Reliable support - a guarantee of safety
Car jacks are only designed to lift a car. But jacks are not reliable enough supports when working on the bottom of the machine. Never, even in a big hurry, should not be neglected correctly installed additional supports. Otherwise, self-repair work can be fatal.
For proper support of the machine, underlay wooden wedges and stones laid to the wheels so that the machine cannot move when it is lifted can serve.
What supports can be
As additional supports installed under the body, it is best to use wooden blocks and gaskets of various thicknesses. It is best to put standard triangular stops under the wheels, which securely fix the machine from rolling. You can put bricks, stones and other improvised materials under the wheels.
When lowering the machine from the jack onto the supports, make sure that the supports are installed under the box-shaped elements, stiffeners, otherwise deformation is possible. The upper part of the supports must not have too small a surface.
Overpass - the fastest option for lifting. The car is always safe. It is important that the overpass has a protective bar in front from moving. and from the sides - guides for the wheels.
The supporting surface must be pitted (troughs) for wheels. They serve as additional fuses against the movement of the machine.
