The Bifold Hangar Door… Inferior by design

Technology has moved on from wires, cables, pulleys and straps. The world is becoming simpler and safer. Hydraulic doors will soon be the only logical choice for not only aviation, but for agriculture, architecture and mining sectors as well. From a safety perspective, by its very nature, the bifold door is outdated and potentially dangerous.  We recently completed an installation in the U.K. that demonstrates exactly why bifolds are an endangered species.  

 

We were called us about replacing two doors at the Brighton Airport (Shoreham-by-Sea, West Sussex, United Kingdom). The existing bifold doors were only three years old and one (at the Real Flying Company) had fallen down completely as a result of wire cable failure, the other (at Advance Helicopters) was an accident waiting to happen. Having narrowly missed the operator on site, the owner wanted to quickly dispose of a potentially dangerous situation and start new with a stronger, simpler, safer hydraulic Hydroswing® door solution. The operationally unsound bifolds were products of Express Hi Fold Ltd. (a known knock off of an American product by a similar name) and rely on wire cables connected to a chain driven winding axle drum.  With such a high number of moving parts, the risk of failure increases exponentially.

 

 

 

 

 

Hydroswing® was an easy choice for Apollo. Our hydraulic Hydroswing® door is a single panel, has greater strength through design and steel size, 70% less moving parts than the substandard bifold, and is now manufactured in several ISO 9001 facilities around the world, including Great Britain. The door dimensions at Shoreham 60’(18.28m) x 17’(5.18m) and 55’(16.76m) x 17’(5.18m) respectively, were quickly retrofitted with Hydroswing® which in turn immediately provided an additional three feet of tail clearance. Our zero drop two-way Hydrolok™ system also assures the door will never fall should there ever be a loss of hydraulic power.

 

 The bifolds that were torn out have no frame so the retro fit was simple. (It usually only takes two days to fit any opening.) The Hydroswing® is built to fit easily pre hung in its own frame directly into the rough opening and welded straight to the header and uprights of the building. The vastly superior Hydroswing® also provides peace of mind when it’s open, closed or moving: No wires. No straps. No chains with axles or cogs. Most bifolds require supplementary contraptions to hold them in place while closed. Not the Hydroswing® - with almost 100% seal-ability, the door remains tight. These two Hydroswing® doors at Shoreham also incorporate our patented Bow Truss Technology, providing leading edge strength and aesthetics worthy of an architectural install. This special truss also gives “at a glance” certainty of the origin and integrity of this latest generation Hydroswing® hangar door system.

 

 The current trend shows more and more aviation facilities stepping away from the old and now outdated bifolds in favor of the safety, simplicity and effectiveness of Hydroswing®. (Note: A number of the well known Bifold manufacturers are trying to copy and emulate the Hydroswing® design. Keep in mind if it’s not from Hydroswing®… it’s not a Hydroswing®.) We proudly boast over 7,000 Hydroswing® in service and a growing number of bifold replacements and retrofit orders are coming in on a regular basis. Hydroswing® continues to change the general aviation hangar door sector for good. The Hydroswing® hangar door systems are the right choice:

  • 70% less moving parts
  • 100% improved seal-ability
  • Almost Zero Maintenance
  • Zero Drop Safety with Hydrolok™
  • 1m (3’.0) recovered clear height
  • 100% better looking
  • Adds value to the building
  • 90 MPH wind rating standard
  • Full drawing pack per door
  • Patented Bow Truss Technology
  • 2 day retro fit on most buildings

The Original Hydroswing - Still the First, Still the Best

"Original" is defined as "present or existing from the beginning; first or earliest." and "something serving as a model or basis for imitations or copies." In the world of hydraulic doors, original can simply be defined as "Hydroswing." Since its creation in 1996, the Hydroswing® has been the benchmark for single panel hydraulic door systems. With necessity being the mother of invention, it was only a matter of time before bifold and roller doors would be eclipsed by hydraulics, a more efficient option for aviation, agriculture and architecture sectors. Hydroswing® brought the revolution and continues to be the leader.

 

Being the original hydraulic door manufacturer, we have always had an outstanding product. Nonetheless, we had a few stumbling blocks in our early production structure and knew we had to make some changes and come to our buyers more cost effectively. Hydroswing® is now being manufactured in ISO 9001 approved global manufacturing plants allowing for a 25+% price cost reduction in the final product. We are hitting the market again with the original high quality hydraulic doors, but at a bifold price, square foot for square foot. We are changing the dynamics of the marketplace.

Hydroswing® door copies, usually offered by bifold manufacturers, are popping up regularly. But, keep in mind that if you're not buying directly from Hydroswing®, it's NOT a Hydroswing®. Currently, we are the only distributor of the original Hydroswing®, and anything else is just a knock-off. Look for our "H" logo... if you don't find it, it's not ours.

 

We'll custom manufacture a door in any size as large as 40' tall and 150' wide. Our customers are choosing the Hydroswing® door for security, wind load strength, and overall building use and efficiency.

 

More Originals to Come...

The fact that the Hydroswing® Door is pre hung in its very own load bearing frame, allowed for an evolution. Following many requests for the growing use of ISO shipping containers for architecture, military and commercial industries, the patent pending "plug and play" door for ISO Containers emerged. The ISO DOOR™ simply locks onto the side, ends or links between side or ends of the the ISO shipping container utilizing the ISO "tandelock" quick attach. This is the "missing link" for container shelter doors for mining and military operations as well as many other industries. It also allows instant re-purposing of the old shipping container and effective building of shipping container shelters of any size. With Hydroswing® providing a superior door solution, there are now endless possibilities for mobile shelters for UAV's, mining, exploration equipment and disaster relief operations.

 

The original Hydroswing® product now serves many sectors and sizes. A growing number of door problems are solved with simple, efficient and strong product. The design team is now located in various countries, all with valuable input to the Hydroswing® brand. Building on 10+ years of design and engineering expertise from the USA, Hydroswing® continues to bring the hydraulic overhead to the next generation.
