In 1990 I designed this wheel with suspension and damping incorporated.I am glad to see this on the market. In those years I had no luck finding some business to develop and sell it. cruzraylson on May 5th, 2019 - 9:19pm

Loopwheels fit most manual wheelchairs using standard quick release axles. Choose between 24″ and 25″ diameter wheels, with or without Schwalbe Marathon Plus pneumatic tyres. These wheels have a standard axle bearing diameter of ½” (12.7mm). If you need a 12mm axle bearing instead of ½” then please contact us.
Both modeling and experimental results demonstrate several realistic scenarios in which wheel hubs experience accelerations greater than 100g, sometimes at very low vehicle speeds. This paper focuses on the experimental determination of suitable design goals for in-hub motors (wheel motors), describing the experimental test rig, experiment procedures, and experimental results from testing conducted at UT-CEM. The paper also discusses implications of these results on wheel motor design, leading to the conclusion that a realizable and feasible design goal for a combat vehicle wheel motor shock rating is 150 g's, with a 10 to 20 ms pulse width.
I find it difficult to credit the coach moving down the hill with 20,000 - 40,000 lbs of motorhome pressing the jack pads into the earth. That assumes the jacks are rated for the full coach weight and don't break under the load. My 36,000 lb coach had 4 x 16,000 lb jacks, so I wasn't too worried. Back in the day some coaches had poor frame rigidity, especially up front, so the front cap and windshield frame would often twist if the front wheels came off the ground. My '96 Southwind (F53 chassis) was like that and I avoided ever lifting the front to even barely touching cause the windshield would start to move. My 2002 W22 chassis coach didn't seem to have any problem with that but I was still careful. My 2004 DP was stable as a mountain no matter how much it was jacked. Spent many a summer at my brothers home in SW PA with wheels off the ground. He lives on a hill side and the 2012 Tour never had a problem.
And it's not like I have some high dollar customer sport chair, either. I use a "Breezy". Street price of $575. About as cheap as you an go. (https://www.quickie-wheelchairs.com/Breezy-Wheelchairs/Breezy-Lightweight-Wheelchairs/Breezy-600-Lightweight-Wheelchair/2403p) And the only modification I made was to cut grooves into the solid rubber tires. (They come smooth as a babies butt. That REALLY doesn't work in snow.) Grunchy January 31, 2018 01:30 AM Reason January 31, 2018 05:28 AM
Loopwheels are designed, engineered and made in Nottinghamshire by Jelly Products Ltd. It’s a registered design with patents pending.
Stable PU wheel design gives the kick scooter both added stability and safety. No need for a kick stand or for unbalanced riding.
The most loop-the-loops in a Hot Wheels track is 10 and was achieved by Rohan Dayal and Rahul Dayal (both India) in Mumbai, Maharashtra, India, on 7 April 2021. It took Rohan and Rahul three days to build the adjustable angle wooden platform and assemble the entire track of 10 loops over it. Two people were involved in the project. Rohan Dayal and his younger brother Rahul Dayal. "Testing was initially with few loops and as we increased the loops and the length of the track, the project became challenging. Since the track became long it needed to be supported on a firmer wooden platform. The longer the platform, the greater was the weight and bending in the center. This needed strengthening of the platform. This was the initial challenge." While testing the brothers found that the journey of the car through the loops depended greatly on the angle of the platform. To facilitate variable angles they had to construct an adjustable wooden leg support. By adjusting the leg support during testing they arrived at the best angle which gave them the breakthrough that they could achieve the target. The project cost approximately INR 3500 ( approximately £35). The cost was less as the brothers already had collections of Hot Wheels cars and track and only had to purchase the remaining missing track pieces. The plywood used for the platform was upcycled from scrap. There were a numbe rof challenges faced by the pair. As the number of loops increase, the project became challenging in terms of scale. The length of the platform, it's weight, and height also presented difficulties in handling. The speed of the Hot Wheels car increases as it descends from greater heights causing the car to lose balance. Despite all these difficulties the pair think they could attempt to increase the loops by a further one or two in the future. "Since a young age of around 12 years, I would try to do small projects like making a wooden toy car or cricket bat. Later as I grew I would do some small household repair works. For all this, I would use my Dad’s tools. As a child, I liked playing with toy cars. I would make my wooden toy car and make it slide on sloping surfaces. During this time I was gifted with Hot Wheels cars and tracks which came with super smooth cars and steep sloping tracks. Soon I had a good collection of it. Recently I came to know about the Guinness World Record of 8 loops and decided that I can better the record. The Guinness World Records titleholder would be the best thing I would have ever got. It would also mean that records are an inspiration to do better and create greater records. It would be a proud moment for both me and my family."

You realise in the mining truck example if their estimate of current tyre prices is out by a factor of nearly 3 (as you suggest 38k v 110k) then the whole financial justification falls apart ;) Harmen van Kamp February 2, 2018 12:30 PM
