4 Post Lift Recommendation
Discussion
Dam that iPhone business. Obviously two post!
Even though we have stored two cars in the garage occasionally I would be happier long-term with a four post lift.
As for versatility, you can’t beat a two post, far more access to the underside of the car. That’s why all garages use these for general repairs.

Hi all. I'm just installing a Model 1 lift from SJR. I'm utterly confused as to how these brackets attach to the lift for the warning buzzer activation and the manual makes no mention of them I'm pretty sure. Can anyone who has 1 explain where they should be attached?
Also (and I'll email SJR for some advice too) I ordered a jacking beam and got this.
Given the utterly crap Chinglish I think it means fill the box with hyd oil and connect to an air line? Anyone else got one who can advise? I don't think much to the jacking beam TBH. It sits 10cm proud of the runways, and the rocker switch/pedal is a cm or so higher than that so might be close getting my cars (TVRs) on/off.

I can't speak for hydraulic lifts, but a mechanical lift with screws and nuts cannot creep.
Two poster for access definitely, but yes it is a bit of a fag to position the arms.
All ramps whether mechanical or hydraulic are lowered into safety locks so they cannot creep over time !!Two poster for access definitely, but yes it is a bit of a fag to position the arms.

I have a Bradbury two poster, screw and nut, no safety locks, bought new in 2001. No hydraulics to leak, no cables to wear. It's 100% mechanical, one 3ph motor drives the top of one side by triple V-belts, a cross-shaft takes the drive across at floor level via a pair of bevel gearboxes to drive the bottom of the screw on the other side. Beauty of it is that you could cut the belts, remove the gearboxes or the cross-shaft and it would still stay exactly where it is. Zero creep due to the irreversability of a worm and screw system. Simples!
But nuts and screws can wear, and here it also has a cunningly simply, mechanical fail-safe device to monitor that wear and eventually immobilise the hoist. The main load-bearing nut on each side is connected by a linkage to a slave nut running just under it. With wear, the linkage progressively moves outwards as the two nuts move closer together, and a claw at the base would eventually lock out at the end of a descent and mechanically prevent another ascent. In 20 years of daily use these have haven't noticeably moved.
Best hoist design I've ever seen. If I was buying another I would have exactly the same again.

Sorry. should have said all modern Hydraulic lifts. Bradbury are great but I guess the cost will be prohibitive for anyone other than pro garages where lifts are up and down all day..

Again in all my time in the trade, using 2 post ramps, non had mechanical locks.
Mine has mechanical locks.Or just the type the garages I worked at had fitted.
The other massive advantage not previously mentioned (which those of you who use hoists will recognise) is that you don't have to go up to go down and you have very fine incremental control, handy when lowering a car onto an engine or a body onto a chassis.
Quite possibly. Mine is about four years old or thereabouts, maybe five. Yes, It may well be aimed more at the DIY market because of the price but it has had a huge amount of work, (mainly because one of my sons is a mechanic). Hasn’t missed a beat.

Hope you got it sorted?Must admit the SJR lift was the top of my list, but after trying to reach them on the phone 5 times and even sending messages on Fb etc with absolutely no success I went to Automotech.... In my mind I thought if they were impossible to reach when your trying to buy the unit, how effective would they be when i'm trying to install it?
