The ARB unit would pull posts or push things away from the jack base? ( though I am not sure if the hydraulics will work laying over, which is an interesting tech question or test for the owners)Apart from normal lifting I have used mine for clamping and spreading and winching, Pulling posts out of the ground and for pushing things,
I can load my Hi-Lift on the roof rack or inside the vehicle, The Hi-Lift is not just a Jack it is a problem solver, It always makes me laugh when So called macho guys complain about the weight of things, It does not matter whether it is Rifles, Metal Detectors or jacks, Kind of makes a mockery of the image they portray,
I didn't mention weight in my post? I mentioned size. A 48-60" hi-lift jack is just cumbersome to store in a smaller vehicle. It just is, I don't care if it weighed 5lbs instead of 40lbs, it is just a large piece of gear to store on/in a vehicle. Personally, I know enough about vehicle dynamics and weight distribution that I don't want that much weight up high mounted on a roof rack or behind the rear axle if I can help it. After carrying and not really finding many actual uses for a hi-lift style jacks, for years...I moved on. I'll take my non-hydraulic double extending Toyota bottle style jacks these days. The hi-lift just sits in the garage gathering dust. I've been able to use the bottle style jack in more situations vs the hi-lift style jack. We had an excellent example of this on a Rubicon Trip last year. I will dig up a pic. The hi-lift was useless....the little bottle jack saved the day.....
It always makes me laugh when people throw out random solutions to things without thinking through all the ramifications.
