Recently bought a Bushranger airjack at Melb. 4WD show - I was told the smaller 3 tonne model (vs 4t) would still do the job on a 98 Pajero but trying it on the weekend it struggled to lift the wheels off the ground - positioned in the centre under the side step it looked as though there was insufficient height to raise the wheels. Does anyone know if I was given a bum steer with the 3 tonne model or is there a couple of basics I may have not followed??

Does not feel good - for the sake of $50, the height of the 4 tonne would make a huge diff - thanks for your compassion!

adrian,

air jacks lift a weight, not a height. If your vehicle is under 3 tonnes (loaded), your jack is ok. Use spare wheel (unless needed for changing!), bits of flat wood or pile a large stable mound of dirt under the bag. Remember in most situataions your vehicle will be up to 18" lower than normal when you actually need to use the jack.
Try avoiding these situations....
good luck have fun - Go the Sube

Have a 3tonne Bushranger and lifts the rear wheels of my '84 Rangie completely off the (level)ground, did you try upping the idle speed, agree with rich's reply.

thanks to you and Rich. I'll try with increased idle speed and let you know - did you find the location of the bag was critical to lifting the wheels off the ground ?

I wanted to test lifting capability, so in my driveway I placed a 1m x 1m reinforced rubber mat between the jack & rear step/towbar area. I had to run engine at approx. 2k rpm & lifted rear wheels just clear of ground. My Rangie is equipped with sill tanks, which makes it ideal for placing the jack for side lifts. I have found the jack is far easier to use & more stable than a highlift when on uneven/soft ground conditions. The 4tonne was not available when I bought my jack some years ago, but am very happy with the 3tonne.
