Craftsman hydraulic jack is a device that is used to lift heavy loads. This is possible by applying a force via a hydraulic cylinder. It uses the force created by the pressure in the cylinder chamber.
How to Understand Craftsman Hydraulic Jack?
The Craftsman hydraulic jack creates pressure by moving oil through two cylinders via a pump chamber. When the plunger is pushed down, the oil is transported into the cylinder chamber through an external discharge valve.
After, the suction valve closes, which results in built-in pressure within the chamber. This causes the piston in the chamber to rise and lift your heavy object. The process can be repeated multiple times to allow your load to be raised higher, and higher.
Why We Need Craftsman Hydraulic Jacks?
Craftsman hydraulic jack is a useful device that is used to lift up heavy vehicles. These jacks make work easier and save a lot of time. It can also be used for door stopper, cars, bikes, etc., and is small in size.
Craftsman hydraulic jacks are convenient to use. The business that involved lifting or unloading heavy objects can benefit from using this.
Craftsman hydraulic jacks are used for multiple purposes according to the needs and requirements of people. These are also needed in industries for lifting heavy objects. On the other hand, numerous hydraulic jacks are needed in cranes in order to increase its functionality.
Craftsman hydraulic jack is easy to install, but if you aren’t sure of putting it by yourself, you can try on consulting to an experienced person. It needs to be installed properly to function effectively, and also it should be put in a way that takes less space.
The Craftsman hydraulic jacks are easy to use and are lightweight devices. If you already owned this, you don’t need to employ heavy duty and to buy costly equipment to lift heavy objects. Craftsman hydraulic jacks make the process of lifting fast and effortless to make the process safe. Anyone can use this hydraulic jack by doing proper care of it.
How Craftsman Hydraulic Jack Works?

Craftsman hydraulic jack is simple to use, which lifts up heavy loads. This consists of two cylinders, which are of different sizes. The first one is larger than the other. These cylinders hold the hydraulic fluid. There’s a pumping system that consists of a pump to apply pressure on the fluid. The pump is either hand pump or mechanically powered.
To understand more how the Craftsman hydraulic jack works, read below.
Working Principle
Hydraulic fluid (oil) is the primary power source used by the Craftsman hydraulic jack. It creates pressure by the movement of this oil in two cylinders through the plunger. As I have mentioned above, the two cylinders have a different size. The function of the larger cylinder is to produce higher pressure. However, the pressure will build equally in both the cylinders.
First, the oil is moved into the pump chamber to pull back the pump plunger. Because of this movement, the suction valve will open up, and the oil will move into the chamber.
Second, the oil will now move into the cylinder chamber. Here, the pump plunger is pushed down. After this, the suction valve closes, which results in creating pressure in the chamber. Then, the piston of the chamber rises and will lift up the heavyweight.
Basically, the Craftsman hydraulic jack works based on the movement of the hydraulic fluid from the pump chamber to the cylinders. This movement can be done repeated times to lift the weight as high as possible.
Working Principle of Hydraulic Jack
The Craftsman hydraulic jack works on the Pascal principle. This principle is proposed by the French scientist named Blaise Pascal. According to him, any pressure applied to any point of a liquid enclosed in a container is transferred without loss other parts of the liquid.
This means that when a liquid is an enclosed container, the static pressure is applied to the walls of the container. This force is perpendicular to the walls and within the liquid. This means the external pressure is equally distributed in all the directions of the liquid.
