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 vary affordable prices.

 

 

 

 

 

 

How does the new "LIFT STRAP" work?

The strap wraps around the lift drum as the door opens, increasing
the circumference of the drum. The larger the drum’s
circumference, the faster the door opens. It’s ideal: the door opens slowly then picks up speed. It’s a clean, strong design. It’s quiet, it’s simple & the door opens faster.

 

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 6 years ago on a 40’ Schweiss Bi-Fold door on an airport hanger, Hector, MN, 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 50states, Europe and Japan.

 

How Do You Know The Straps Are So Reliable?

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+ years of conventional usage, without a single malfunction. The polyester material we are using has remarkable strength. That is why we confidently provide a 5-year warranty on our Lift Strap system. Like the ‘Energizer Battery’ our customers are finding Lift Strap systems keep working and working and working.

 

Can I Still Get Cables?

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, easier, and quieter.

 

Can I Put Straps On My Existing Schweiss Bi-Fold Door?

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.

 

 

FASTER

Straps will increase the opening/closing speed of the door because the strap wraps on the lift drum, the drum circumference increases, which in turn increases the “wrapping speed”.

 

SAFER

Definitely Safer – no frayed cable strands to contend with. 3” strap can lift 29,000 lbs where as ¼” cable can only lift 7,200 lbs.

 

FLEXIBLE

Straps are very flexible, which means longer life span than cable.

 

QUIETER

Straps are 100% quieter because it’s fiber against steel instead of steel against steel.

 

SMOOTH

Straps run smooth, so there’s no such thing as a “jerk” start.

 

ALIGNMENT

Straps never get tangled or crisscrossed.

 

LOAD

Straps evenly distribute the load on the door.

 

LIFE

Straps will outlast cables by three times the life of cables. The polyester straps are more durable than steel cables.

 

WARRANTY

We offer a FIVE YEAR WARRANTY on original lift straps.

 

CONVERTING

Schweiss has conversion kits available to adapt most present doors with cable lift to the new “Lift Strap”. Check with factory

 

STRAP STRENGTH FACTOR

Safety factor on the straps is well over 5:1 safety factor. Strength to weight ratio on our straps is extremely high.

 

• 3" Straps are rated at 29,000 lbs.
• ¼" cables are rated at 7,200 lbs.

 

Cables have been a standard with our Schweiss Bi-Fold Doors for many years because they really work nice. We provide you with a strong aircraft type grade cable, which provides security, safety and an even lift.
