Everything you need to know about Hydraulic Doors for Aviation, Agriculture, Industrial & Architectural use

Hydroswing Then and Now – Always Raising the Bar Higher

 

 

Hydraulics are always evolving. Hydroswing® is always evolving. Back in the day, operators turned a crank to raise and lower cable lift dump trucks.  Enter hydraulics and the dynamics of the dump truck are transformed.  A horizontal hydraulic ram and lever simplified and changed an entire industry. And so it is with the Hydroswing® single panel hydraulic door.  It won’t be long before slider, roller and bifold doors go by the way of the cable lift dump truck. Door systems have been transformed by the power of hydraulics: simple and reliable solutions for any and every door problem.

 


Hydroswing® was born in agriculture. Farmers needed easy, reliable doors for sheds, barns and production facilities.  They didn’t want to worry about pulleys, straps and broken parts. The early Hydroswing® doors were medium (comparatively speaking) in size, yet always extremely efficient, and farmers believed and trusted the fluid power and simplicity of hydraulics. Hydroswing® was on the move.

The DNA of the modern day Hydroswing® was built in agriculture but quickly evolved to include all sectors. With over 7,000 sold to date in aviation, agriculture, industry and architectural market sectors, the future holds endless possibilities.  Technological advancements and cutting edge design have made Hydroswing® the industry leader.  Today’s Hydroswing® single panel hydraulic door replaces almost all door systems with strength, efficiency, value, aesthetics, reduced maintenance and versatility.

Over the years, as budgets around the world became leaner and with higher sensitivity to re-use and maintenance, Hydroswing® found a way to produce the same high quality doors at a lower price. In all critical environments, less moving parts usually means greater ease of use, less cost of ownership, lower in life service costs, ease of local repair in the event of failure, simplicity of understanding and ease of replacement of old and unserviceable former doors.


The Hydroswing® single panel door system, like no other on the market paves the way to expand and grow in a market which is late to change and react.  By changing the way new and existing buildings function via implementation of the Hydroswing® it will lead to new efficiencies in building and wall designs.

Once produced only in the United States, Hydroswing® is now fully fabricated and engineered in ISO 9001 facilities worldwide. Evolution is a natural process, and Hydroswing is a natural selection for all your door needs from 10’ wide to 150’ wide and now up to 45’ tall.
 

 

 

 

 

 

 

 

The History of Hydraulics – Still Going Strong

The word “hydraulic” comes from the Greek ‘hydra’ which refers to water and ‘aulos’ which means pipes.  Science historians believe that hydraulics (in an extremely basic form) originated in the Greek civilization two millennia ago.  The mathematician, Archimedes, reasoned that “a floating or immersed body must be acted upon an upward force equal to weight of the liquid that it displaces.”

As time passed, science improved, technology was beginning to take shape and ways to effectively use hydraulic energy were being discovered.  It all began with how water physically behaved at rest or in motion, and evolved from how to generate power with water at the source, to how to generate power at different points of use. Soon, the concept of transmitting power by putting fluids under pressure changed the face of engineering.  

In the late 17th century, the study of using oil in hydraulics started to get some legs. French mathematician, Blaise Pascal, created at law in fluid mechanics stating “that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure variations (initial differences) remain the same.” This became known as Pascal’s Law and created the fundamentals for the science of hydraulics.

 

Enter English inventor Joseph Bramah. Based on Pascal’s Law, Bramah invented the hydraulic press. His understanding of the relationship between force, pressure and area forever changed engineering and industry.  Bramah demonstrated that pressure throughout a closed system is constant and he was granted a patent for his product in 1795. By the time Britain’s industrial revolution hit in 1850, hydraulics were being used in a multitude of industries.  The twentieth century saw fluid power through hydraulic replacing electrical systems and the rest, as they say, is history.  


Greenham Common used hydraulic doors to seal in safety and seal out nuclear blast. Opened in 1942, it was used by both the Royal Air Force in WW II and most famously by the US Air Force as a major Cold War Nuclear Strike Base. From late 1967, Greenham Common was used for NATO operations in deterrence of the Eastern Block countries. The missile bunkers seen here were designed with their hydraulic doors to withstand the local airbursting of a point strike on the West’s front line deterrent from the East, showing the unique ability of the Hydraulic door system to carry strength and integrity to such a level… and they are still in existence today for all to see as part of the Cold War history.

 

Today, Hydroswing® is proud to be the pioneer in hydraulic doors. Our superior technology has allowed us to engineer single panel hydraulic doors that replace doors with mechanical and electrical drives.  We have taken hydraulic door systems to the next level and are changing the world one door at time.
