Some manufacturers still continue to try and sell outdated cable lift bifold
doors - cables not only require frequent maintenance due to fraying,
overwrapping or strands breaking , but also only rated for 7,200 Lbs. each,
open much slower, are hard to adjust, are not as reliable as straps, and are
noisier than liftstrap doors. Straps are a better design!
Ninety-nine percent of Schweiss bifold door customers are now demanding the
stronger, patented polyester lift straps. For years, bifold doors were
lifted and lowered by the slow, conventional means of outdated steel
cables, that have a tendency to fray, overwrap, and break.
Other manufacturers try to put their spin on cables, but the truth remains that cables are not easy to work with
and the life expectancy is shorter compared to lift-straps. Cables operate on a fixed speed, whereas straps lift
your door faster and are exceptionally much safer!
New clean / simple design!
Strap Latches secure the door in the open position
• Firmly hold the door against your building in the closed position
• Adds protection from wind gusts in any position during operation
• Firmly locks the door to the building when closed
• Secures the door when opening
• No more cables
• No more pulleys
• No more chains
• No more sprockets
• No Widgets
• No linkage rods to mess with
• Quieter Operation
• No additional motors needed
Strap Latch adds protection from wind gusts while operating
Strap Latches secure the door when closed
This is what every door owner wants and needs. Unlike other latch mechanisms, the new design will firmly hold the door against your building in all positions; securing the door when open/partially open and will firmly lock the door when closed. It will offer added protection from wind gusts while the door is in any position during operation.
Bifold Doors have been around for years, but thanks to Schweiss Doors foresight, they are 1000 times better now! Calls are coming in from owners of all styles of cable doors wanting to convert to straps.
Maintenance has dropped off to nothing with the Liftstraps and Latch Straps
• Liftstraps make the door easier to look over for potential problems
• Straps certainly require alot less maintenance
• Virtually no adjustment necessary with straps
• No more worries about cables fraying or cable clamps slipping
"Cable where just a maintenance nightmare. We were having a lot of problems keeping the cables adjusted and
replacing broken cables. It was really hard to tell when a cable was slipping, and it would go from looking
perfectly fine to fraying almost immediately."
No matter the make, model or manufacturer of the door you own,
you can see the obvious: Schweiss Liftstrap Bifold doors are a safer,
faster, and better solution than outdated cable lift doors.
"Schweiss can convert any
cable bifold door to a
'Lift Strap' bifold door"
"We were having some trouble
with frayed cables.
I'd recommend liftstraps to anyone."
"I do like the liftstraps.
They're a lot less maintenance,
faster and quieter."
"We also like the convenience
of the liftstraps being faster than
the old cables on our door."
"The straps run the door up
faster and safer and I like the
"The decision to get liftstraps
on my bifold door was more of
a safety issue for me."
"We're having zero problems
now with the liftstraps."
"A lot of guys are coming to look at
our door. I'm sure you'll be selling
more Lift Straps, we like 'em!"
"I can't say enough about
your liftstraps, I wish I'd
done it originally."

Nothing like it on the market
Must be strong
The door weight and hydraulic forces pull down on hinge when door is opening
"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 doorframes are designed with triple push tubes that are tied directly into the wrap-around hinges that connect each vertical push tube directly to the header tube. The advantage of triple push tubes is that forces of hydraulic cylinders are evenly distributed to the doorframe and the wrap-around hinges.
|• "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 your hinges. |
|• "Nothing on the market that even comes |
close to the Schweiss hinge design."
Schweiss is the only manufacturer to offer hinges that can be greased from underneath the door without removing the top weather seal.

from underneath the door
Others try to get by
using bushings and
welding the hinge pins
in place . . . Not the Schweiss way!
This Schweiss hydraulic door was designed for 175 mph windload and equipped with a hydraulic 2-speed valve for smooth operation that includes a 12 volt backup system in case of a power outage. The door has the newly designed and patented wrap around hinges that can be lubricated from inside the building, making maintenance quick and easy!
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.
