Zendex RakJak operation and a look inside

- After seeing my video on the cheapest air jack you can buy, Zendex offered to send me one. Which I used then opened up.
It was so good I ordered another and paid for it with my own money.
They are available in the UK from Serenco.co.uk.
and Amazon - Rakjak 3 bag - amzn.to/2EmdX5K

Hockey pucks are great for adding to the saddle of the jack. Makes for a non marking/non slip lift.

"It doesn't go KERCHUNK like the Chinese one"
Then proceeds to show this one go KERCHUNK
I did say at the time it could have been smoother.
Would be nice if it rolled on a set of sprung casters that held it just over the ground until it starts to compress.
They make an L version with wheels & a long handle with inflate/release trigger.
Good review, I am totally convinced that I don't need one.
Keep up the good work thank you.
Lol right @700 each u could buy a cheap lift for 2k 4 of these would be 2800 now if u were only using 1…… well unless u wipe your ass with money $700 for a jack? If u can’t take 1 min of turning a bar to jack up your wheel u should give up’ not even logical’ it’s cool maybe for $100
Great video which confirms that I don't want one. I thought that they would be lighter than dragging a trolley jack on my gravel drive when working outside. I own a 3 ton Herkules air lift which is compact and very smooth in operation unlike you demo units. Thankyou
I opted for an ESCO 2 ton, just ordered it today, can't wait to get it :) yes sir, I will be doing a video of it.

you could have grinded a couple inches off the end of that allen key and stuck it in a drill to remove the bolts faster lol
Umm last time I was in Scotland, people still used miles. So yeah kind of the pot calling the kettle black there.
That’s a shame you paid so much, I’m selling 2 twin unitec’s - same company..
You could of saved a few quid.
What😮😮😮😮😮😮ohhhhh ok😅😅😅😅😅yeah uhhhh😅😅😅
Could use a remote uppy/downie switch...to avoid a random head-squashing accident.
They do make one like that, these ones are supposed to be used on your ramps. Mine were busy at the time but the floor was available. :)
I really don't like the fact that you have to get some of your body parts under or too close to the vehicle in order to operate it. Nuh-uh. I get that the truck has high ground clearance, but if it slams down, it could compress the suspension enough to give you a good smack. Plus if one of those bags ever blew out, the shrapnel could be nasty. All of that probably not the most likely scenarios, but it only takes one time. It would be safer with a remote valve to operate?
And that's why they make them with an extension handle as an option. :) But most of the time for me they'll be on the ramps and I'll be standing next to whatever I'm lifting.
@@DavidMcLuckie Good to know. I can see how using one of these with a long handle on a larger vehicle like a truck would be easier than a traditional hydraulic shop jack, where sometimes you don't have much swing to pump it up.
Feel like you should have used wheel chocks when you jacked up the hylux by the axle.
You're right.
Buy some ice hockey pucks, hard rubber and cheap
Drive up on the thing. Lift it high. Slide Jack stand under frame. . Let down fast. . Never have to get under truck. How bought that. . Huh!!! Aaa. At paccar tec center we would fill with water. For les julting of a seat ride. On test track., like sitting on a water balloon. Instead of air ballon. Differnt feel. Works on blow up dolls to. Lol for a more life like feel . Lol just joking but it would .
Great video... the first thing I noticed was how smooth the down motion is with this. What is the tallest jack of this sort that they make?
There’s really no justification to spend $900 on the RakJak compared to the $150-200 dollar price tag of the Vevor air Jack, the cheaper Vevor works just as good.
Great video, I’m definitely getting the cheaper (Vevor) version, a little sanding and polishing on the centre tube (and grease) would reduce friction and make the up & down motion much smoother, problem solved.
Reckon buy the cheap & "effective" air jack then sand, polish and grease the central pillar and with the $2000 savings, buy a barnfind classic! Win win!
No, I don't like how these air jacks make the cars jump.
Yeah, they do need to be used on a flat surface. Not ideal for all situations.
Your accent in this video was harder than the last one
That's because my brother was there.
If you had time you could Mabey take a bottle Jack. And if you could get rubber. To wrap. It. You could make your own easy. But getting rubber. Would be exspensive.
can't understand anything you are saying
Good to know
Hi from Oamaru New Zealand. On most jacks other that Railroad jacks when jack is too lowI prefer to jam a 5 x 5 or 6 x 6 block of wood between jack and chassis or load. On air jacks I like them to max at 70% of their max hieght limit.
Can u confirm if these use Firestone or Goodyear bags?.
Yeah the Chinese use a sintered bronze filter which are available from pneumatic industrial air equipment supply stores.
He sound like a drunk Dutch speaking English
Great when you watch a video all the way to the end and there's enough info there for me not to go and out and prime one, cheers dude for videos
hi , did you polish the telescopic sections on the chinese one? many thanks
I like your sound effects when describing the wonky lowering. Lol
I don’t see it worth spending $900 when a $150 one will do the exact same thing lol but to each their own
I've got a cheap jack too. It doesn't work anywhere near as nicely as the RakJak.
So it did exactly what the chinese one did, going up and down...
Yes, but without getting stuck.
David McLuckie ehh, it still looked a little wonky coming down. Either way, I’m buying it haha. So much faster to get up on jack stands lol. Appreciate the videos.
It was a little. But I've had to shake a car on the chinese one to get it to come down. Their beauty is the speed. Have fun and stay safe.
David McLuckie oh dear god that’s not good lol
@@DavidMcLuckie
their beauty is the speed so that you die a quick instead of a slow death when it fails.
Pritty expensive thou
They are yes.
There are some things you can cheap out on, and there are some things you shouldn't
Would cost the MFG less than a dollar to put a readily available baffle on that exhaust.
It needs a 6 foot remote to control it.
The Chinese jack lift my stateman nicely
May those lawnmowers you over there are different
if you dont like it. give it to me =)
nice video. thanks
what air compressor is required for using this ?
Depending on the weight of what you are lifting, but for maximum lift you'll need around a 100 psi.
How much u buy it for
it price
it raises quite violently compare to traditional jack
Depends how much you press the lever really.
Hydraulic is Fluid
Pneumatic is Air
good

Bulky , will not buy this
I'm curious how the physics work on your planet?
You know what, thank you for the video, but I think I'll just keep with my shitty $40 hydraulic jack or the scissor jack with jack stands. Those pneumatic systems don't seem safe.
Jacks only ever for lifting and lowering, always, always use jack stands to hold a vehicle.
Here's an idea, would that 3 bag air jack have enough lift to raise your vehicle service ramps ramps to the level position in one go, that would save a lot of time & effort; good review by the way.
There is a reason I didn't use it at the time. I can't remember exactly, but I think it was height related. But you've inspired me enough to go and look at it again and see if I can make it work. :)
I like the Chinese one for its handle and wheels but I would polish the telescope sections.
I think Zendex do air jacks with the handles on them. If I had a lathe I'd take the telescopic sections out and polish them as you say.
👍👍👍👍👍👍👍👍
They look good but they are out of my price range, More the price range of a garage. But great review.
Yes, they are priced for garages who will probably use them eight hours a day everyday and they'll have to survive. While I use mine often, they don't get the abuse a garage would give them.
@@DavidMcLuckie Like you say for a garage they are great, Have you done anything videos on Air bottle jack's ? They seam more in my price range. But keep up the good work your videos are good.
Stu
The air bottle jacks just use the air to actuate the lever for pumping the hydraulic part. Just puts them up faster than doing it manually. :)
Is great i work in that company i love make that product
I fucking love these. Use them practically every time I need to work on a car. They are great.
@@DavidMcLuckie yes my friend do you check the longe handle already
👍
how much pressure you need to inflate that jack? and what compressor you use?
Pressure required depends on weight of vehicle. I could lift a smart car as soon as the compressor started with no real pressure, but for something heavy it would take the full pressure of the compressor, which is my case is 120-150 psi.
Peter Go
It’s the CFM what pushes it no the PSi, more capacity your compressor in the CFM department the better things work, larger ID 3/8” airlines and fittings you’ll need to really run 3/8” BSP not your standard 1/4” BSP fittings ..
The longer the hoses more PSI at the compressor nozzle you’ll need, I run 160psi so the gun gets around 155psi but when in use it’ll drop to 90-100 psi which is within tolerances and specifications, most run 90psi at the nozzle and gun will receive 80-/+ 5psi then in use you’ll automatically lose around 40psi...
5five6 I think you’re a little confused. You can lose pressure by line loss if you have a small line with a large volume tool, but this jack is an air receiver that will ultimately equalize with the air receiver on your compressor. If you have a smaller long line from your compressor and need the pressure to be more stable, you can tee a tank (I’ve used a propane bottle) near where you’re using the tool, it’ll act as an accumulator.
Get a house Jack for 12 dollars
No need for cars. This, one needs a compressor. Means more money. For a couple of hundred dollars we can get an electric hydronic compressor. I own a compressor an don’t want to spend that much again but don’t want to spend an extra 300-500 dollars for those either.
Very annoying to watch!
The whole thing or any part in particular?
They are still scary to use i would never climb under that thing ill stick to my small floor jack they are great and there like 30 $$$ lol thanks for the cool video !
No. Never work under ANY jack. That's what stands are for.
