WARNING: Schweiss does not recommend using your door as an extended work area (under the
door) or parking your expensive equipment or airplane under the doorway. Your door is the largest
piece of moving equipment on your building and can be dangerous. Keep the doorway clear.
The One-Piece® hydraulic door acts as a large moving wall that swings outward when opening,
requiring extra parking space as the door travels outward to the open position.
When operating the One-Piece® hydraulic door, you must clearly warn people. The moving door
swings outward, no parking in the doorway. Personal injury and property damage can result from a
At airports with hangars located on each side of the taxiway, keep the door open or closed (not half open) to avoid damaging wings as planes taxi by the front of your hangar door.
To avoid possible damage to equipment, vehicles, and airplanes, clearly label the doorway or ramp
area: "No Parking Area." By clearly marking the no parking area there will be less loss of valuable
parking area in front of your hangar/fly-in home/shop/warehouse/storage building.
Schweiss recommends that all One-Piece®
hydraulic doors have windows in the
doorframes. Windows will make any
obstructions in front of the door
visible to the operator before
opening the closed door.
Bifold doors have a huge advantage when opening; they start by raising upward, not outward, requiring less operating space in the front of your building. The area in front of your large door opening is very valuable space, the two-piece bifold allows more usable space in front of your door opening. Bifold doors are simply a real space saver.
Bifold doors have great design features built-in... tried and proven for many years.
Schweiss, the #1 Leader in One-Piece® hydraulic doors, is thinking of the
customer's best interest with this great product. The One-Piece® hydraulic
door will be at a 90° position when fully open. When Choosing a One-Piece®
door, take into consideration the following...
One-Piece® doors should have a slight downward slope when open to direct
moisture and water off the door sheeting. This prevents moisture and water from
seeping under the door sheeting and ruining the interior door insulation.
When you order your door, request a taller doorframe that allows you to open your door to the full clearance needed, yet the doorframe
will allow the door to have a slight slope to provide drainage necessary for the One-Piece® doorframe in the open position.
Go with the standard One-Piece® hydraulic door application lower the door to provide a slight slope downward, to avoid moisture problems.
When you lower the door it's important to be aware of the clear opening position of the door to provide the height clearances needed.
The sheeting on every Bifold door is flashed in
such a way it allows water to drain off the door
at any position. Water will not dam up on an open
Natural slope when door is in the open position.
No external truss to act as a dam - water flows off.
Water will flow off at any position.
Hydraulic doors are manufactured with a truss for support to provide strength/proper windloading to the door. It also minimizes the
door sagging in the open position. The truss will be placed on the exterior of the door or on the interior, it's the customer's choice.
An external truss is located on the outside of the One-Piece® doorframe 3 inches off the floor, ground level. The exterior steel truss is painted and is exposed to the weather elements.
External Trusses - Options
When you select the internal truss style, it gets placed on the inside of the doorframe. When the door is in the open position the internal truss will protrude into your clear opening. When you go with an internal truss you lose headroom unless you mount your door higher. Take into consideration that you may have to make your building structure taller to gain the headroom needed.
The One-Piece® doorframe in itself will have properly sized members to provide the necessary support for additional strength. On smaller size doors, the no truss look gains valuable headroom and gives you a clean look both outside and inside of the doorframe.
Bifold doors are manufactured with a truss for support to provide strength/proper windloading to the door. Bifold doors come standard with the internal truss for the 'Clean Neat Appearance'.
Benefits & Why - Truss is Located Near center of door (Up Higher)
Simplicity, quality, and strength are standard on every One-Piece® hydraulic door Schweiss manufactures. Today, Schweiss is the acknowledged No. 1 builder of One-Piece® hydraulic doors. Listening to our customers, and building quality and convenience into our products is what we do best. We have a talented team with more than 30 years of experience that welcomes new challenges. We have the product to show for it.
Do you need a one piece, sturdy, quick opening 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. There is also no headroom lost 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 walk-thru doors, a remote control, insulated windows, choice of colors, outer skin to match other buildings, etc.
The custom-built One-Piece® Hydraulic Door comes pre-assembled, pre-welded, and delivered prehung within its frame for ease of installation, giving the buyer/builder tremendous flexibility. That saves time and money.
Schweiss hydraulic doors are pre-built with a special bottom truss that provides added strength and rigidity, which is very important in high wind conditions. The doors are extremely weathertight.
Provides an extended canopy in the open position. Door swings outwards when opening requiring space for the door to travel.
The One-Piece® doorframe is opened with 2 heavy-duty hydraulic cylinders, one on each side of the door. 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) creating forces back to your building structure in the open position. The entire building structure must be designed to carry these loads.
Schweiss power units deliver a powerful, secure, and simple solution to raise and lower the door. Each door consists of only three major components: the door (prehung with frame), two hydraulic rams, and a hydraulic pump.
Hydraulic doors are designed with 1 set of heavy-duty hinges that carry the entire weight of the door.
"Good products are important. Good customers are even more important." - Let us help you with your door needs!
The bifold doors have been around for many years and the unique design has made Schweiss Bifold Doors the leader in the market. Schweiss Bifold Doors have design features built into the door that makes the bifold door stand in a class of its own. Listed below are some of the things that make the bifold a good choice.
The bifold doorframes are raised open with our patented heavy-duty lift straps. The nylon straps attach to the bottom of the doorframe at multiple locations to evenly lift the door. Bifold doors are lifted upward with nylon lift straps rated at 29,000 lbs tensile strength. These straps never bind or make noise like a cable lift door.
Lift straps wrap in a spool to raise and lower the door, increasing operating speed and making for a very quiet operating door. Lift Strap doors DO NOT require pulleys, which is a very nice design. Fewer parts, fewer problems, less maintenance.
Schweiss designed a new auto latch that uses a strap instead of steel cables. The Latch Strap is a great improvement for the bifold doors. The Latch Strap design sets us apart from others that are using cables to latch their door in tight. Gone are the cables and clamps!
Bifold doors have 2 sections, a top half and a bottom half, that provide many design advantages.
When your hydraulic door is opening or is in the wide open position, the door tends to pull away from the building at the hinge line and also puts stress on each building column where the cylinders attach. The building manufacturer/contractor/owner is responsible for ensuring that the building's structural design is capable of handling all the imposed loads that the door exerts to your door header, endwall, and building. Your building header/column design must meet standard deflection and strength criteria, both vertically and horizontally, to support the hydraulic door in all positions. Schweiss provides easy-to-read 'Necessary Specs Sheets' (A-1 through A-6) with each door, showing all the forces and building header requirements.
One-Piece® doors cantilever out from your building, exerting additional forces on the building header when in the open position. A One-Piece® door hangs out twice as far from the building as a bifold.
It's like a large airplane wing, the longer or further a doorframe sticks out away from the building at a 90° position, the more torque/stress it adds to the building header. The building header must be prepared to support the forces of your door in all positions.
The One-Piece® hydraulic door design is another alternative to the bifold folding door. Schweiss, the #1 leader in the door industry, offers customers choices when it comes to selecting doors for their buildings. Please read the following and let it be a helpful 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 design money can buy.
Bifold doors fold in half when in the open position, creating minimum force to your building's endwall.
Less stress on the building = Less stress on the door header.
Less stress on the doorframe = Less stress on the hinges.
Hydraulic doors are "One-Piece" that swing out when in the open position, creating forces to your building's endwall.
Comes Standard with it's own subframe for added structural support.
Hydraulic doors from Schweiss come with their own subframe that attaches to your building structure for added support.
The door is a large moving piece of equipment ATTACHED TO YOUR BUILDING and exerts large amounts of outward and inward forces. When your door is in the full open position, the door and subframe tend to pull away from the building at the hinge line, exerting considerable horizontal loads on the building structure.
Here are some facts to consider... All doors attach to the building and exert forces onto your building. Now add windy conditions to a door in the full open position. It will act like an airplane wing or a parachute and will carry the heavy forces back to your building. No matter what size door you have, all the weight is transferred back to your building. Schweiss has recommended safe operating parameters. Our doors will hold up, but will your building?
• "As far as I'm aware, hydraulic doors are more susceptible to wind problems when open than a bifold door."
WARNING: Improperly designed building and/or door headers can result in property damage, personal injury, or death.
CAUTION: Moving door swings outward, personal injury and property damage can result from a moving door.
WARNING: Schweiss does not recommend using your door as an extended work area (under the door) or parking your expensive equipment or airplane under the doorway. Your door is the largest piece of moving equipment on your building and can be dangerous. Keep the doorway clear.
