What are the types of car jacks?

Car jacks are essential tools for car repair and maintenance, and different types of car jacks have different characteristics and applicable scenarios. Below, we will introduce you to the four common types of car jacks in detail.

1. Rack jack: It consists of three parts: a rack, a gear and a handle. The rack is raised and lowered by shaking the handle. It is small in size and easy to store. However, its supporting weight is limited and it is not suitable for vehicles with heavy loads.

2. Hydraulic jack: It is divided into general hydraulic jacks and special hydraulic jacks. It has a fast lifting speed and a large load-bearing capacity. However, because of its complex structure and inconvenient to carry, it is not common in ordinary car repair and maintenance.

3. Screw jack: It relies on the principle of self-locking of threads to support heavy objects. It has a simple structure, but it supports a large weight, a slow lifting speed and a fast descent.

4. Inflatable jack: It uses exhaust gas to inflate, which is special and not common in ordinary car repair and maintenance.

Choose according to different usage scenarios and needs.
