Bendpak RJ-45 rolling bridge jack

[J Persons]

Anyone with this bridge jack? I'm considering it, but the requirements for the air is 125 PSI and 10 - 20 CFM. My compressor is a single stage 60 gal and has 115 PSI and 10CFM. Will this jack work, even minimally, until I can upgrade the compressor to a two stage to get the required CFM and pressure?

You will be fine with your compressor. I have a 60 gallon Quincy with that jack and have had no problems. It may require 10-20 CFM but only for short times and the reserve in your tank will handle that.

My compressor is half the size and no problems here.

Agreed with these guys, I have the same jack and it does not take much air at all. Your compressor will operate it no problem.

The rolling jack doesn't use much air at all. Once you have it in place, you will wonder how you got away without it in the past. Best investment you will ever make except for the lift itself.

I also have that rolling jack and no issues at all , like someone said it does not take much to get it to go up.

I think everyone covered the air requirements question, but my recommendation is to consider buying 2. Gives the benefits of a 4 poster with most of the benefits of a 2 post lift.

The price for two of the rj's almost gets you to the price of another lift. I like the idea, but is not very cost effective.

I use a stack of 2" x 8" pieces of wood in place of jack stands, under the frame rails to be able to move the rolling jack to the other end of the car, once I have the section that I am working on off the runways. I have never found anything that I couldn't do using a little bit of Yankee ingenuity with one jack.

Have that jack with small 60gallon. Works great!!! Love it

I have one jack and have been thinking about getting a second. My main complaint is when the jack is in the rear the control switch is forward or under the middle of the car. If your just doing tire changes or brakes I only have the lift at 3-4 ft up so to operate the jack you have to crawl around under the car to get to the jack lift switch. Now I can raise the lift way up and then raise the jack and then lower it back to a good working height but that is just a pain. If I buy another jack I'll install it so the switch is toward the rear of the lift.

In addition to the RJ-45 bridge jack, I'm thinking about getting the JP-3 jackplate, it's only $140, plus the price of a pair bottle jacks.

It will be fine on any compressor really.. I run one on a cheapo HF 21 gallon compressor.

The thing that you have to take into consideration is that the rating of the compressor has NO bearing on the stored air in the tank, and it doesn't limit its flow either. The only thing that limits the cfm of the stored air is the fittings and the air hose.

That 125psi / 10cfm rating on your compressor is what the compressor pump will put out when it's running When the tank is full (pump off), like I said above, you're only limited by the connections between it and the air tool.

I'd skip the bottle jacks and plate.. you'll never use it. You can jack the vehicle up with the rj45, then just put jack stands on the ramps to hold it up.. no need for bottle jacks. Plus, you can get a top bar for the rj45 that has rails on it to allow you to slide on jack pad adapters, and rubber pads to lift right off that center bar without the arms

An RJ-45 and a JP-3 is the best combo for an HD-9 set up. The JP-3 will allow you to put jack stands anywhere you need them. Plus it makes a great place to put your oil drain containers, position lights, and hold tools/parts. I know it wasn't designed for this but I've also used my JP-3, with a chain around it, as an engine hoist.
