Lift Straps
We have introduced a new way to lift our bi-fold 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. 80% of
the door manufactured for Schweiss Customers
are demanding the popular "New Lift Straps".
Specially Designed
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.
Strap Tightner
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"
The Real Advantage
Straps vs. Cables: "The Real Advantages"
All straps are polyester, which 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 will outlast cables by 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.
We offer a 7 Year Warranty on original lift straps.
Schweiss has conversion kits available to adapt to most present door with the
cable lift to the new "Lift Strap". Check with factory.
Safety factor on the straps is well over 5:1 safety factor.
Strength to weight ratio on our straps is extremely high.
Ex: 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!!
Something Worth Reading
About Lift Straps
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 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 out lifts, out lasts and out sells any cable system.
• Today, 80% of Schweiss Bi-Folds are ordered with Lift Straps.
• Since we introduced our Lift-Strap package, cable systems have become hard to
sell.
• Faster - Gear Ratio changes as the door opens.
• Safer - 29,000 lb. Tensile strength, compared to 7,900 lbs. Cable.
• Easier - Install a strap, or install a cable. What a difference.
• Simpler - Never will lift straps tangle. How can they lift?
They wrap onto themselves.
• Straps out last cable.
• Straps are very low maintenance.
• Straps are clean, neat looking. No abrasive strands.
• Straps will stretch with use, so we designed a simple strap tightener.
Give it one or two clicks and your strap is tight again. How simple does it get?
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 working.
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 quieter.
Yes, our older Bi-Fold 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 bi-fold
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 7-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.
• Smoothest door opening mechanism I've ever seen.
• A really trouble free lift system.
• Anything is better than those cable doors.
• We installed lift straps 3 years ago and have never had to adjust the straps.
• I'll never buy a cable door again.
• We feel the lift strap system is much safer.
• I don't know why anyone would buy a cable when you can buy lift straps.
• When my neighbors seen my door, they want the same style also
Now you understand why we are proud of our bi-fold doors
and our unique lift-strap system. It's simply a BETTER BUY.
Thank you for your interest in Schweiss Bi-Fold Doors.

Strap Tightener System
Used to take up the slack
in the belting.
3" Strap
Safety Shield
Patented
(U.S. No. 6,199,617)
The Lift-Strap System utilized 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 rural Minnesota plant
with the LIFT-STRAP system included.

• Safer
• Simpler

Why?
1. Why read by candle light when there's light bulbs?
2. Why watch a Black & White T.V. when there's Color?
3. Why use Cables when there's Schweiss Lift Straps?
Where Are Straps Used?
1. Trucking / Tie down loads
2. Ships / Barges / Cranes
3. Search & Rescue Missions
Why Did We Switch?
Because customer satisfaction is our #1 mission. And when
Customer after Customer comments, "Your lift strap system is
perfect", about all we can say is THANK YOU! But we'll keep trying
to make it even better! And what better proof of a "better mousetrap"
than satisfied customers. Since the first Lift Strap system was
installed 8 years ago on a 40' Schweiss Bi-Fold door on an airport hanger Mike Schweiss reports:
 |
We have yet to hear of a failure! |
|
We have yet to do a replacement! |
|
We have "Lift Strap" systems in place on Bi-Fold doors in all |
50 states, Europe and Japan. |
• FASTER
• SIMPLER
• QUIETER
• PROVEN
• SAFER
• EASIER
• SMOOTHER
When Schweiss Manufacturing switched from conventional steel
cables to a patented, polyester lift-strap system for their popular
Bi-Fold Door, their entire business took a quantum lift also.
