Lifts and cranes are made up of different parts and parts, and the lift jack or hydraulic jack is one of the important and essential parts. In fact; The main part in elevators and elevators, which causes the cabin and floors to move, is the hydraulic jack. The working mechanism of the hydraulic jack is very simple and it is used in various equipment and devices.
Hydraulic lift jack
Hydraulic lifts consist of various mechanical, electrical and hydraulic components. In the power equipment sector, the hydraulic jack is a very important part that must have the necessary features for high-quality and safe movement of the lift. In this section, the application, structure, main specifications and types of hydraulic lifting jacks have been examined.
How to work hydraulic jack
There is a large cross-sectional area in the part of the hydraulic jack that has the mass of the object on it, which requires more force. The lower cross-section is also the part of the hydraulic jack that moves the oil through pumping, which requires less force. It means that according to our force and power, we need to apply a small force to a smaller cross-sectional area, less force and a larger cross-sectional area.
In hydraulic jack, the jack handle It is a secondary type of leverage which has a unique mechanical property of its own, this handle is responsible for increasing the driving force. A useful force from this handle enters the hydraulic jack, which increases this force. This is divided into 2 parts.
Application of hydraulic jack
Hydraulic power has been used for many years for the convenience of lifting and moving agricultural machinery. Taking advantage of this power is used to control and how to sit on the tractor in modern machines. In all cars, to get help to move the car over the pothole or to move the tires from different jacks. they benefit, which have different types; All examples of hydraulic jacks have a wider application that today they are widely used in passenger cars and are still considered an essential part in heavy vehicles.
In particular, hydraulic jacks are used in mining and road construction machines, elevators, dumpers, cranes, forklifts, etc., and are also very widely used.
One of the important reasons for the importance of using this hydraulic jack is its shape and The structure is almost simple along with the very high power that they create.
Hydraulic jacks have many importance and applications in industries, which can be briefly stated:
Lifting and moving Heavy machinery, cranes, use in refineries, underground excavations, architecture and tower construction, all vehicles and...
There is a great diversity and also a wide range in the use of these jacks, which has made jacks Hydraulics can be produced among thousands of different models and types with different lengths and diameters as well as different designs.
The structure and components of the jack
The hydraulic lifting jack consists of a hollow cylinder as a cylinder made of seamless steel pipe and a solid steel rod or pipe of appropriate thickness as a shaft, which moves vertically in two directions with the shaft oil flow inside the cylinder. slow.
Hydraulic lift jack
Hydraulic lifting jacks, although they have relatively the same structure, are classified into different types. Conventionally, the types of lifting jacks are classified based on the method of connecting the jack, the installation position in relation to the floor of the lift and also the number of jacks. In fact, the criteria for classifying lifting jacks is the types of drive systems of hydraulic lifts. Structurally, jacks are divided into two main groups, single-stage lifting jacks and telescopic jacks. In terms of the assembly method, these jacks can be implemented in one piece or two pieces.

The price of the lift hydraulic jack
As we said, the hydraulic lifting jack is considered one of its main and essential parts, and the price of the hydraulic lifting jack can have a wide range, depending on the manufacturer's brand. The price of hydraulic lifting jack, if it is produced by domestic and Iranian brands, is much lower than the price of foreign hydraulic lifting jack. Among the foreign types, some brands are more expensive than others, and this is due to the difference in quality.
Iranian hydraulic jack is more useful due to its reasonable price. In addition, we must remind that the price of the hydraulic jack lifting from the side is completely more economical and economical than the types of hydraulic jack lifting directly from below.
