Our definition of engineering is the art of applying scientific and mathematical principles, experience, judgment, and common sense to make wheelchairs that meet the wants and needs of individuals. RGK engineering is the process of producing a very technical product to meet a specific need.

Engineering work is organized by traditional academic fields of study. The five largest of these are chemical, civil, electrical, industrial, and mechanical engineering. There are also more specialized engineering fields, including aerospace, ocean, nuclear, biomedical, and environmental engineering. In doing a search on engineering you will find that there are a growing number of engineering types like those involved in research, design, analysis, development, testing, and even in sales positions.

One RGK Advantage is with the number of wheelchair users involved in every aspect of the prescription, design, build, and set up of the product. RGK founders and product users, Russel Simms and Greg Eden have years of insight that compliment the work they do on each and every product that goes out the factory door.

Now, with the formation of RGK Wheelchairs, Inc., Reg McClellan a product user and individual entrepreneur who initially brought Quadra and Kuschall to the Canadian marketplace, lends his 30 plus years of experience to the North American market.

We use the intelligent choice when it comes to designing your wheelchair. ParaCAD+ is a powerful 2D Computer Aided Design system, simple to use but having the major benefits of interactive parametrics, tailor ability, high-level programming language and functionality found only in CAD software. ParaCAD+ uses a standard user interface associated with the Windows environment. As you would expect from Windows based software, paraCAD+ allows the user to edit multiple drawings simultaneously and to cut and paste between them. Therefore, within paraCAD+, several drawings can be opened at the same time allowing information to be obtained from one drawing and used in another. This makes it easier for you and us when you tell us you like the sizing on a particular RGK wheelchair (note the serial number) but, you would like to extend the frame by 1mm, shorten the back by 2 mm, etc.

Our paraCAD + system is especially designed for productivity related to making RGK wheelchairs. ParaCAD+ has an intelligence not available in other systems, which understands drawing units, sheet sizes and drawing scale, and allows us to modify these at any time during the design process automatically updating the drawing. This intelligence also offers the designer many benefits and time saving features, such as: being able to toggle between units when entering values for distances and angles; symbols drawn in one type of drawing units (e.g. inches) are automatically scaled correctly when inserted into drawings set to other units (e.g. mm); dimensioning on a drawing can be automatically converted between drawing units simply with the selection of one menu item.

In concert with our philosophy of "always pushing to be better, faster, stronger" we are making a transition to software programming that will enable us to view and produce three dimensional imagery along with a host of other industry complementing improvements.

We take pride in our ability to engineer a product that is going to meet and exceed the customers expectations. In order to do that we are constantly researching materials in the marketplace that are going to give us an advantage in the production of a better means of getting you from A to B.

Titanium is a material that we use because it has excellent corrosion resistance properties and superior strength-to-weight ratios. It was discovered in 1887 and dramatically refined in 1910, but it really became popular in the 1950's as structural material for the aircraft industry. Titanium is the fourth most abundant metallic element found on the earths crust in North America, South America, Europe, Africa, China, Australia, Russia, and many other countries. Contrary to popular belief, welding titanium is not difficult. It requires a very clean environment free of reactive gases and a TIG process (Tungsten Electrode Inert Gas) using Argon gas shielding. We use 3-2.5 because it has 30-40% improved strength over commercially pure grades and excellent corrosion resistance, form ability and weld ability. It is commonly available from both distributors and mill sources. Beta Transus (F +/-25) 1715. In the cold worked, stress relieved condition, 3-2.5 tube product can obtain tensile up to 125,000, yield up to 105,000 and elongation up to 15%.
