Hydraulic jacks are divided into the following types:
🔰 One-way jack 🔰
The size of the diameter of the handle and the piston is the same. These jacks are designed in such a way that oil can enter and exit from only one path. When the oil is directed to the piston head, the jack will open and have the ability to lift objects. In order for the jack to close, it is necessary to put a force (load) on the piston handle. That is, one-way jacks can only lift a load or heavy object and there is no force to go down.
🔰 Hydraulic one-way jack 🔰
In this jack, the diameter of the piston is greater than the size of the piston handle. There are two entrance and exit routes for them. One duct is located at the beginning of the cylinder and the other duct is located at the end.
The duct located at the end of the piston is the place of air entry and exit, and the one located at the beginning of the piston is the place of oil entry and exit. In terms of performance and efficiency, it should be said that these jacks are like one-way hydraulic jacks.
That is, they are only used for lifting heavy objects and do not create force to lower the desired object.
🔰 Two-way jack 🔰
In a two-way oil jack, the diameter of the piston is greater than the diameter of the piston handle. In this type of jack, there are two inlet and outlet channels for oil. Oil will enter from one opening and exit from another opening. In this type of jacks, power will be applied to lift and lower objects. Hand jacks are also popular. which is one of the easy and convenient ways to lift vehicles for service or inspection on the side of the road or in repair stations is bottle or manual jacks. Manual jacks are made in different sizes with different applications. . They range widely in size and lifting capabilities from forty-five kilograms to several tons. Bottle jacks use a vertical shaft that uses a bearing pad that can directly lift the weight. lift off the ground. One of the most common hydraulic jacks are bottle jacks. The shape of these jacks is in the form of a milk bottle, because of this similarity they are known as bottle jacks. Learn more about their uses. These jacks became very popular among buyers in the early 1900s when the automobile industry began.
These jacks lift the weight directly from the ground by a vertical shaft. But if we want to talk about the use of these jacks, we must say that these jacks are mostly used in the automobile industry. But these jacks are also used in the medical industry to raise and lower patients.
These jacks are also used in industrial applications, they can be used to lift heavy loads as well as large agricultural machines. take
🔰 Trolley/Floor Jacks 🔰
Trolley jacks are also known as floor jacks. Floor jacks are unlike bottle jacks or manual jacks that operate vertically and their shaft is vertical. In Trolley jacks, the shaft is placed horizontally on a crank that is connected to a lifter, and with pressure which enters and lifts the object vertically from the ground. These range jacks are more useful than manual jacks and are made in small and large sizes.
🔰 Jack Toe life Hydraulic Jacks🔰
Toe life Hydraulic Jacks are a special type of hydraulic cylinders that are used to lift machines whose level is low with the ground.
Where floor jacks and manual jacks cannot be used due to the low level of the car with the ground, Toe life Hydraulic Jacks are used.
🔰 Scissor Jacks🔰
Scissor Jacks are one type of hydraulic jack (hydraulic cylinder) that these jacks are made compactly. Scissor Jacks use a mechanical screw. The rotation of the scissor jacks leads to the raising and lowering of the arms of these jacks. depending on the position and mechanism of these jacks, the arms are extended or retracted.
🔰 screw jacks 🔰
another of Types of hydraulic jacks are screw jacks. which use a vertical screw mechanism to raise or lower the jack. Some models of these jacks have the ability to adjust the wrench, while others use a surface inserted through a hole in the jack to allow additional mechanical use when turning the screw.
🔰 Wheeled jacks (Ratchet Jacks) 🔰
Wheeled jacks use snail and hanging mechanism to raise or lower the load. Sometimes wheeled jacks The real type were the jacks that the car manufacturers gave to the buyers with their vehicles for the buyers to use when changing the wheels of their cars.
These jacks along with the wheel wrench as The jack handle was given to the buyers. With the development of unibody construction and the elimination of metal hitches on vehicles, wheel jacks became less popular than scissor jacks because they had less specifications than scissor jacks. And they could be overturned under the body of the car.
