Do you need a sturdy, quick opening One-Piece® door? A hydraulic door is ideal in situations where maximum clear opening must be maintained. The hydraulic door swings up and away from the building so there is no loss of headroom outside or inside the building. With the push of a button, your door will quietly, quickly, and safely open, giving you access to the full available space your building has to offer. A builder can easily work this new Schweiss One-Piece® Hydraulic door into a structure where headroom is an issue.
Schweiss hydraulic doors offer options such as:
A special feature of the custom-built One-Piece® hydraulic door is that it comes pre-assembled, pre-welded and delivered pre-hung within its frame for easy installation. The buyer/builder gains tremendous flexibility, saving time and money.
Schweiss hydraulic doors are pre-built with a special bottom external truss that provides added strength and rigidity... very important in high-wind conditions.
Provides an extended canopy in the open position. Door swings outwards when opening, requiring space for the door to travel.
The One-Piece® hydraulic doorframe is opened with two heavy-duty hydraulic cylinders, one on each side of the door. Cylinders come with spherical bearings. The entire weight of the doorframe is transferred back to cylinder legs that pre-mount to the building column. A fully opened hydraulic door extends straight out from the building (Looks like a large airplane wing) exerting forces back to your building structure. The entire building structure must be designed to carry these loads.
The doors are extremely weathertight. The hydraulic cylinders pull the door secure against the building!
Schweiss power units are a powerful, secure and simple solution to raising and lowering the doors. Each door consists of only three major components: the door (pre-hung with frame), two hydraulic rams and hydraulic pump.
All hydraulic door power units come standard with tractor fittings, which allows your door to be opened in case of a power loss!
Hydraulic doors are designed with one set of
heavy-duty hinges that carry the entire weight of
of the hinge but it spreads the
forces over a broader portion of the door.
The Schweiss hinge design is robust. It's all about surface area. The more surface area you have in the hinge design, the lower the stresses will be on all the components. The Schweiss hinge design has 22" of surface area that will give you years of service no matter what size door.
Schweiss is the only manufacture that has grease zerks that allows the owner of the door to grease the hinges for longer life.
The bifold doors have been around for many years and the unique design has made Schweiss Bifold Doors the leader in the market. Schweiss Doors has design features built into each door that make the them stand out in a class of their own. Below we list some of the designs that make the Schweiss Bifold a good choice.
Our patented heavy-duty lift straps raise and lower the bifold doorframes using multiple lift-straps evenly spaced across the entire doorframe to
provide an even lifting force. The nylon lift straps rated at 29,000 lbs. tensile strength attach to the bottom of the doorframe at multiple locations to keep the door even when lifting while never binding or making noise like an outdated cable-lift door.
|Lift-straps raise and lower the door.
|Lift-strap doors DO NOT require pulleys or cables, have fewer parts, fewer problems and less maintenance.
|Lift-straps wrap in a spool to raise and lower the door, increasing operating speed.
|Lift-straps operate very quietly.
|Lift-strap are safer than outdated cables.
The doors are extremely weathertight. The new strap-latch pulls the door secure against the building!
Bifold doors have two sections; a top half and a bottom half that provide advantages.
The fact that bifold doors fold in half instead of just swinging out, allows for more open ramp/vehicle space in front of the hangar. It also allows the full use of the width of the hangar, making the entire end wall a door.
Bifold doors form a canopy when open, that provide shade. Another important feature is it allows moisture to run off the open door.
The taller the door wedge, the less stress it exerts onto the building structure. The wedge itself is the strength in the design.
Bifold doors are manufactured with an internal truss that's mounted on the inside of the doorframe for added strength and proper wind loading on the door.
The Aircraft Hangar Building is only as good as it's "Door." The door you choose is a huge decision. Let Schweiss help you make this choice. Explore the different hangar door designs. Schweiss is willing to share with you the detailed door comparison of each design so you can make the correct decision and select the door that works for you.
If you're thinking about buying a door for your aircraft hangar we are about to educate you on many important features and decisions you have control of! There are no insider secrets with Schweiss Hydraulic Doors we put all our cards on the table.
Did you know that a custom built door for your aircraft hangar does not cost as much as the hangar itself? The word custom can be deceiving. The major hangar manufacturers quote the price of the door included in the overall building quote. Have your building company separate the door package prices from the building quote. Schweiss wants you to have an affordable new hangar building with a beautiful automatic hydraulic or bifold door of your choice. You do not want to find out later that you could of bought the exact same hangar from the same manufacturer less the door and saved thousands. When someone is overcharging you thousands of $$$ on a door alone, do your homework before shopping!
Some building designs may be underbuilt and end up costing the end-user of the door more money. Schweiss provides the building manufacturer and door owner with a full set of detailed Spec Sheets that provide the weights and moments that your door applies to the building. It's important to build the building endwall / sidewall to accept the door of your choice. Before fabrication of the hangar building, Schweiss can provide the building manufacturer with the Spec Sheets. Take no short cuts! Do it Right the first time!
Knowing about different door and building designs can save you thousands of dollars. For example, did you know that you can put a high quality hydraulic door on your aircraft hangar and save thousands on your building cost alone! Schweiss is also going to show you detailed pictures and technical drawings of doors so you will better understand the hangar door yourself and save thousands when buying your prefabricated building.
We're about to discuss the two different airplane hangar door designs. Schweiss manufactures the best two superior door designs available. Each have advantages and differences and some are better suited for specific climates and applications than others. Let us explain the many advantages and facts. This will give you a helpful overall guide to selecting the door of your choice to accommodate your building with the intention of getting the most for your dollar with the best door design money can buy.
Most airplane hangar building manufacturers will only tell you about the door they happen to sell. And guess what... you may end up buying a door that doesn't fit your needs!
Most people only know about one or two designs or they talk to a salesman who tries to sell them a specific door regardless of whether it's the best suited for their specific situation. Each door is different and each has its place. Each door has a different price.
Don't get caught up buying too low of a sidewall building height. Yes, it's great to save money, but it's also important to have some wiggle room when it comes to clear opening height. If you max the building out and need more headroom at a later date, you'll find it hard trying to elevate the building because your rafters are not high enough from the start. Think about headroom and plan for the future.
The hydraulic door is one of the most recent door designs available. This "one piece" door pivots at the top, requires only one set of hinges horizontally and swings open forming a large canopy in the front of your building. It is actuated by two powerful hydraulic cylinders with one hydraulic ram on each side of the door. The Schweiss hydraulic door is one of the best automatic door designs available today. Schweiss has always offered people choice's and our superior hydraulic door does just that!
Listed below are many advantages and facts we'll share with you
Provides additional strength to your buildings
Makes installation easy - Lift the Framework and Door into place all in one step
Framework is Standard on all Schweiss Hydraulic Doors.
Zero Headroom Required - Lower your building cost by lowering your building height. That alone will save you thousands of dollars.
Lets you open/stop/close your hydraulic door from any vehicle. Customers really enjoy this feature!
Warning: All doors equipped with remote operators should have a warning system to alert persons in the immediate area that the door is moving.
Hydraulic doors that are "One Piece" and swing out when opening require more open ramp space in front of the airplane hangar for the door to open. You can't park a vehicle or aircraft close to the door. Schweiss recommends you install a window within the hydraulic door so the door operator can view the doorway before operating the door.
P.S. If you park your plane or equipment too close to your hydraulic door opening you may hear some expensive noises when opening the door.
It's important to have a truss at the bottom of the hydraulic door to keep the door from sagging when it's opened. This same truss when located on the front side of the aircraft hangar door can collect debris and snow. Snow and debris must be kept clear from the front sides of the hangar for the doors to be able to open. Multiple truss options are available through Schweiss hydraulic doors to give you the clean look. Schweiss custom-builds each door!
Door when opening, cantilevers outward, lying perfectly flat in the open position. Do not keep the hydraulic door open during heavy winds, snowing or raining conditions.
Schweiss hydraulic doors have built in safety features like velocity fuses in the hydraulic cylinders to prevent the door from closing in the event of a hose or line breaking. Flow control and soft shift valves located on the hydraulic pump allow Schweiss hydraulic doors to open and close smoothly preventing any jerky motion when operating your hydraulic doors. Schweiss doors are built with safety in mind!
Schweiss is a leader in the hydraulic door manufacturing. With the Schweiss Hydraulic door company there are no secrets...everything is explained upfront.
Schweiss doors offer many features to make using your door easy to operate. Remote controls are a great addition to your door. With the press of a button, you can open or close your hydraulic door without ever leaving your vehicle. Entrance lights are another great add-on that can be positioned anywhere more light is needed when opening your hydraulic door.

What a customer once shared with us... "A door is a door... Right? WRONG! Like many people, I thought all hydraulic doors were pretty much the same, but boy did I learn my lesson. A hydraulic door is only as good as its components, and workmanship, that's what sold me on the new Schweiss Hydraulic Doors. After helping a neighbor install and operate his "One Piece" Schweiss hydraulic door, that sold me right there and from then on I knew Schweiss Doors was the right choice for me!

Allows for Flexing
Allows for Flexing
Spherical bearings reduce stress and wear on the cylinders, cylinder pins and clevises 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.
( not about a Schweiss door )
Solid metal - pure strength!
The entire weight of the door relies on the Top Cylinder Plate to provide adequate strength to support the weight of your door in all positions.
Assortment of different size metal pieces that need to be welded together!
Tec screws or bolts used to fasten wood to the doorframe may work loose over time. Wood may shrink over time. As you open the door, it flexes due to the variable wind load and its own weight. The screws or bolts may shift in the wood, eventually working their way loose out of the wooden crossmember.
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.
1 Step - A simple touch of the button lets you open/close/stop your door at any height. When door stops/ motor shuts off automatically. The motor automatically stops when you take your finger off the control station.
with welded connections
- Door's subframe
4x6 header tube adds building/door support
- 4" x 5" side column adds extra support
- Horizontal members 4" deep - all welded connections
- Vertical members 4" deep
And allow more room for better R-Value insulation
Steel is a uniform material
All steel is a consistent grade and strength
Welds are strong and permanent
Welds never work loose
Schweiss uses 4" wide steel members
A 10-foot-long utility grade 2x4 is only capable of resisting a 23 mph wind. A 10-foot-long 2 x 3-14 gauge steel member is capable of resisting a 120 mph wind. Ask yourself how often the wind is greater than 23 mph? What do you think that would do to your utility grade 2x4.
A 2x3-14 gauge steel member all around is good for about 120 PSF of wind. The steel is shop-welded, meaning no field labor is required. Welds are strong and permanent and never need to be adjusted. Every member of an all-steel door is positively welded in place.
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. As you open the door, it flexes due to the variable wind load and its own weight. 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 horizontal wooden cross member, eventually working their way loose.
Quality wood is clearly identified. It is grade stamped "SELECT." It doesn't have large knots and splits. Even if the wood was "SELECT," it would only resist a wind of 12.3 PSF. All wood is not created equal. Steel is a uniform material. Steel is all a consistent grade and strength. When you get an all-steel door - including steel horizontal crossmembers- you know that the material quality is consistent.
The vertical bifold door hinges horizontally in the middle and is operated with an electric motor which spools the straps to lift the door. Vertical bifold is the most popular design for hangar doors. Surprisingly the vertical bifold door has been the people's door choice for many years and continues to be.
Listed below are many advantages and facts that we'll share with you.
Older style bifold doors only came standard with . . .
IT'S A FOLDING WALL - Clean, Neat Looking Door
Maintenance Free - Operation is relatively maintenance free
Less Moving Parts - with the new "Lift Straps," gone are pulleys and cables to service
Premounted electric motorized driveline attached to the bottom door panel.
When in the open position bifold doors protrude out half the distance, exerting less forces to your building structure and also less potential for wind or snow damage when open.
When a bifold door opens, the doorframe folds into a V ( sideways ) or a wedge acting as a huge truss supporting each of the 2 piece bifold door sections. The larger the door wedge the less stress it exerts onto the building structure.
Because these doors are so large, the fact that they fold in half instead of just swinging out takes much of the stress off the front of the building.
Lift Straps are rated for 29,000 pounds and are used to raise the two-section folding doorframe. Bifold doors have multiple lift points throughout the width of the doorframe to evenly distribute the loads of the door across the building door header putting less stress on the hinges & doorframe.
Double sets of heavy-duty hinges support the folding doorframes, two sets are better than one.
Auto Locks Included - Powered by the drive motor to lock and secure the door
Automatic operation makes opening and closing easy and painless.
Pulls the door tight to your building ... weathertight
Simple Clean Design
Great Improvement ... No More Cables and Clamps
The fact that they fold in half instead of just swinging out, Bifold doors allow more open ramp/vehicle space in front of the hangar for the door to open. Allows the full use of the width of the hangar, make the entire end wall all-door.
Bifold doors form a canopy when open that provide shade. Another important feature is it allows moisture to run off the open door canopy.
Zero Headroom Required - Lower your building cost, this alone will save you thousands.
Bifold doors fold in half and are slightly angled to allow rain or snow to drain off the front of the door and not collect on top of it.
Bifold doors lift up when opening ( do not swing out ) -- Ice and snow is never a problem
Bifold doors do not require floor tracks that can fill up with debris or ice.
Best sealing door on the market - top / center / bottom gaskets
Requires electricity to operate lifting motor. If the aircraft hangar loses power, the door can be operated with a manual Hand Crank
With door completely open, the door folds into a 24" wedge
Example: Let's say your building opening is 12' clear, and you need a door clear opening 12' to maintain a 12' clear opening, you need to attach the door 24" higher than the clear opening.
Lose No Headroom, your building opening is 12' and your door opening will be 12' clear
The new " Lifting Straps " that raise and lower bifold doors have virtually made the bifold doors trouble free. Straps increase the speed of the door as it is opening. Straps will lift your door evenly at all times, no adjustment needed. Your straps will never have uneven spooling, binding, jumping, moving. Straps are self-contained and fully guarded for safety. Straps are safe rated for 29,000 pounds each (Cables are only 7,000 lbs. each). Straps are superior to cables. Your new lift strap bifold door will work for many trouble-free years of use.
Schweiss includes specs with each door and provides the weights, forces and hinge locations. Bifold door forces are less on the building structure because the doorframe when open sticks out 1/2 the distance, and the bifold doors have multiple lift points ( 4 ) that evenly distribute the weight of the door across the building structure
Schweiss automatic locks are a one step process. You hold the button to open the door and the autolatches release automatically and the door opens. Autolatches let you operate the door from one side of the door opening, saving costly mistakes. Unlike manual latches where people forget to unlatch before hitting the open button.
Bifolding doors are made up of two equal doorframes that hinge horizontally in the middle and at the top of the door. Bifold doors allows the doorframe to be shorter in closer to your building in the open position. The further the doorframes are away from the building structure the greater stresses are to your building. With a Bifold door the stresses are minimal, because a bifold door hangs out half the distance. The double set of hinges share the weight of your door which all equates to longer door life.

Vertical bifold doors are the most popular design for aircraft hangar doors. Vertical bifold doors are the least expensive door style to buy.
The best bifold door secrets are no longer secrets. People are catching on fast to the new strap lift design by Schweiss. Bifold Doors are proven and with the lift straps they are even better. Bifolds are very adaptable when it comes to attaching your door to the building structure. Only after I had used the new bifold door did I realize how unique of a design it truly is. All my neighbors are wanting my strap door.
Today's new lifting straps, that doors, have virtually made bifold. Your new lift strap bifold door will work for many trouble free years of use. Only after talking with many satisfied Schweiss Strap door customers did I realize Schweiss is truly the industry door expert.

...Nobody is returning your calls
...Not able to speak to an employee of the company... just an answering service
...Unable to get service
...Maybe it's used to
Take a trip down memory lane, few or more short years ago, door customers were losing deposits, company went belly up, leaving customers without service, doorframes tearing apart and no company left for support. How long does it take to forget about a $10,000.00 deposits lost? Shorted cylinders and the hydraulic power units!
Do your homework! Google around and understand the company you're dealing with!
How long has the business been in operation this time? What went wrong the first time? Same name? Same owners?
Do they actually manufacture their own doors or outsource everything?
Where did they say it was manufactured? Find out!
It speaks for itself when others DO NOT take " your " phone calls.
The Good News: It sounds like we finally have a delivery dare - Only to find out when the door was
delivered it was missing the major components, like the hydraulic cylinders and pump.
Hang onto your checkbook until you see the door... Seeing is believing!
"What good is a doorframe that's missing cylinders and pump?"
Pay only 25% down... Not a nickel more until the door shipment is complete, Including the Hydraulic Package.
The credit card companies will refund all of your money if you don't recieve your door on time!
Paying by personal check has more hoops to jump through to get a refund !
You know cheap and good don't always go in the same sentence.
