Wheelchair Testing Information & Videos

The "Center of Gravity Test", or  “Wheelchair Stability Test”. This design and engineering test measures both adult or pediatric wheelchairs for stability. The Centyer Of Gravity  test uses a mechanical tilting platform to determine the center of gravity of a fully loaded wheelchair with the brakes applied. By identifying the wheelchairs center of gravity, we can design a well balanced / steady and safe lightweight wheelchair. The precision tilt machine is also used as a research and development tool - it is used to determine wheel spacing and tilt angles so that we can manufacture the safest and strongest wheelchairs possible. The Stability Test conforms to guidelines set by The American National Standard Institute.

The Accelerated Fatigue "Wheelchair Strength Test", also  known as the "Bumpy Road Test", is our most severe wheelchair durability test. This rigorous test simulates the harshest conditions to ensure longevity and durability. Using a twin drum device, we subject a fully loaded lightweight wheelchair to a grueling 100 hours of simulated bumpy road strain. One hundred hours is TWICE the National Standard and gives Convaid the confidence to offer a lifetime warranty on our lightweight wheelchairs

The "Wheelchair Stress Test", or wrack test  The Wheelchair Stress Test machine grabs the wheels on the wheelchair, and twists the frame back and forth. After 10,000 cycles at 8-degrees deflection, all Convaid wheelchairs tested still tracked straight. We are the only wheelchair manufacturer that subjects our mobility aids wheelchair products to this of test. Many of our  Convaid folding portable wheelchairs use a “spring loaded” frame design that allows for the frame to flex when going over bumps or uneven surfaces, this provides a natural shock absorption.

It is our objective to make Convaid lightweight compact folding wheelchairs  as easy to understand as possible! We have available an array of informational  and instructional wheelchair videos for you to watch and to learn from. You can also visit our Youtube Convaid Wheelchairs Video page.
