Hydraulic jack has become very popular at construction sites and for professional use, as well as for personal use. There are two types of nests: a bottle nest and an external nest. Both work in the same system, unlike the bottle opening, the side outlet has different internal seals and check valves. All jack operates in 6 parts: a tank in which the liquid is located, a pump for mixing the juice, a valve supplying flow to the master cylinder, at this moment the liquid piston lifts the piston and then returns the liquid discharge valve back to its original position, the tank. jack is robust and durable, and if you take care of them, you can extend their service life. It is ideal for transporting heavy equipment or building materials, as well as for personal use when replacing tires.

First, you need to get to know Jack. When using, be sure to use it on a flat, flat surface. If the surface is smooth, the crane may sink under the weight and not place it on an uneven surface, as it may deflect during lifting. There are times when the nest is removed from its position, and the load is unloaded, which is especially dangerous if you change the tire of the car. Also, remember that if you have a bottle slot, make sure you never put it on its side or the bar upside down, as this can cause malfunctions.
