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. Don’t you want to be a part of our door revolution?
The outstanding engineering, space saving quality, ease-of-use and increased productivity delivered by the Hydroswing® is now available through our new “game changing” door leasing program. This is an industry first for hydraulic doors, and Hydroswing® is proud to once again be in front of the pack.
So why should you lease a hydraulic door?
• Technology is moving and changing. Outdated bi-fold, slider and roller doors are quickly becoming obsolete (and in some cases, dangerous.) Even if you don’t have the cash on hand, you can still have the original and best hydraulic door on the market.
• If the door is used as a part of your business, there is the potential to enjoy a tax break because the lease payments will be fully deductible.
• The Hydroswing® door lease requires ZERO down.
• Low payments! This will free up your cash to invest back into your business.
• Total lease payments are almost always less than the original cash price of the equipment.
• Whether you choose a short-term lease (two to three years) or a long- term lease (four to five years), your payment will only be for the selected term.
• At the end of the lease and you’ll have a $1.00 buyout or FMV (Fair Market Value) buy out and the warranty that you had in place will assure your Hydroswing® door unit is as good as the day you first installed it and opened it.
Pre hung, pre assembled and ready to install, when fitted to existing buildings, the Hydroswing® single panel hydraulic door adds strength and valuable return to buildings which might have been previously seen as past their useful life. In the event you build new to replace the old, unbolt the Hydroswing® and simply refit your Hydroswing® to your new building, (or Hydroswing® can do this for you).
For ZERO down and payments starting as low as $49.99 per week, you truly can have it all: Single panel door simplicity, powerful and smooth hydraulic rams, solid tube steel construction, pre hung, no top or bottom rails, no sectional seals, no wasted wall or outside area conflicts, push button operation, exceptionally low operating and service costs.
Change your door…It’s easier than ever. Give us a call!
