Many people have no idea about jacks, especially some who don’t know how to choose a jack for cars. If jacks are classified according to their working principles, they are mainly divided into two categories, one is mechanical jacks and the other is hydraulic jacks. So which category of jacks do car jacks belong to? Next, let us explain.
Jack products are not only used in cars but also in construction projects. If you choose a jack for use in a construction project when purchasing, it is a bit inferior on the one hand. On the other hand, the price is also higher.
How should I choose a jack? Introducing two products, one is a scissor jack and the other is a horizontal jack. These two are currently commonly used car jacks. The appearance of these two jacks is still different, which is easy to judge.
The scissor jack is a mechanical jack with a special structure. Its working principle relies on screw pair transmission. Because of its appearance, it is called a scissor jack. The overall shape looks like a quadrilateral structure. Through transverse screw transmission, the entire quadrilateral structure is deformed and the upper and lower diagonals are enlarged, thereby achieving an increasing effect. This also takes advantage of the quadrilateral's easy deformation and ease of use.
A level jack is not a mechanical jack, but a hydraulic jack. Its working principle is Pascal hydraulic transmission principle. The horizontal jack has a lower chassis and higher stability. Compared with scissor jacks, the structure is much more complex. With the protection of the outer shell, the internal mechanism is more precise, so the price is slightly higher. The advantages of horizontal jacks are large load, good stability and safer use.
Scissor jacks and leveling jacks are two commonly used vehicle jack products. One is simple in structure, easy to carry, and cost-effective; the other is well-designed, has large load-bearing capacity, and is highly safe. It can be said that each has its advantages. Car owners can judge and choose a jack based on their actual situation.
