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

Hydroswing – The Basics

Hydraulics are the foundation of the future. The simplicity of liquid fluid power moving heavy objects is a solution that fits into all sectors of building and manufacturing. Hydroswing is the original and still the best hydraulic door on the market and we have a profound understanding of what it takes to create an extraordinary product.

 

 The anatomy of a Hydroswing Door

 

A fundamental feature of any hydraulic system is the ability to apply force or torque multiplication in an easy way, independent of the distance between the input and output, without the need for mechanical gears or levers. This concept, used in large machinery worldwide for decades, is at the core of the Hydroswing hydraulic door. The Hydroswing® is operated by two dual-acting hydraulic rams powered by a single or three-phase motor and pump, and all of our electrical controls are UL Certified. This in itself provides an extra layer of safety because the Hydrowswing® is impossible to operate without access to the control unit, making it far more secure than other types of doors.)

 

Simple, powerful and secure

Our single panel doors are fabricated and welded to ISO 9001 and American Welding Society D1.1 standards and each is stringently audited for strength and quality assurance. The Hydroswing is always pre hung in its own frame of tube steel. Unlike inferior products on the market, the Hydroswing is an industry leader in post fabrication shot blasting. We use a Carboline Carboguard 890 Epoxy paint finish with a certificate of conformance being supplied with each door to ensure the integrity of this work.

Simplicity, strength, ease of use and reduction in moving parts, plus use of cladding (which makes the door match the thermal characteristics of the building) are among the top reasons customers are making the switch to Hydroswing®. The sophistication of single panel hydraulic doors is now part of everyday door use for facilities large and small across the U.S. and around the world.

 

The Hydroswing finds itself in all kinds of places!

Cost effective, safe, and accommodating in sizes up to 150’(45.0 m) wide  X 40’(12.0 m) high, our hydraulic door is being retrofitted in everything from commercial aviation facilities and private airplane and helicopter hangars to barns, agricultural centers, sheds and machine shops.

 

Remember, if it doesn’t come from Hydroswing,

it’s not a Hydroswing.

 

 

 

An Obsolete Hangar Door Doesn’t Mean an Obsolete Hangar

15. November 2014 14:25 by Hydroswing in Aviation , Hangar Doors

In many instances the useful service life of a hangar is defined by the economic viability of replacing a malfunctioning or out-of-date bifold or roller door. Today in aviation, the value proposition is extremely important when balancing the choice of a new build or the retrofit of an older structure. The frame of the hangar may live for many years, so there’s no reason the hangar door can’t produce the same structural stability and longevity. The addition of a new Hydroswing hydraulic door transforms your hangar and extends the life of your building.

Failed bifold is being cut up getting ready for a new Hydroswing door

Hydroswing is constantly bringing new life to perfectly good but aged, airfield and privately owned hangars. By removing the old and obsolete rolling sectionals or a potentially dangerous bifold door and replacing it with the simple, pre hung single panel Hydroswing® hangar door, the hangar is revitalized at a fraction of the cost of a new build. With no impact to the existing building structure, easy installation (usually only one day), very low maintenance costs, increased overhead space and  70% fewer moving parts than most aircraft hangar doors, Hydroswing is quickly becoming the number one replacement door in the world.

Delivered hung in its own frame the Hydroswing® hydraulic door is easy to retro fit or install in a new build.


Dust is a constant enemy to systems in aviation and industry. Old and outdated doors that have issues with sealing correctly causing a negative impact on the hangar as whole. Retrofitting an existing structure with the modern, sophisticated and almost 100% sealable Hydroswing® dramatically reduces dust content, allowing aircraft owners, MRO and service center operations to update ailing hangars. The Hydroswing creates a well-sealed and protected aircraft space, especially in desert or high wind borne debris environments.

 

You won’t lose head room either, the Hydroswing door is extremely space efficient!

Hangars are large spaces to heat or cool and temperature loss via existing damaged or aged bifold sections are inefficiencies that can be addressed simply by replacing the door. In addition, Hydroswing can easily clad or treat the new hydraulic door with exactly the same thermal properties as the rest of your building, especially important when calculating cost of ownership and in life ownership service costs of the overall structure.

Even when the building is replaced, the Hydroswing® can be unbolted and refitted to a new build easily with minimal effort. The Hydroswing® is truly, “restoration door hardware” for existing hangars. With a Hydroswing, your hangar is never obsolete. Don’t be defined by your old door, fit a Hydroswing® single panel hangar door to your facility today. Strong, secure, powerful, with minimal in life service costs and “touch of a button” ease of opening, the Hydroswing makes any hangar modern. When looking at the costs associated with hangar ownership, “re dooring” your existing hangar with a state-of-the-art hydraulic door may be the best option. Hydroswing is the original and still best hydraulic hangar door on the market.

Hydroswing for Quonset Buildings – There’s Nothing We Can’t Do!

4. November 2014 10:16 by Hydroswing in Agriculture, Architectural Doors, Farm Doors

The history of the Quonset hut (or Quonset “building”) dates back to World War l. In 1941, the US Navy was in need of an all-purpose, lightweight building that could be shipped anywhere and assembled without skilled labor. The Quonset hut was modeled after the Nissen hut which had previously been designed by the British. The name “Quonset” comes from the site of where the hut was first manufactured, Quonset Point, at the (now closed) Davisville Naval Construction Battalion Center in Davisville, Rhode Island.

 

The Quonset is usually constructed with corrugated galvanized steel. This lightweight prefabricated structure became a mainstay in war time for its strong demeanor and quick assembly. Between 150,000 and 170,000 Quonset huts were manufactured during World War II, with the surplus being sold to the public. The most common design created a standard size of 20 ft. × 48 ft. (6 m × 15 m) with 10 ft. (3 m) radius, allowing 720 square feet (67 m²) of usable floor space, with optional four-foot (1.2 m) overhangs at each end for protection of entrances from the weather. Other sizes were developed, including 20 ft. × 40 ft. (6 m × 12 m) and 40 ft. × 100 ft. (12 m × 30 m) warehouse models.

 

Over the years, the Quonset has been adapted for commercial use across a number of sectors. With flexible interior space possibilities, the natural fit has invariably been agriculture. These buildings are ideal for countless agricultural applications and Hydroswing® is the most effective door option for this kind of structure. Because of its unique shape, it’s important to have the exact door to accommodate the opening you need – on the side of the structure, or on either or both ends. Whether your Quonset is being used for additional storage space, or houses vital equipment, the Hydroswing® door allows for maximum headroom and the most efficient use of space.  Quonsets now come in a number of shapes and sizes and Hydroswing® can accommodate them all.

 

When considering a door for your Quonset, it’s important to know that a Hydroswing has no add on frames or needs no special structures. Our doors are pre hung, preassembled and ready to install. When fitted to your existing Quonset, the Hydroswing® single panel hydraulic door adds strength and functionality that can’t be accomplished with a bifold or roller door. In addition to Quonsets, the Hydroswing® can be fitted to steel, wood, tensile and concrete structures with little or no alteration to existing door size. In the event you choose to build new or replace the Quonset, just  unbolt the Hydroswing® and simply refit your Hydroswing® to your new building, (or Hydroswing® can do this for you.)


 There’s only one choice… it’s a Hydroswing®.

 

ISO 9001/ AWS D1.1 – Because Quality Matters

Hydroswing® is synonymous with quality. From the beginning, our standards have been the highest in the industry.  All Hydroswing® doors are fabricated in ISO 9001 facilities that adhere to the American Welding Society (AWS) D1.1 code requirements for welding of structural steel. Unlike other manufacturers, we understand the importance of working within specific codes and with vendors who boast an ISO certification. ISO (International Organization for Standardization) is the largest developer in the world of voluntary International Standards.  An independent and non-governmental membership organization at work in 165 countries, ISO began in London in 1946 with a goal to “facilitate the international coordination and unification of industrial standards.” Today, ISO has published over 19,500 International Standards covering almost all of manufacturing and technology.

 

 ISO 9001 is part of the ISO 9000 “family of quality management systems standards” designed to help manufacturers meet statutory and regulatory requirements related to a product.  A third party certification provides an “independent confirmation” that companies meet the requirements of ISO 9001. So what does the mean for Hydroswing® customers? It means we are confident in our selected vendors and we pass that quality to our end users.  The ISO 9001 facilities we work with have Quality Management Systems (QMS) in place and are stringently audited for welding and quality assurance. The hydraulic components are sourced centrally in the United States for further continuous quality and supply chain integrity.

 

At Hydroswing®, fabrication quality is just one area we set ourselves apart from others. Our welding is always to AWS D1.1 code which covers the requirements for “any type of welded structure made from the commonly used carbon and low-alloy constructional steels.”  Another example of our quality systems is our shot blasting pre-paint. This ensures the perfect base for the application of Carboline carboguard 890, a highly chemical-resistant epoxy mastic coating that adds 50% greater corrosion resistance than any other hydraulic door offered in this category. Shot blasting allows an added layer of inspection of the steel for rare imperfections which remain unseen in non shot blasted door systems.

 

 The quality control doesn't stop there!  Our patented Hydroswing® bow truss (US D584,831S) is unique in the industry and use only premium hydraulic lines, hoses and connectors. To make our standards complete, we also use only UL certified controls motors and pumps.  It’s all about quality. It’s Hydroswing.

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.

 

1998 the first Hydroswing door.


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. Don’t you want to be a part of our door revolution?

 

 

 

 

 

 

The Strength of a Hydroswing Hydraulic Door

Hurricane season is here. Hydroswing’s phone lines are lighting up as customers from severe weather zones begin to prepare. Customer after customer tells the tale of lesser doors on their own hangars and structures that turn to rubble, while neighbors with a Hydroswing® Door stood steady and strong. We’ve heard reports of bits and pieces of bifold doors on the ground at the end of the storm, while the Hydroswing® on the property remained virtually unaffected. 

 

 According to a report on risks of hurricane damage by Johns Hopkins University, “In a hurricane, gusts of wind can be expected to be 25% to 50% higher than the sustained wind velocity. Thus, a hurricane with sustained winds of 150 mph may produce gusts exceeding 200 mph. The effect of a storm's wind is best evaluated in terms of the pressure it exerts. Pressure varies with the square of the velocity, meaning that pressures increases very rapidly with increasing wind velocity. For example, a 100 mph wind exerts a pressure of about 40 pounds per square foot on a flat surface, while a 190 mph wind would exert a force of 122 pounds per square foot. As an example, in a 100 mph wind, a 4x8 sheet of plywood would be thrown by up to 1100 pounds of force.” 

Building owners need to be ready, and with a Hydroswing® you’ve got a better chance to protect your investments. Today, with budgets tight, it’s more important than ever to take every precaution to make your building structurally sound. Statistics prove approximately 80% of hurricane wind damage initiates with wind entry through the largest opening of a structure. This means that securing that opening greatly increases the chances of the survival of that structure – and the protection of its contents. According to the same study, “Garage door failure was a significant cause of damage during past hurricanes. The most common failure was deflection of the garage door from wind pressure until the tracks rotated and the door rollers separated from the tracks. Loss of doors resulted in envelope breach and a sudden increase in internal pressure.” This same theory will hold true for your hangar or warehouse door that is on rollers. With no rollers to consider, and single panel construction, the Hydroswing® is a must in hard weather and wind locations.

 After witnessing Hydroswing superiority (up to 200 MPH wind loading) for themselves, many weather-wary Gulf Coast residents are trading up to Hydroswing as well. If you’re an existing Hydroswing customer, you can rest easy knowing that when this severe weather season is over, you and your investments will remain safe and protected behind the sturdiest, most secure door system on the market... and if you’re not... make the move to replace now, or you may regret it later.

 

 

 

 

Introducing Hydraulic Doors for ISO Shipping Containers – A New Revolution in Hydraulics

ISO containers (also known as intermodal containers) are used to store and move materials and products efficiently and securely in the global containerized intermodal freight transport system. "Intermodal" indicates that the container can be moved from one mode of transport to another (from ship, to rail, to truck) without unloading and reloading the contents of the container. Lengths of containers vary from 8 to 56 feet (2.438 to 17.069 m) and heights from 8 feet (2.438 m) to 9 feet 6 inches (2.896 m). There are about 17 million intermodal containers in the world of varying types to suit different cargoes.

 

In recent years, ISO containers have started being used for countless applications outside of the shipping world. From architectural and commercial projects to mining and military facilities, a container that has “open sides” can make for endless usage possibilities. The fact that the Hydroswing® hydraulic door is pre hung in its very own load bearing frame, allowed the evolution and growing use of ISO shipping containers. Meet the ISO DOOR™ by Hydroswing®.  The Patent Pending system is built around our renowned single panel Hydroswing® hydraulic door. Sized accordingly, a hydraulic door can be fitted to the ISO shipping container on either of the sides, ends or top and can also be used for "cross-dooring" between containers for shelter buildings.  

The plug-and -play ISO DOOR™ simply locks on to side, ends (or links between sides or ends) of the ISO shipping container, utilizing the ISO tandemlok 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. With the same single panel strength the Hydroswing® Door offers, the ISO DOOR™ made a quantum leap into ISO containers.

The use of the ISO DOOR™ for UAV shelters, helicopter shelters, forward operating bases, checkpoints, encampments, military compounds, service areas, engine run up bays, MT service areas and many other modular ISO container shelter uses, can finally bring “closure" to the "open end" of the container shelter. Aviation facilities can quickly create shared wall, multi unit hangars at an affordable price. 

 Other industries interested in this unique door system are disaster relief, mining and exploration, specialized shelter manufacturers, special forces, oil tanker/vessel protection services and most obviously, shipping companies for ease of loading/unloading product into containers. The ISO DOOR™ system is undergoing review for full ISO certification so as to be able to enter the ISO shipping process and enable integration for containers fitted or modified to be shipped simply as a normal container… this is a logistical planners dream. 


Hydroswing® breaks the barriers once again…

 

 

 

 

The “Sustainable” Single Panel Hydraulic Door System

Sustainable means “pertaining to a system that maintains its own viability by using techniques that allow for continual reuse.” By replacing bifold or roller shutter doors with a Hydroswing® single panel agricultural door on your equipment and/or process buildings, you will probably never have to replace the door again. Hydroswing® is a sustainable solution to all your door needs.


The simplicity of a single panel hydraulic door compared to bifold and roller shutter doors changes face of agricultural buildings. With a Hydroswing®, (complete in its own frame, pre hung, ready to go “pillar to pillar” and right to the header), the wider you go, the better value it becomes. Safe and easy-to-use, the Hydroswing® provides almost zero in life service costs and therefore a guaranteed return on your investment. 

 

When farmers, ranchers and biomass producers consider the potential for door replacement in their older buildings, more and more they are turning to the single panel hydraulic door solution. With internal personnel doors, wind loadings to cope with forces of 200 MPH and strength to keep valuable machinery locked in and secure, the Hydroswing® offers the most attractive and cost effective source in the marketplace today. (Financing made easier than ever through our new equipment leasing program. ) For tractor security, plant and machinery security, Hydroswing® is the only choice for farm, biomass fuel, industrial and grain storage building doors.

 

 The difference is clear to see in the photo above, where one of three buildings has had two roller shutter doors replaced by one efficient, single panel hydraulic door. This addition adds door size, value, and in some instances, may allow you to use old buildings in ways previously not thought possible without constructing a new building. Concentrating on what you do with your building or shed is more important to your bottom line than replacing a door every two or three years.


The Hydroswing® will not pop out of its rails, rust away, flap in the wind, or allow pigeons or other birds in via the roller. With 70% less moving parts than a bifold, the Hydroswing® seals all the way round its own frame, and if required for food regulations, can be made 100% rodent proof. 

 Add value, size and efficiency by replacing your warn out or dangerous bifold or roller shutter doors to your biomass fuel store, grain store or agricultural buildings with a Hydroswing®. Sustain your door for years to come. Buy or lease a Hydroswing today.

 

 

 

Looking to Replace your Hangar Door?

15. July 2014 11:25 by Hydroswing in Farm Doors, Hangar Doors

Hydroswing® takes pride in meeting the needs of aircraft owners and facilities worldwide. Whether it’s new build hangars and the retrofit market, or replacing yesteryear’s aging number of unserviceable hangar doors, Hydroswing® brings the best to the marketplace.

The main issues facing airports and airfield owners, operators and tenants are the cost of hangar door replacement, return on investment, increase in door size, overall efficiency and the time it takes to install. The question Hydroswing® hears most is “do I have to replace my building or over build its door end structure?” The answer is NO. In most instances, you don’t have to scrap your building, just because your old door system is beyond economic service.

 


The Hydroswing® single panel hydraulic door easily replaces bifold, bottom rolling, concertina, stacking, barn, fabric, sectional/sliding and large roller shutter doors, in aviation facilities, private hangars, helicopter hangars and MRO facilities around the globe. There is minimal load and reaction levels to existing structures because Hydrowswing® is pre hung on in its own frame. This allows for a simple removal of old door and in many cases, no additional structural work. Our customers quickly see the benefits of “going big,” increasing the height to the eaves, and increasing the size of the hangar to the maximum of the building frame width or section.

 

If you’re in aviation, you’ve seen bad doors. Broken (and dangerous) bi-folds, torn fabric sliders, self-built disasters, and inefficient rollers and stackers can cost more than they’re worth to repair. Chains, pulleys, straps and too many parts can invariably lead to a break down and possibly an accident where someone may be injured or even killed. So isn’t it time for a change?

Cost effective, safe, and accommodating in sizes up to 150’(45.0 m) wide  X 40’(12.0 m) high, our hydraulic door is being retrofitted in commercial aviation facilities, private airplane and helicopter hangars alike. Simplicity, strength, ease of use and reduction in moving parts, plus use of cladding (which makes the door match the thermal characteristics of the building) are among the top reasons customers are making the switch to Hydroswing®. The sophistication of single panel hydraulic doors is now part of everyday door use across the aviation sector.

 

The original Hydroswing® hydraulic door is the ideal replacement for any kind of hangar door on any kind of structure. You can get the door you want now for ZERO DOWN. Call us today!
