The introduction of Hydraulic Air Bottle Jack has simplified many industries. You have probably seen them used to lift cars, and maybe you have even tried to use them yourself. But how much do you know about Hydraulic Air Bottle Jack? How does a hydraulic jack work? What you need to know here is that hydraulic jacks are different from mechanical jacks because they can usually lift heavier loads higher. The main mechanism for applying force is usually through hydraulic cylinders-hydraulic jacks rely on the force generated by pressure to lift objects. Lift heavy objects by using plump plungers to move oil in the two cylinders. This causes the pressure in the cylinder to increase. Understand how hydraulic jacks work, the following is a brief introduction to the common types of jacks on the market
1. Types of hydraulic jacks
    Bottle jacks are also called manual jacks. Bottle jacks prove to be an easy way for individuals to lift vehicles for roadside repairs or inspections. Jacks have a wide range of sizes and lifting capabilities, ranging from 45 kilograms to several tons. The bottle jack uses a vertical shaft that supports a bearing pad that directly bears the weight of the load when the load is lifted.
  2. Trolley/floor jack
   Trolley jacks, also called floor jacks, are different from vertically operated bottle jacks. The shaft in the floor jack is horizontal-it pushes the crank connected to the lifting pad and then it lifts vertically. These jacks provide a greater vertical lifting range than bottle jacks and come in two main sizes-small and large.
After understanding the types of jacks, a question arises: how do you use hydraulic jacks?
Although there are a series of trolley jacks on the market, the basic operating principles apply to all situations. First, eliminate the pressure in the jack and reduce it completely. Make sure there is enough oil in the jack and it is working properly, then place it safely under the load and pump until it rises. Here are specific instructions on how to use each hydraulic jack:
1) Small hydraulic jack
Step 1: For a smaller size jack, first open the release valve and lower the jack completely. Step 2: Then remove the black cover on the top of the jack to reach the hydraulic cylinder. Below the cover and on the top of the plunger, you will see a small rubber gasket. That is the fuel plug.
Step 3: When the release valve is still open, quickly pump the jack handle several times.
Step 4: Then, slowly pinch the filler plug to release the trapped air. There may be a hissing noise when the air escapes-make sure you have not completely unplugged it.
Step 5: Close the release valve and check if the jack is operating correctly. In some cases, the air purification process may need to be repeated several times to achieve the best results.
Step 6: To refill the jack, simply remove the oil filling plug and fill it with hydraulic jack oil.
2) Large hydraulic trolley jack
Step 1: Twist the handle to fully open the release valve and lower the jack.
Step 2: Pump the jack several times with the release valve still open, and then keep the jack handle in the down position.
Step 3: Locate the screw in the more complete plug on the oil chamber and loosen it just enough to allow air to escape.
Step 4: Tighten the filler plug and carefully check whether the jack is working properly. It may be necessary to repeat the air purification process for maximum efficiency.
Step 5: You can remove the filler plug as needed to fill up or change the oil.
3) Bottled jack
Step 1: The process of removing air from a bottle jack is very similar to the process of using a small hand-push jack. First, loosen the release valve, and then pull the handle several times.
Step 2: Next, turn the bottle jack over so that the oil filling plug is directed upward and the equipment is in a horizontal state.
Step 3: Use a flat-blade screwdriver to slide the oil filler plug to one side to allow air to escape. Be careful not to damage the plug-as with all hydraulic jacks, you may need to repeat this process for best results. If you need to add oil to the bottle stopper, make sure to completely remove the filler plug, and fill it up until the oil is flush with the filler plug hole when the jack is upright.
