Anyone got a Rotary Bridge Jack? Need some info....

[TheFixer]

HI,

I've just bought a SJ-35 Sliding Bridge Jack for my Danmar D7 4-poster lift. I bought this jack as it was the only bridge jack that would (based on online dimensions) fit between the 'tracks' on my lift.

I had hoped to find a rolling jack, but couldn't find one narrow enough. However, I've found that even the SJ35 won't fit as intended - if it's set wide enough to slide along the ramps (as intended) it will catch on the tracks intended for a rolling jack. I've fixed this temporarily by fitting the extending sliders upside down, so it slides, but along the roller track.

So..I've decided to convert it to a rolling bridge jack. Browsing the web, it seems the best way would be to buy a wheel kit for a FC5412 Rotary Jack (see http://www.ebay.com/itm/261401838090. These fit inside a square section tube, and the springs compress when the jack is lifting a vehicle. In theory, I just find some square section, weld it in place and I'm done....

But...I need to know the distance from the top of these square section tubes to the track along which the rollers roll (this is to ensure that I'm not going to end up with the jack either hanging below the ramps, or too high to get my (very low) cars on the lift. I'd like to know this before buying the wheel kit (which isn't cheap...)

If anyone has a rotary bridge jack with these wheels, and can grab me some measurements I'd really appreciate it.

If I go ahead with this, I'll be sure to post details.

Thanks!
Steve

Bump.

Do you still have this Jack? Did you ever do the conversion? How do you like it overall?

Yes - still got the jack, and I'm very pleased with it.

However, no-one ever got back to me about the size of the Rotary wheels, so I've never done the conversion. I am using the original 'slide' pads, but fitted upside down. I also drilled holes through them and added some bolts to avoid them slipping out of the tracks.

It's a little tough to push with this arrangement, but nothing too bad.

Thanks for the quick response!

I am looking at ordering a 4 post with the SJ-35 jack. As I have been reading up about it, a few people commented that the Jack takes quite a while to get the car up in the air, and that sliding it around was difficult. I was just looking for some feedback

Sounds like I'll be ordering this setup then. Let me know if you have any other suggestions about the lift or accessories for it.

It does take plenty of 'pumping' to lift the car in the air, but I've not viewed that as a problem (if I needed a 'fast' jack I would probably have bought one that ran on air).

Also - it is definitely very heavy when sliding it. That's why I was considering purchasing the rotary wheels and converting it to a roller. However, it's not really been a problem, once you have it moving it has some momentum!

I'd forgotten about this post until your reply, which (I guess!) means that I'd forgotten I thought it was an issue. If you do decide to fit rollers to it, I'd be interested to know the results...

Thanks again for the feedback Steve!

If I do fit some rollers, I will update here for sure.
