Customers that retrofitted their cable doors to liftstraps
Vero Beach, Florida airport packed up its hangar cable troubles with 14 bifold liftstrap door conversions
Pilots who rent and lease hangars at the Vero Beach Regional Airport in Florida are happy they no longer have to deal with cable lift doors. Fourteen 50 ft. x 20 ft. hangar doors there have had Schweiss liftstrap and autolatch conversions.
There's a marching song made popular during World War I whose lyrics begin with . . . "Pack up your troubles in your old kit-bag . . . And smile, smile, smile!"
“The City of Vero Beach was really, really happy with the whole 14 hangar door setup and how it went down. Schweiss has a better designed and cleaner operating system. By the third hangar we had a system set up to where we had all the structural components ready and our own welders and electricians ready to hook things up. We worked through all the small issues of adapting Schweiss equipment to an existing hangar door. We had great support from Jeremy at Schweiss Doors. By the time we were on our sixth hangar door we were a moving machine where everybody knew what they had to do. I would definitely recommend Schweiss doors and strap conversions to others.”

In retrospect, that's sort of what Jim Lavold, co-owner of James S. Lavold, Inc. did when his family-owned general contracting company completed 14 Schweiss Door liftstrap conversions on lease and rental Box and T-Hangars for the Florida city-owned Vero Beach Regional Airport. Now the city and aircraft owners are smiling, smiling, smiling because these 20-year-old cable-lift doors no longer pose a safety hazard and lift faster and much more efficiently.
"As an approved contractor for the FAA we do a lot of airport work and renovations. We also work on local government-owned and private hangars, hurricane repairs and things like that. We travel all over the country and work in all states. We did a project for the FAA renovating control towers in Hilo, Hawaii, St. Thomas, St. Croix and Puerto Rico," said Lavold.
Lavold's general construction business is located in Jupiter, Florida, about an hour's drive south of the southeastern coast city of Vero Beach. It's a place where you can experience beautiful beaches, luxury amenities and an easygoing lifestyle.
"We picked up on this Vero Beach project because it was something we specialize in anyway. There were other structural parts to this hangar project other than the strap conversions," said Lovold. "Vero Beach wanted the Schweiss conversion kits for their existing 50 ft. wide x 20 ft. high steel doors originally manufactured by, antiquated to say the least, Wilson Doors who are no longer in business. They had trouble with cables busting. On one occasion a cable snapped, and a door came down and hit one of the planes.
Lavold said the pilots are a lot more at ease with the strap systems modernized with automatic latch systems. He got to know a lot of the tenants and they were really excited about this city project that actually got through funding and worked out.
The City of Vero Beach approved the liftstrap conversion as part of its Airport Master Plan that projected a vibrant airport to meet the needs of the entire region. The electrical control boxes for the liftstrap doors were mounted just to the right of the bifold walk doors.
"The City of Vero Beach was really, really happy with the whole 14 hangar door setup and how it went down. Now the airport operations people who have taken over maintenance on these doors have said, 'There's nothing left for us to do - everything works great.' We had an independent on-site engineering inspection team that wrote me a nice letter commending us on how we took care of everything," said Lavold.
Once the Lavold team got working on the installation of the liftstrap conversion they breezed right through it.
"Schweiss has a better designed and cleaner operating system. At first, we had a learning curve on how to get through installing it. By the third hangar we had a system set up to where we had all the structural components ready and our own welders and electricians ready to hook things up," noted Lavold. "We worked through all the small issues of adapting Schweiss equipment to an existing hangar door. We had great support from Jeremy at Schweiss Doors. By the time we were on our sixth hangar door we were a moving machine where everybody knew what they had to do.
"I would definitely recommend Schweiss doors and strap conversions to others. We are actively seeking out new projects starting in Florida, but we will go anywhere. The City of Vero Beach still has two box hangars with bifolds on them that they want to switch over when they get approved for funding," added Lavold.
These two photos show the comparisons of the small Wilson Door gear box and motor (left) to the heavy-duty Schweiss gear box and motor that activate the drive shaft.

Low maintenance was the factor behind Colorado strap conversion
This Denver, Colorado manufacturing company 52' x 25' bifold door, built by another company, was upgraded with a Schweiss liftstrap conversion.
“I was very impressed with the development, design and smooth, well-engineered operating design of the doors and motors. Our end-user knows that the door is operating well and is secured well with the straps. Schweiss Doors also has the technical expertise that helped make the strap conversion go smoothly. Schweiss has a great track record and we know the quality of their system. Brent and their whole team at Schweiss were great to deal with. Schweiss is our go-to company for strap conversions.”
- Michael Pecora,
Senior Account Manager
Rocky Mountain Dock and Door
Four strong liftstraps powered by two Schweiss motors now lifts and lowers the bifold door smoother, faster and quietly. The company was having troubles with frayed cables that had to be replaced on several occasions.
After going through the hassle of replacing frayed bifold door cables a, manufacturing company in Denver, Colorado, along with their door partner, Rocky Mountain Dock and Door Specialties (RMDDS) decided it was time to contact Schweiss Doors for a liftstrap conversion on one of their 52' x 25' doors made by a different manufacturer.
Michael Pecora, a Senior Account Manager for RMDDS of Littleton, Colorado, stated; "This was the second Schweiss liftstrap conversion for this manufacturing company. We changed cables multiple times and it was time to do a strap conversion for them."
Pecora has been in the door industry for several years and has seen every type of door. He understands the quality Schweiss brings to any project.
"I was very impressed with the development, design and smooth, well-engineered operating design of the doors and motors," said Pecora. "Our end-user knows that the door is operating well and is secured well with the straps. Schweiss Doors also has the technical expertise that helped make the strap conversion go smoothly.

No more hearing the 'Pop and Crack' of cables . . .
New Georgia hangar door gets 'royal' uplift with Schweiss liftstrap conversion
This new hangar at LaGrange Callaway Airport in Georgia is clean from top to bottom. The 70' x 18' door built by another manufacturer recently went through a Schweiss Door straplift conversion.
Georgia Crown Distributing Company leases a virtually new 80' x 100' hangar at the LaGrange Callaway Airport that went through a royal uplift with a Schweiss bifold liftstrap door conversion even though the cables from the other manufacturers door weren't even rusted or frayed yet.
Corporate pilot, Chuck Newman, a pilot of 23 years and with a background in construction, didn't like the door supplied by another manufacturer, not in the least bit.
“We've had cable doors in the past and I know how difficult it is to keep cables changed out. It seemed like we would get three or four years out of a cable and then they would start to fray and they are difficult to adjust. The door we had was a lower end door so the shaft diameter was pretty small and there were a lot of things about it I didn't like. The door with straps is now unbelievably quiet. We were always hearing the cables pop and crack. This door is now almost perfectly silent. It actually basically turned into a Schweiss door in every respect except for the framework itself.”

"It was definitely my idea to do a straplift conversion," said Newman. "We had originally spec'd the hangar for a Schweiss door, and then they showed up with this other door. I wasn't a fan of it, and it had only been in service for about three months. This (conversion) was the easiest way to beef it up and make it last the life of the hangar."
You might think this would have been a hard sell for corporate approval, but Newman said he wouldn't accept it any other way and would have rather sent the door back, but they didn't want to do that.
"We've had cable doors in the past and I know how difficult it is to keep cables changed out. It seemed like we would get three or four years out of a cable and then they would start to fray and they are difficult to adjust; not something I wanted to deal with. The door we had was a lower end door so the shaft diameter was pretty small and there were a lot of things about it I didn't like. While doing the strap conversion we redid the drive shaft, so that beefed it up. I also didn't like the overcentering mechanism that it had - it had a chintzy little winch device that locked the centers down; was really hard to deal with. When they did the strap conversion they did the automatic centerlock system as well. The Schweiss automatic latch system replaced a very manual system prior to this."
Ten strong liftstraps, each capable of lifting 29,000 lbs. now lift the door faster, smoothly, safely and quietly. A remote opening system gives the pilot the option to open the door from the cockpit of the plane.
It actually basically turned into a Schweiss door in every respect except for the framework itself," noted Newman.
Danny Hutchinson, Superintendent at Astra Construction Services in Woodstock, Georgia, placed the order for the conversion on the 70' x 18' jet hangar door and noted that the process of replacing the cables went very well. Hutchinson said Newman, who ran the hangar for Crown Royal, just wanted Schweiss liftstraps on it to replace the cables on this other manufacturers door as a maintenance and upgrade. The door is also equipped with a remote opener.
"The liftstrap conversion directions were good, but we also followed a YouTube video that showed how to install the conversion. We were doing some stuff off and on; one man probably worked on it for a day and a half with a little help here and there. The hangar belongs to the Troup County Airport Authority and leased to the Crown Royal distributors. It's a nice looking system that works fine and has an automatic locking system," said Hutchinson.
LaGrange Callaway Airport Director of Maintenance, Larry Nommensen, said the pilot, Chuck Newman, had seen Schweiss straps on other hangars that he deals with. He said the straps look very nice, work well and run smooth.
The corporate hangar, that houses a Learjet 75, has many amenities such as a kitchenette, two offices, Schwank radiant heaters and a maintenance shop.
Newman said he became familiar with the strap conversion after talking to Mike Schweiss at the Oshkosh, Wisconsin airshow and also at the National Business Aviation Association Convention held in Las Vegas. He also looked at another hangar at the LaGrange Airport that had a Schweiss strap conversion.

Loenbro Flight Department pilot has strap conversion done for his peace of mind
This Cessna Citation V, flown by Mark Haakenson of Loenbro Flight Department in Great Falls, Montana, sits a lot safer in its hangar now that the 55' x 15' bifold door has a Schweiss liftstrap conversion.
When pilot Mark Haakenson's employer at the Loenbro Flight Department purchased a hangar at the Great Falls International Airport in Montana all it took was a quick look at the frayed cables on the 55'x15' door made by another manufacturer to convince him that something needed to be done.
"My first experience with Schweiss Doors was back in Willmar, Minnesota where I was working as a contract pilot. An employer of mine had built a hangar with, I believe, an AeroLift door - it was a brand new hangar with brand new doors. AeroLift came out eight or nine times and couldn't get the door rigged up right. I was working in the hangar and one of the Schweiss technicians was on the field doing some work on somebody else's hangar. I went over and chatted with him and asked him if he could take a look at our door. Well, it only took him a half hour and he had it working great. We had a Schweiss technician rigging an AeroLift door and he did a better job than AeroLift did," chuckled Haakenson.
He said the next time he had anything to say about hangar doors or lift systems, he was always pointing toward Schweiss. Going forward, Haakenson moved out to Great Falls seven years ago where he worked for a company flying their Beech jet. Their hangar had a cable door on it that Haakenson said had no identification on it to tell him who it was made by - it wasn't a Schweiss door.
“When my current company purchased this hangar from the old owners one of the things I told them was they needed to calculate the expense of replacing the cables and pulleys with a liftstrap system from Schweiss. I told them I wouldn't tug an airplane in under that door in the shape it was - the cables had been replaced two years earlier and they were fraying enough that you would catch them on your coat as you walked by. In a month or two we had ordered the liftstrap system with the straplatch option as well. I love it; I've got people that come in here that want to see how the straplatch system works because I keep on bragging on it. It's a great system, the door goes up faster, it's quiet and more secure; the old door had three 3/8th" cables, now I have five nylon straps so I feel a lot better walking under the door.”

"While I was here we replaced the cables once. When my current company purchased this hangar from the old owners one of the things I told them was they needed to calculate the expense of replacing the cables and pulleys with a liftstrap system from Schweiss," said Haakenson. "I told them I wouldn't tug an airplane in under that door in the shape it was - the cables had been replaced two years earlier and they were fraying enough that you would catch them on your coat as you walked by.
"In a month or two we had ordered the liftstrap system with the straplatch option as well. I love it; I've got people that come in here that want to see how the straplatch system works because I keep on bragging on it. It's a great system, the door goes up faster, it's quiet and more secure; the old door had three 3/8th" cables, now I have five nylon straps so I feel a lot better walking under the door."
At first Haakenson said he was going to hire a contractor to install the liftstrap system with automatic latches and a remote opener. He called Schweiss Doors and asked how hard it would be to do the conversion; they convinced him to give it a try. His oil and gas company has a ton of welders, so he showed his project managers what he wanted to do. They put it together with no problem at all.
"I think the biggest thing I like about the door now is the sense of security; it lets me know the door is safe. The other is the convenience of the remote and the strap latch; it's fantastic. Every other hangar that I've used you had to go through this process of trying to get the door latched properly. Now I just have the remote in my pocket and it's a done deal, it's slick," noted Haakenson.
Haakenson said his hangar door gets used two or three times a week. He flies a Cessna Citation V, a turbofan-powered small-to-medium-sized business jet.
Pilot Mark Haakenson gives the thumbs up to liftstrap conversion. Frayed cables on the existing 55'x15' door made by another manufacturer convinced him that something needed to be done before the door came crashing down on him or on the company's Cessna Citation V.

The bifold door, made by an unknown manufacturer, now has five liftstraps, an automatic latch system and remote opener. The hangar gets opened two or three times a week.
The cables on this door, prior to the liftstrap conversion, had just been replaced two years earlier and were already fraying. He now says the door opens faster, quieter and locks securely.

Reliability was key factor for hangar door owner to convert to liftstraps
Dave Frederikson's old cable lift bifold door took on a new improved look and safer method of lifting his 60' x 20' hangar door at the Chippewa Valley Airport in Eau Claire, Wisconsin. He installed the system himself and said the directions were easy to follow.
If you were to put the justification in one word for why Dave Frederikson of Eau Claire, Wisconsin decided to retrofit his 60' x 20' cable lift hangar door to the Schweiss liftstraps and autolatch system, that word would be "safety."
“I've always been impressed with the straps and always have been concerned about the safety of a cable versus a strap. I finally got the wherewithal to do it. Other than my cable system was 20 years old, I didn't like it and I didn't want to put in a new door to replace this other manufacturers door. Now that the door is up, I believe it has to be much safer because I have eight straps holding it up rather than six cables. I have to believe even if I have a failure of three or four straps that the door would still hold up. The straps are easy, they don't look ratty and the insulation isn't going to fall apart on the doors.”

"I've always been impressed with the straps and always have been concerned about the safety of a cable versus a strap. I finally got the wherewithal to do it," said Frederikson. "Other than my cable system was 20 years old, I didn't like it and I didn't want to put in a new door to replace this other manufacturers door. Now that the door is up, I believe it has to be much safer because I have eight straps holding it up rather than six cables. I have to believe even if I have a failure of three or four straps that the door would still hold up. The straps are four times stronger than a cable."
His introduction from the cable to liftstrap conversion system came via seeing Schweiss Doors displays at the Oshkosh, Wisconsin AirVenture Fly-In & Convention over several years. There was also a person he met there that got a new door from Schweiss. That, followed up with a visit to the Schweiss Doors website, convinced him to go with the conversion on his hangar door at the Chippewa Valley Regional Airport.
Frederikson said he had no problem following the easy-to-install very well done directions that came with the conversion kit. He used a local welder to put in additional bracing and to weld the gearboxes and bulk heads to the existing door. He said the whole process took about a week to cut the old stuff off and get it operational. He also said he very much appreciated the help he got from Schweiss Doors employees, Jeremy Rieke and Neal Brooks, in the ordering and parts departments.
"I think they are faster than a cable door, just looking at it, it seems more secure and safer. The physical appearance of it is well engineered. I know that by having put it on myself it is durable, it weighs a lot and mechanically it's quieter. I have two gearboxes instead of one smaller unit from the original door. It certainly is smoother and I have a lot more trust in it. All-in-all it's worked out well."
Frederikson said his door already had an automatic latch system with locking arms on it. With a little modification he was able to keep using the same arms and said doing the conversion wasn't difficult by any stretch To dress up the appearance of the interior of the door Frederikson put the new Schweiss interlocking insulation panels on the door.
"I've always appreciated the engineering of the straps. I think they are going to prove to be a welcome addition. The straps are easy, they don't look ratty and the insulation isn't going to fall apart on the doors," added Frederikson.
This is how his bifold door, purchased from another manufacturer, looked prior to the conversion. In addition to the cable to liftstrap conversion, Frederikson removed his fiberglass insulation and replaced it with the new Schweiss interlocking insulation panels to give the door a new clean look.
Chippewa Valley Airport, Wisconsin
Chippewa Valley Regional Airport is a public use airport in Chippewa County, Wisconsin. The airport is owned by Eau Claire County and is located three nautical miles north of the central business district of the city of Eau Claire.
It is the largest airport in the 30-county northern Wisconsin area and serves primarily the Chippewa Valley region, operating on a budget approved by a commission equally representing the interests of Chippewa, Eau Claire and Dunn counties.
The airport is mainly used for general aviation and business travel; the Eau Claire-based Menards Corporation uses CVRA to base their fleet of aircraft to serve their stores throughout the Midwest. It is occasionally used as an alternative-landing site for flights bound for Minneapolis-Saint Paul International Airport.
Chippewa Valley Regional Airport covers an area of 1,100 acres at an elevation of 913 feet above mean sea level. It has two runways: 4/22 is 8,101 by 150 feet with a concrete surface and 14/32 is 5,000 by 100 feet with an asphalt/concrete surface.
For the 12-month period ending December 31, 2015, the airport had 22,549 aircraft operations, an average of 62 per day: 87 percent general aviation, 12 percent air taxi, less than 1 percent military and less than 1 percent scheduled commercial. In October 2017, there were 87 aircraft based at this airport: 60 single-engine, 10 multi-engine, 15 jet and 2 helicopters.
Hangar 54 Grill offers a diverse menu with many locally-sourced, made-from-scratch items with a full service bar overlooking the runway. Private meeting room space is also available.
It is included in the Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021, in which it is categorized as a non-hub primary commercial service facility.
Having the cables removed and the conversion completed, Frederikson has peace of mind knowing that straps are much stronger than cables.
