Air Bag Jack

[Tony H]

I was looking at shop tools and came across some air bag jacks. Probably an old idea-I just never noticed it. Seems like a good idea. Anyone used one? Obviously I would not get under a vehicle supported by one.

Never used one or seen one in person.

I am not sure if this is the same thing but I saw it on TV back in the 1980's. It is a big sturdy bag and you shove it under your car and stick the hose on the exhaust pipe it the exhaust pressure fills the bag and lifts your car. But on TV is the only time I have ever seen one.

It sounded to me like something handy for off road vehicles could if they were stuck or the ground was too soft for a normal jack. But seemed too unsteady for the normal jacking of a vehicle.

This is a shop tool using compressed air. 6600lb cap. Here's an example:

Thanks I would like to see it. The computer I am on now has dial up internet and the site will not open up fast enough for my patience. I will have to try tomorrow on my other computer.

Wow-dial up. The ads must take up a lot of your time. I have never lived anywhere with really fast internet. But it has always been small, rural towns. Maybe I can post a pic of the jack.

Well I was at a friends House and used the WiFi and saw it. Now I am back on dial up and I see someone posted some pictures of it.

Just from the pics the diameter of the apparatus will limit where it can go/fit into.

I am guessing it is a lot faster and there could be some height advantage.

Clearly you sometimes need a jack under someplace where there is not going to be room to use a Floor Jack due to the need to move the handle up and down.

But, I think they have air powered jacks that look like a Hydraulic Jack. I don't know if those would go has high but the ram on a hydraulic jack is smaller in diameter so it can gain purchase on smaller places.

This is supposed to be advantages of an airbag jack.

The air bag jack Advantages(from yaqiya):

1. Easy and labor-saving: with the use of pneumatic automatic lifting, no manpower, easy and free

2. Convenient and quick: the lift is very fast, the general car only needs about 3 seconds to rise, and the advantage of ultra-low chassis is highlighted

3. Do not hurt the chassis: as the contact part with the body is imported soft rubber, the top of the car bottom can be increased, and do not hurt the chassis

4. High cost performance: due to the long service life, although the price is high, it still has a high cost performance.Such as: ordinary horizontal top 300 yuan can be used for half a year, 5 years with 10 300 yuan is 3000 yuan, pneumatic top 1000 yuan can be used for 5 years.

5. Rugged and durable: the airbag exceeding the national test standard of 24 mpa can be used up to 100,000 times, with an average of 50 times a day, which can be used within 5 years.

6. Free maintenance: because it is a pure pneumatic product, without hydraulic oil, no oil leakage phenomenon, do not need to replace the sealing ring, more because the air bag itself is a rubber product, the port is like a sealing ring, gas sealing is very easy to complete.

7. Improve store image: the use of this product is conducive to attracting customers and improving store image.

8. Use: at low temperature by using high-performance gasbag, under the condition of to 40 ℃, the performance is also excellent.

9. Wide range of use: due to the plane contact with the ground, it can be used as usual in the sand and snow, without subsidence and failure to support.

I don't know on this one. I think you will still need your other types of jacks.
There is a small Tire Shop near my place and they have one Car lift and when they are doing more then one Car they use Jacks. That place could benefit from having the Bagjacks because it would be faster and they apparently don't need to be a picky where the jack goes under the Car.

I have had cases where the typical floor jack was under the Car and I only had room to move the handle up and down like 3-4 inches. Very tedious and the Jack takes up a lot of room under the Car.
Typical bottle type hydraulic jacks don't have the same height/liftt as a floor jack does and putting wood blocks or bricks under them is not the best thing.

Obviously not everyone has an air compressor and air compressors sometimes fail and it can be something small but critical like the overpressure valve going bad.

There seems to be a clear advantage in height/lift. But when deflated I think a floor jack will slide under things that are 4-6 inches off of the ground. The Airbag jack looks like it need more height to get it under something.

If you had a busy auto repair shop there is times it frequently be handy to have and if it saved time that would eventually pay for it.

But, home it would could be a convenience but not something you would absolutely need except for special circumstances.

If you are a person that has a lot of cars 2 of them would be handy when it comes time to rotate Tires on all of your Cars. With a bit of hustle and an impact wrench you could do say 4 cars with in and hour with less trouble then with other jacks.

I guess there are situations it would be useful. Just depends on the job. 2 of them would be nice. I'm sure the shops use whatever works the best for them. I would wonder about stability when fully extended. A floor jack offers some stability but I would not depend on it.

Ya, you are not supposed to depend on any Jack. You lift and they you support with something better and safer.

My Father had a US made floor jack that used to slowly leak down. It was time consuming to get it into the little fill hole but I filled it with 90 wt differential oil. With that in it took a really long time to leak down.

My dad had a car almost fall on him when the floor jack went over the top and folded up backwards. Last time he used a cheap, parts store jack. I am ultra conservative with safety. the older I get the more so.
