Using High Lift Jacks
Please see PART ONE before you read this section.
David Bowyer continues to explain the many uses of a high lift jack when out off roading.
Casting the Vehicle
The high lift jack is a very unstable unit. In off-roading terms this can be to your advantage. Imagine you are stuck well down in deep ruts with your axle diffs high centred.
No problem. Place the jack pad on ground below front bumper (make sure the ground is level), drop the base of the high lift into it and lift the toe up under the middle of the bumper. You now realise why you don't want your number plate protruding below. It's always a good idea to either place a block of wood between the toe and underside of the bumper or at least wrap some rag around the toe. This is to stop the toe from slipping sideways off the bumper which can happen so easily, especially when working in mud and water.
Ensure that the rack is upright and have a person stand each side of the vehicle slightly pushing towards each other. Continue to raise the vehicle as high as you can to a point where the two front tyres are well clear of the ruts. The vehicle must be left in gear and low ratio, first or reverse, with the handbrake on. You don't want the vehicle moving either backwards or forwards. Remember at this stage there is a certain amount of stability as the rear wheels are held in the ruts.
Ask your two helpers to 'stand clear' whilst you hold the top of the rack with one hand and the outstretched handle with the other. Simply then push the high lift over to the desired side taking the front half of the vehicle with it. The front wheels should 'land' onto the ground above the ruts. Sometimes, some additional help is required from one of your two assistants by way of a slight shove by pushing on the front wing in the appropriate direction. As the vehicle 'falls', only have one hand on the jack - the handle - pulling it out to the front to stop the jack from becoming trapped.
