Three kinds of classification and introduction of Jack

1. First of all, I'll tell you about the screw jack. Its thread has no self-locking purpose. According to the release of the brake, when lifting, the weight can drop rapidly by itself, which greatly shortens the return time. Its small disadvantage is that its structure is somewhat complex. Its advantage is that it can be used for a long time and can lift 100 tons of weight. It is widely used in the market.

2. The second is the hydraulic jack, which is a medium in liquid transmission. It plays the role of transmitting and converting power. When used, it also plays an obvious role in lubricating / cooling / flushing / anti-corrosion of various components of the hydraulic system.

3. Finally, there is the electric jack. As the name suggests, the electric jack is a charged automatic device, which works by starting the jack with voltage. This device keeps the pressure inside and prevents exceeding the pressure. In case of overpressure, the jack will not return to the original position by itself, which plays a protective role and has a high safety factor.
