Jack is the simplest lifting equipment with small lifting height (less than 1m). It has two types: mechanical and hydraulic. The mechanical jack has rack type and screw type. Due to its small lifting capacity and laborious operation, it is generally only used for mechanical maintenance and is not suitable for bridge repair. Hydraulic jack has compact structure, stable work and self-locking function, so it is widely used. Its disadvantage is that the lifting height is limited and the lifting speed is slow.
According to different manufacturing principles, there are mechanical jacks and hydraulic jacks. The principles are different. In principle, the most basic principle of hydraulic transmission is Pascal’s principle, that is, the pressure of the liquid is the same everywhere. In a balanced system, the pressure exerted on the smaller piston is smaller than that on the larger piston The force is also large, which keeps the liquid still.

The small bevel gear drives the big bevel gear and makes the lifting screw rotate, so that the lifting sleeve can be lifted or lowered
to achieve the function of lifting tension. But not as simple as hydraulic jack.
The difference between horizontal jack and the the vertical jack is: easy to operate, large lifting capacity of horizontal jack, suitable for large vehicles. The vertical jack is easy to operate and suitable for trolley.

Vertical jack: using hydraulic principle, different from traditional mechanical jack, it is a truck mounted lifting tool with simple operation, safety, reliability, labor saving and strong liquidity.
Today, as long as in the parking lot or gas station, you can see the hydraulic crane, using it to exert the strength of a child can lift a car.
