Personally I don't like to lift wheels off the ground with the jacks and I would never lift the drives off the ground. If it's so unlevel that the wheels would be off the ground, I'll run up on some boards first to get close, then finish leveling with the jacks. Fronts are ok. You won’t damage anything. As stated above, never the rears (drive wheels) because the parking brakes are on the rears. If you’re not comfortable with the fronts being off the ground, you can build some small ramps or wood blocks you can drive the front wheels onto. If you search for ramps on this forum you’ll find lots of examples. When an air bag RV is lifted, ONLY the axle weight is left on the ground. no matter the lift height. This is unlike a leaf or coil spring vehicle. The tires provide limited stopping. If the leveler pads are on softer ground, they will put much restriction to the RV moving sideways as the pads will be in a hole. The suspension system has no problem handing from the shocks / limit straps. It endures FAR greater stress while you are driving down the road soaking up the bumps and road heaves. All that being said, try to NOT lift the RV any further up than is required. Things inevitably break. Hydraulic lines, solenoids, seals etc. You don't want a single leg to drop on it's own which the torques the chassis. An RV up in the air is invitation to crawl underneath or store stuff under. Not good when something breaks. So, pick a more level spot or use blocks to get the rig as level as you can before lifting. Don't park on a hill and lift so that there is no chance of slipping sideways (tire and / or leveling pad friction). Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times... I don't like to lift either off the ground ever. I only use the jacks enough to level the final little bit and to not have the coach shake while moving around in it. The thread Sonic posted is great! I use 2x10s like suggested in the posted link, but took it slightly further. I didn't cut an angle, don't really need it and in the past I found that it sometimes gives them the ability to slip while driving onto them. I would post pictures but it is in the shop for engine repair and the boards are in unit. Basically I took 2x10s and cut 2 boards the longest that would fit in the bay I was storing them in (about 36 inches long). I then cut 3 more boards about 8 inches shorter (for a total of 4 boards high), so lenghts of, 12, 20, 28, 36 long. I have 2 sets in case there is a need for the rear duals to go on boards. To keep the boards from sliding when driving onto them, I bought 3 different size carriage bolts that would go through 2, 3, or 4 boards but not all the way through, just long enough to keep them stable as you drive. I then took a spade bit that was 1/8 inch larger than the bolts and drilled through all 4 boards to accommodate the bolts, i did this in the rear where they would line up even and no worry about puncturing tires if they popped up slightly. I then took a spade bit slightly larger than the bolt head, and drilled on top of the holes the thickness of the bolt head. This way they sit down flush with the boards. It works very well! For the jack pads, I couldn't use anything very thick, as if I am on level ground and I dump the air, I only have about 4 inches between the jack pad and ground. I took 2x4s, and cut them the length of 3 2x4s put next to each other. I cut 6 in total. I then laid them crossways (think the first 2 layers of Jenga) and nailed them together from both sides. These work great for leveling! When i get it back from the shop next week I will try to remember to post some pictures. Your drive axle (brakes) always have to be on the ground... else you'll go down hill as soon after you've walked bow to stern inside the coach a few times...

Innovative design means the wheel has a stiff structure but an element of compression. The springs within the wheel are made of a carbon composite material. .

ko2's are more like 1k. unless he puts on some P rated stock size ones. which seems silly. $800 on Amazon for C load 285's - so I was a little off. I was also assuming prices of shopping around, or else the SPC's would've been stated a bit higher. Reply With Quote 03-15-2020, 11:03 PM #5
While entirely theoretical, Lee’s design is not without merit. Spokes and rims found on any standard bicycle already absorb shock, albeit minimally.

I don’t see how they could maintain torsional stiffness under braking… And that falls into the “bad” category. Mindless on April 15th, 2013 - 12:58am Gillis on April 15th, 2013 - 1:41am

    How is that ? Do the jacks being driven into the ground by the weight of the chassis slide ? Does your table, grill, chairs, slide down the site ? Do you have brakes in them ? I did rear brake jobs on large trucks, when I jacked them up, they stayed right where I parked them.
    As a full time wheelchair user, I cast a very skeptical eye at said "annoyingly infomercial-style video". About the only places I have trouble are in soft gravel, sandy beaches, and deep snow. Certainly not gentle curbs and flat lawns.

    You’ll notice your loopwheel has more movement, vertically and laterally. As soon as the springs are loaded, they compress and further change their concentricity. This is what gives your wheelchair comfort and shock absorption. A Loopwheel is designed to absorb shocks, reduce jolting and cushion your body against vibration. You’ll notice more sideways movement than with a spoked wheel, but you’re trading rigidity for greater comfort.

    'I've now been working on making it a product for 4 years, and we've made 40 wheels and 200 springs to get it right.

    “In the past, if I wanted to go down the sidewalk or over any big bump in a regular wheelchair, I’d feel it a lot on my back, and it would really hurt. You do it a couple of times a day each day, a week, a month, a year – you’re talking about thousands of times,” Cohen told From the Grapevine. “With Acrobat, it's all absorbed into the wheel and not in the back, creating a better sensation when riding a wheelchair.”

In addition to any of the points mentioned above, it is recommended that you (or your mechanic) visually inspect your steering and suspension systems if you notice any of the following symptoms:

With standard quick release axles, a choice between 12mm or ½ inch bearings and available in 24″ and 25″ sizes, Loopwheels fit most manual wheelchairs.

Jelly Wheels

Why reinvent the wheel? Because sometimes it makes for a better bike. Loopwheels are a completely new type of bicycle wheel, designed with a unique built-in suspension that makes for a delightfully smooth ride. Instead of spokes, as on a traditional bicycle wheel, the Loopwheels have three loop-shaped springs that allow the wheel to absorb the vibrations and bumps most riders are accustomed to feeling.

Loopwheels come in front- and rear-specific versions, one of the key differences being that the springs in the front wheel are twice as compliant as those in the back. This is (presumably) to help keep the wheel that does the steering from being knocked and bounced around, plus it compensates for the fact that more of the rider’s weight tends to be centered over the rear wheel.
