary during operation.
Not all bushings wear evenly.
Bushing wear thin over time.
Worn bushings offer less lubrication.
Less hinge surface area to distribute the door loads across the door header tube.
No way to inspect the bushings when the hinge pins are welded in - not removeable for inspection.
Almost impossible to replace the bushings when the hinges pins are welded in solid.
Greasable hinges LAST FOREVER!

LARGER CYLINDERS WITH
SPHERICAL BEARINGS
"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.

STEEL HORIZONTAL CROSS MEMBERS
SCHWEISS MANUFACTURES ALL-STEEL HYDRAULIC DOOR FRAMES
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.
WOOD HORIZONTAL CROSS MEMBERS
As you open the door, it flexes due to the variable wind load and its own weight. Tec screws or bolts in the end of a 2x4 are good for about 40 PSF of wind if the screws or bolts don't split the wood. Tec screws or bolts used to fasten horizontal wood cross members to the doorframe may work loose over time. Wood may shrink over time. The screws or bolts may shift in the the horizontal wooden cross member, eventually working their way loose.
