Easy to maintain
Easy to install
Some manufacturers still continue to try and sell outdated cable
lift bifold doors - cable doors that not only require frequent maintenance
due to fraying, overwrapping or strands breaking , but also open much
slower, are hard to adjust, are not as reliable as straps, and are
noisier than liftstrap doors. Straps are a better design !
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.
Schweiss Lifts straps have proven to be by a far superior method of lifting any bifold door. Lift straps wrap on top of themselves by design, elimnating any common cable issues, like overlapping, rubbing and fraying. Lift straps are much quieter than cable doors!
"We were having trouble with frayed cables. I'd recommend liftstraps to anyone."
"Schweiss can convert any
outdated cable lift bifold door to a 'Lift Strap' bifold door"
"I do like the liftstraps.
they're a lot less maintenance faster and quieter."
The most obvious "market shaking" improvements for the Bifold Door is the addition of the patented lift-straps along with the new strap autolatch systems, two great features. Schweiss Lift Straps have revolutionized the door world by opening and closing much more quickly, quietly and effortlessly. Not only are they safer, but they're also easy to install and much longer lasting. Strap doors are leading the bifold door market !
Schweiss Doors have been doing doors for over 38 years,manufacturing two great styles of doors, Hydraulic Doors and "Lift-Strap" Bifold Doors. Schweiss Doors evolved with the times and greatly improved, creating a product that everyone is asking for!
Offsetting the cables during lifting of a bifold is a great concept, until your cables don't have the proper tension. Then you end up with messed up cables, unlike straps that wrap on top of each other. Tension is not an issue with lift straps nor do they get messed up. Straps are a perfect design... trouble free.
The only reason a cable door manufacturer would add more cable lifts to a door is because cables are not as strong as lift straps. More cable lifts means more maintenance and more expense - why fight the outdated cable concept and costs involved! Using more cables
may translate to less load per cable. But who wants more cables on a door if cables
are already known to cause issues when not maintained properly?
A cable is a cable no matter what sales pitch they throw at you. It's not about the cost of the cables... Maintaing proper tension or replacing cables is the issue. It takes time and labor to maintain or replace the cables and it's no easy task!
Cables are harder to work with!
Keeping proper tensioning of the cables is critical on any bifold door but the cable clamps make that very difficult. Cable doors are also slower, wear out sooner and are harder to replace. They require more maintenace and are not as reliable or quiet as lift straps. Schweiss Lifts straps are proven to be a far superior method of lifting any bifold door. Lift straps wrap on top of themselves by design, eliminating any overlapping issues and wear!
Schweiss has received thousands of calls from cable bifold door owners wanting to retrofit their outdated cable door system to the "Schweiss Liftstraps".
Loose cables cause problems
Cables require more maintenance meaning more down time
Cables wear out faster and fray
easily over time
Uneven cable wrapping causes problems
Cables wrap next to each other
and cause wear
Cables tend to walk all over the lift drum and cause problems
Schweiss Doors of Fairfax, Minnesota, USA have been on the market for over 38 years. We manufacture two great styles of doors, the New Red Power Hydraulic doors and the famous "Lift-Strap" Bifold doors - successfully for 20 years. What some people don't know is that they've evolved with the times and many improvements have gone into them, creating a product that everyone is wanting!
Market Shaking Invention
The most obvious 'market shaking' improvements for the Bifold Door is the addition of the patented lift-straps and the strap autolatch systems - two features not offered by any other door manufacturer. Schweiss Lift Straps have revolutionized the door world by opening and closing much more quickly, quietly and effortlessly. Not only are they safe, but they're also easy to install, and they're much longer lasting. It's a win-win for the customer and straps doors are leading in the door world. Word is spreading fast.
"Lift Straps" Tested and Proven
For years, bifold doors have been lifted and lowered by the conventional means of steel cables. Schweiss Bifold Doors have been using the popular, long-lasting lift straps for over 20 years- now 99 percent of our customers are demanding polyester lift straps for this function. Why? Because lift straps offer more lifting ability, won't fray or overwrap! The strength-to-weight ratio on straps is extremely high. The 3-inch straps are rated at 29,000 lbs, where 1/4" cables are rated at only 7,200 lbs. In addition, the safety factor on straps has well over a 5:1 ratio.
Everyone's Fed Up With Cable Doors
Cables are the old way. Everyone knows cables can over time have a tendency to fray. Frayed cables can break and doors can come crashing down on aircraft, machinery or even people. Cables require more servicing, are hard to work with and difficult to replace. Replacing cables with cables is a timely and costly expense, and can be a real safety issue if the cables are not kept in good condition.
Once You Try "Lift Straps" You'll Never Go Back to Cables
Schweiss's excellent success with the New Lift Straps has revolutionized the door industry. It's a no-brainer, why bother with cables, it becomes obvious. You'll understand why the New patented Lift Straps are the smarter way to raise and lower your bifold door, smoother, safer, faster, quieter. Like a customer once said:
Huge Advantage - 10 Year Warranty
The strap advantage is huge, straps are longer lasting, never rust, never tangle, are flexible, open a door faster and are 100 percent quieter than steel-on-steel cables. With lift straps, door owners get a "soft start" and "soft stop," adding to the life of the bifold door. Schweiss stands behind the "New Lift Straps" by carrying a 10-year warranty and straps outlast cables well over three times.
"How Can You Say that "Lift Straps are the Best?"
Schweiss has been receiving calls from door customers all over the country asking if they can modify or retrofit the "Schweiss Lift Straps" on their doors that currently are operating with a cable system.
"I know it's not your bifold door, but can we buy just the 'Lift Straps' and change my door over?"
"We have seen our neighbor's doors with your lift straps, would it be possible to convert/switch over my door to the 'Schweiss Lift Straps?'"
"I just purchased a new Schweiss Door six months ago with lift straps and we have two of your Schweiss doors with cables. Do you have a kit to put 'Lift Straps' on my older cable doors? We are really happy with the New Strap design!"
"I have an older model Schweiss Bifold Door, can we change over to
the 'Lift Straps', what's the cost, and is it possible?"
Schweiss has designed and figured out a way to modify any bifold that's ever been manufactured. Retrofitting an existing cable door over to the Patented Schweiss design "Lift Straps" has brought relief to the customer with the old vintage cable bifold doors. Finally the customers with cables can be at ease, they're able to do away with the antiquated cable lift design and retrofit any style door over to the latest and greatest Schweiss Patented "Lift Straps."

"You guys are good, thanks for the neat invention!"
"Should have done the strap conversion years ago!"
"If anyone asks, send'em my way and I'll be your salesman. I love my door now!"
We have introduced a new way to lift our bifold doors. Now available is our new, patented, "lift straps" that take the place of aircraft cables to raise and lower your door. The lift straps make our door Faster, Safer, Simpler, Easier, and Quieter than any other bi-fold door available to you on the market today. Schweiss Bi-fold Doors is constantly on the move, trying new and better ways. Our business Goal: Give the best money can buy at very affordable prices.
Schweiss designed and patented a custom made polyester Lift Strap that provides a new alternative to steel cables unlike any on the market to open bi-fold doors. The Schweiss Lift Strap is durable and lasts longer than steel cables. It requires less maintenance and it is very easy to replace. 99 percent of our customers are demanding the popular "New Lift Straps" on their Schweiss Bi-Fold doors.
How Does the new "Lift Strap" work? The strap
wraps around the lift drum as the door opens,
increasing the size of the drum. The larger the drum's
circumference the faster the door opens. It's ideal: the door
opens slowly at first and quickly picks up speed, a nice safety
feature. It's a clean, strong design. It's quiet, it's simple, and the door opens faster.
With the new "Lift Strap," Schweiss also offers a new strap tightener system which takes up
slack in the belting. This is a real nice feature for keeping the proper tension on the "Lift Straps"
All straps are polyester, they never rusts, making it more durable and longer-lasting than steel cables.
Straps are flexible, which means longer life span than cable.
Straps are 100% quieter and smoother running on the door.
Straps will increase the opening/closing speed of the door due to the size of the drum circumference. The door is opened
slowly at first then speeds up, a good safety feature. You get a Soft Start and a Soft Stop. It doesn't get any better.
Straps never get tangled or criss-crossed.
Straps evenly distribute the load on the door.
Straps have three times the life of cables.
When it comes time to tighten the straps, it's easier to use a ratchet tightener.
Cost of straps are competitive to the cost of cables.
NOW offer a 10-Year Warranty on original lift straps.
Schweiss has "Cable-Lift"-to-"Lift-Strap" conversion kits that adapt to most presents doors with factory.
Safety factor on the straps is well over 5:1.
Strength-to-weight ratio on our straps is extremely high.
3" straps are rated at 29,000 lbs / 1/4" cables are rated at 7,200 lbs.
That is why the Schweiss Lift-Strap System has a NEW 7-YEAR WARRANTY!!
When our patented lift-strap system became such a popular choice with door customers, it was
only logical that the competition would come out swinging, especially if a cable system is the only
system they offer. New Technology is wonderful, even in the door business.
• Cable systems are more durable, more reliable, and safer than straps.
• NOT SO! In fact, our "Lift-Strap" system beats the competition on all three of those
factors. However, Schweiss continues to offer cable doors should the customer want a
cable system. We believe in offering the option. You see that in many other features
available to our customers.
• Why bother with cables? Lift Straps are faster, safer, simpler, and quieter. End of debate.
• Our Lift-Strap system outlifts, outlasts outsells any cable system.
• Today, 99% of Schweiss Bi-Folds are ordered with Lift Straps.

All our straps are made of polyester material that has an indefinite working life. We did vigorous in-house
testing of the New Lift Strap system, the equivalent of 20 plus years of conventional usage, without a single malfunction.
The polyester material we are using has remarkable strength. That is why we confidently provide a 7-year warranty on our
Lift Strap system. Like the 'Energizer Battery' our customers are finding Lift Strap systems keep working and working and
The cable lift system is still the standard but that is rapidly changing. Already 80% of our doors get ordered with the new Lift
Strap System so it is obvious customers are catching on fast and for all the right reasons...faster, safer, simpler, easier, and
Yes, our older Bifold doors can be retrofitted with the Lift-Strap System. Yes, the Lift Strap System can work on Schweiss doors, depending upon the construction and mechanics of each particular door. However, I would not advise that it would work properly on EVERY bifold door, regardless of manufacturer. And there is no logical, or legal thought that we would endorse the use of our patented lift-Strap System on another manufacturer's door.
We have yet to sell a REPLACEMENT LIFT STRAP! They simply last, and last and last. And that is time, labor and $$$'s saved for the door owner. The 29,000-Lb. Tensile strength is a tremendous safety factor. That is why the Schweiss Lift-Strap System has a 10-YEAR WARRANTY!
The 'mechanics' of our lift-strap system are uniquely simple: As the strap wraps on the lift drum the door quietly opens quicker until it reaches the automatic stop position. Should you stop the door at any position, the door GENTLY comes to a stop. You get a Soft Start and a Soft Stop. It doesn't get any better.
The Lift-Strap System utilizes polyester material, which quietly wraps on a take-up spindle when the open or close button activates an electric motor.
Tensile strength of this poly strap is a whopping 29,000 lbs! The polyester straps never rust, making them more durable and longer lasting than steel cables.
Heavy duty poly strap replaces noisy, high maintenance steel cables. The patented poly strap system is unique with Schweiss Manufacturing. Virtually every Bi‑Fold door sold by Schweiss now leaves the plant with the LIFT‑STRAP system included.
Unheard of in the commercial door world is a 10-year warranty. But not for Schweiss Bifolds! Customer satisfaction has been so
universally supportive that Schweiss Doors, world leader in the manufacture and marketing of the famous Schweiss Doors, is now providing a 10-year warranty on our popular Lift-Strap mechanism

tensile strength, this nylon strap is virtually fail safe.
