Bendpak RJ-45 question

[DerStig]

Does anyone know:

- How many safety locks does it have - another website says 3 but i m not sure if ifs right
- Whats the lowest and hightest lock positions (or the other lock positions)

Surprisingly doesnt mention in bendpak website. I can call them but usually their sales people can only tell whats on the PDF files.

 

[LX-Markham]

3 locks
and i would have to measure the lift height

Thank you is there anyway to measure if its not too much to ask. I really appreciate it

 

[LX-Markham]

based on the ceiling height guestimate thread ....some people might be able to provide an answer based on the following pic LOL

 

[DerStig]

Its tough to make out the height from that picture

I'm pretty sure I wont be able to use the 3rd lock. Just curious how much 1st and 2nd will get me.

 

[LXCam]

I want to say it's right at 12". I know it's more then 10" because of some body jigs I made and it'll lift over the alignment pins for those but not much higher.

 

[LXCam]

Alright dude you owe me one. Just for you I fired off the compressor and lowered my lift so I could get the measurements just to make you happy. So these measurements are with just the single pad on the arms from the ramp surface. 2.5 at rest and the other measurements are set on the locks. Full rise is maybe 1/2" above the 3rd safety

2.5 / 8 / 10.5 / 13


I'll be expecting my case of Dom Perignon next week right

 

[DerStig]

I really appreciate it. It means a lot to me. Thank you very much. DP is a bit too much, but I'd be happy to buy you a 6 pack of your choice and pizza Thanks again I m grateful.

That works too, I'm not picky. But it never hurts to ask right?

 

[DerStig]

That unit is super cool by the way. Do you see any issues with using it while the 4 post is fully lowered? Do you need to get under the car to access the safety locks to lower it?

Also, whats the advantage of the air line? I watched the videos but i didnt understand.

I can tell you it's not easy to use when the lift is on the ground. But that really depends upon what it is you're working on. There's a huge difference between say having a challenger on board verses a full size truck. Also you can have it facing whatever direction you want. So if you really needed to get to the safety lever you may need to turn it around.

As for the air hose I don't know what you're referring too?. You need air to operate the jack, I just use my standard air lines.

You might be able to reach the lock, but accessing the foot pedal to lower the jack might be a challenge. It's right in the middle. And you'd be lowering the car on your head.
Moving the jack also wouldn't be easy. It rolls, but it takes some effort. ***** is heavy.

Brings up my one pet peeve of this bridge jack: why did Bendpak use a control unit that has a foot operated pedal on it? It would literally be impossible to ever use the unit with your foot.

I had to order a replacement "foot pedal" for my RJ-45 because I caught it on my suspension while driving off the lift and broke it in half. When I called the customer service rep, I referenced it as the foot pedal. The rep laughed and said "yeah, everyone calls it a foot pedal because of the way it looks. No one could ever you their foot to operate it under normal use conditions".

I dont understand sorry are you saying i have to use my foot to release the safety locks?

 

[LXCam]

No it's just the style of device that operates the jack. It's a combo foot petal and fluid tank which is why they probably went that direction. It just saved additional plumbing verses a separate tank and actuator. Don't put much worry into this, it's all operated by hand just fine......or by a stick if it's on the ground

Wish I had bought a second RJ-45 when I got my 14,000 lb. BP. There have been so many times I needed all 4 wheels up at the same time. And yes, I am not a fan of 2 post lifts.

I have only one but modded this receiver to fit as sliding jack platform for bottle jacks or jack stands. I can have all four tires in air for removal and do anything needed

 

[DerStig]

Thanks for responses.

How do you flip the unit, as in if one side is not resting on the rails of the runway, is that stable? Sorry cannot picture in my head as to how it turns.

 

[LX-Markham]

huh?

It doesn't flip or turn.

It's made of white metal and is quite brittle.

As for why they chose a "foot pedal": I understand they used an "off the shelf" component, but it just seems weird. It works okay, but I think there would be a much better, more appropriate style of lever.

 

[DerStig]

Sorry I reread the message that was posted about facing it either direction, I misunderstood what was said. All good now. Thanks for the help

 

[DerStig]

Hang on, I was reading the manual and this thing requires a constant 20CFM@100psi? Isnt that a lot and would require a professional compressor?

The hd9 lift itself only needs 3CFM@30psi

I have california air tools model 4620ac which has 125psi but at 90psi it has only 5.30CFM.

Am I reading this right or do you really need a $1500 compressor with 5hp to use this jack

 

[LX-Markham]

As long as your air tank is big enough to supply 20 cfm for a short period of time, you should be fine. It's not like you need 20 cfm constant supply from the compressor. It only takes a few seconds to lift to full height.

But it does use a fair amount of air. My compressor often kicks in after a couple of lifts. The HD9 only requires a tiny amount of air in comparison because it's only for the 4 small air cylinders that operate the locks.

 

[DerStig]

Yeah I dont know if this will work I have an "ultra quiet" compressor running only at 68db and its 4.6 gallons. Is 4.6 going to be enough?

Last thing I want is a 90db big *** compressor in my garage

Why doesnt this thing work with just hydraulic fluid

 

[LX-Markham]

You could look at the Direct Lift Pro Jack 4500 instead. It's way cheaper and doesn't require air.

somebody chime in whether or not it would fit the Bendpak rails?

That compressor will work just fine. It won't be as fast as a larger unit but big deal.

And when a said I said you can turn it maybe what should have said is you can have it facing either direction, 180 degrees. I occasionally rotate mine depending upon what I need access to in relation to my jack points. But at 300lbs I use my hydraulic table to set it down on, lower the lift, spin it and back on she goes.


That other jack if you could provide the measurements of the guides I can check my rails for fitment. I'd wish I had bought two also, but I make due with other means when I need everything up in the air.

 

[DerStig]

Understood thanks.

Also it says maximum arm reach is 59". I'm guessing that means this wont reach to pinch welds or lifting points of pretty much any mid size sedan. Standard 5 series BMW is around 70-75" side to side. Corvette Z06 is probably even wider. So how would you position this to do any suspension work where the standard control arm or K member cannot be stationary.

Or is 59" for one side only measured from the center? Its not really clear. If its the distance between two edges of the arms when they are extended then its really short no?

It's 59" at full extension outside to outside. I don't lift on the pitch welds and there's plenty of suitable locations for jack points if you use a little common sense . I've had a pretty insane assortment of rides on my lift and can't remember ever having an issue.

 

[LX-Markham]

I guess I have dealt with too much old junk in my time. I would never lift a vehicle from the pinch welds. Good chance of the jack punching right through the rot, LOL.

here is a pic of mine when I was replacing the front control arms on my Mustang. I had the bridge jack positioned under the front k-member.

Direct Lift: rolling jack will work

 

[joel]

... It rolls, but it takes some effort. ***** is heavy.

....

My RJ45 jacks were tough to roll also.

Turns out maybe 2 years ago Bendpak changed to ball bearing rollers.

I replaced the rollers with the new design (simple swap) and the jacks are WAAY easier to move.

 

[LX-Markham]

The rollers on mine were slathered in paint from the factory. I had to take them apart and clean off all the paint to free them up. Jack rolls reasonably well now, but it still takes a bit of a shove to get the momentum rolling, LOL.

 

[DerStig]

Regarding the compressor, the heaviest of my cars weigh 4500 lbs. The jack would be lifting 2250 lbs.

With that in mind, does it make sense for me to upgrade my compressor to a 15 galon unit? I think from a CFM and psi perspective, my current compressor and the next model are identical. However mine is 4.6 gal the other one is 15 gal. I am asking this because I am actually in the middle of resolving shipping damage with the seller of the compressor. He offered me full refund if I want so I can return it get my money and pay extra for the other one.

The links for the compressors:

Current: http://www.californiaairtools.com/u...ompressors/2-0-hp-air-compressors/cat-4620ac/

Proposed: http://www.californiaairtools.com/u...ompressors/2-0-hp-air-compressors/cat-10020c/

OR

Proposed: http://www.californiaairtools.com/u...ompressors/2-0-hp-air-compressors/cat-15020c/

The one I have is $280, the 10 gal one is $360 and 15 gal is $394

I am just not sure if bigger units will be beneficial. If they will make a significant difference, I am happy to pay more and swap.

 

[DerStig]

Are you sure Direct Lift Pro Jack 4500 will fit to HD-9?

Bigger is better!

Actually, my compressor is a bit small...so I raise the RJ45 jacks in a few stages allowing the tank to refill in between. So it takes me a bit longer. Works fine.

What are the specs of your compressor?

 

[DerStig]

Also, I'm most likely going to go with Rj-6 instead due to the 64" reach. My bmw is 62.5" between jack points and I went under the car and the entire car is pretty much covered and there is no way to know where else I can lift without removing all the underbody panels. I remember my friend's 997 having similar problem so maybe euro cars may be pita to lift anywhere but jack points. 59" of reach is really not much and probably wouldnt cover cars like z06 (and probably more cars in the future as they get wider).

Its only $100 more when you consider how much I am spending for everything, its not much.

 

[DerStig]

Bump

I'll check for you. It may take a day or so.
