Rack can be divided into diamond structure and humanoid structure, and the most common one is diamond structure, so the diamond structure is mainly introduced here.
Open the jack, which is a diamond, with the support part above and the base below.
The base faces downwards, and the supporting part supports the automobile chassis. Put the jack into the space gap between the chassis and the ground, and use the hub bolt wrench as the rocker to shake it directly.
Screw jack is relatively simple. Put the base directly on the ground, support the vehicle chassis with a bracket, insert the hub bolt wrench into the small hole as a rocker, and then shake it.
Screw jack is generally used for SUV with non-load-bearing body structure. The shape of the screw jack is the same as that of the pillar.
There is a special place to place the jack on the automobile chassis, and there is a special sign in front or behind the side beam of the automobile. This marked place is the position of the supporting jack.
When using the jack, you can put the spare tire under the chassis. This is to prevent the vehicle from falling suddenly and have something to support it.
