Trolley Jack Advice Needed.
Need some more help from the D3 experts?
I got a flat today, and without thinking used the trolley jack I got for my last 4x4. Changed wheel no problem, then noticed that I had used a 2 ton jack. It worked but I was wondering if I should get a 3 ton jack. I do not do any maintenance on the D3, so jack will only be used for changing the odd flat. Would the 2 ton do the job safely, as I am only lifting 1 corner at a time.
PS It carrys a lot of weight.
Some 2 ton jacks when extended tend to be a bit unstable, due to the height the D3 need to be lifted if you use the factory jack point. If you are jacking under the wishbone you are probably ok,
Air bag are good especially on soft ground.
I have a 3 ton jack with a modified mount that fits into the chassis rail factory jack point, the large size make it fairly stable, but I do use at least one axles stand.

Thanks SM
I just finished reading your post about the conversion to your jack, very nice. You look like someone that does a lot of work on your D3. The problem is the weight of the jacks, looking for a 3 ton jack on the net, I noticed there is quite a bit of weight difference between them. My D3 is packed full of tools so I don’t want to burden here with any more weight, if I can help it. I did jack it up using the wish bone, and had no problems, but I did change the wheel VERY quickly in case of a collapse.

this is/was a much discussed topic but if you consider that D3 wheels are rated at ~940kg, then if you are lifting just one corner under the wishbone with a 2T trolley jack then you are well under the rating but it's worth remembering that it's not a recommended LR jacking point.
that's how I always change my wheels though....and theeeeennn......???

Had to find a conversion chart there. So jacking with wishbone at 1 corner with 2 ton jack is ok.

there was a long running thread on trolley jacks, but I'll add one comment. I have a 3ton quicklift trolley jack from machine mart (its a clarke stongarm, the highlift version), it was quite inexpensive (approx £49 if I recall correctly), and ITS RUBBISH. It twists (the main frame) and creaks, and looks decidedly unsafe, to the extent that I've gone back to using the LR supplied jack. I guess its another example of you get what you pay for, so if you are going to buy a new trolley jack, buy a good one.

I also bought the machine mart 3t quick lift one and agree that it is poor, it takes a lot of effort to raise and I always feel it is going to break under the strain. Lifting under the wishbones isn't too bad though but trying to lift at the recommended points with this jack is scary. It doesn't help that I have nowhere flat to jack on and have to do it on a sloping driveway 2020 BMW X1 18d XDrive X-Line Auto

I think the rule that lifting kit has to be made to is its collapsing/breaking point must be twice its working load. So for a Trolley jack to be rated at 2T it has to be able to actually bear 4T, hence you should be able to safely lift the full rated weight of the jack. Unless you find a way to put the whole vehicle weight on the jack it should be fine, even if lifting one end (under towbar mount for instance).Cheers

The Clarke Strong Arm CTJ3000G is the better one [as in SM's pic]
I got one, it's much sturdier and around £65 incl vat.
BUT, it's not a 'quick lift' - I don't need that, I'd rather take my time to position correctly and then gently raise.
Oddly it was harder to find in the Machine Mart website than the other models....... always on the road less travelled 🚧
Also more difficult to find one in the stores - had to order mine, it is much much stronger than the quick lift, in fact the guy at Machine Mart said they had had most of the quick lift ones back, and he wouldn't use one.
The Heavy duty 3ton is not light, or quick in operation but is sturdy, put a thick plank of wood under most eco boxes and it will lift the whole car in one.
I have seen your mail ronp I will send you the dimensions.

I went for the quicklift/hilift (CTJ3000QL) one as I thought the "standard" clarke 3 ton hadnt got enough lift height for the D3.

attached is a word doc showing the sizes used (plus 2 modifications) for the jack / chassis adaptor for the clarke heavy duty 3 ton jack. it may fit others.
I can get these made, but it's by a sub con toolmaker so they aren't cheap.

Shiny, what kind of ballpark are these 'not cheap'?Dr. Ian Malcolm:
