Hydraulic pullers are tools that use hydraulic pressure to exert a large force on an object in order to move it or remove it from its current location. They are often used in automotive repair and maintenance, construction, and other industries where it is necessary to lift, move, or remove heavy objects.

Here is how a hydraulic puller works:

  1. The puller consists of a hydraulic cylinder, which contains a piston that can move back and forth inside the cylinder.
  2. The piston is connected to a rod, which extends out of the cylinder and is attached to a pulling tool, such as a fork or a claw.
  3. To operate the puller, the user first connects a hydraulic hose to the puller’s cylinder. The other end of the hose is connected to a hydraulic pump, which generates the hydraulic pressure needed to move the piston.
  4. The user then activates the hydraulic pump, which pushes hydraulic fluid into the cylinder and pushes the piston outward. This causes the rod to move outward, pulling on the attached tool.
  5. The pulling tool is designed to grip the object that needs to be moved or removed. As the rod extends outward, it exerts a strong pulling force on the object, pulling it out of its current location.
  6. When the object has been moved or removed, the user can deactivate the hydraulic pump and release the hydraulic pressure, allowing the piston to return to its original position. This retracts the rod and releases the object.

Hydraulic pullers are very powerful tools that can be used to move or remove heavy objects with ease. They are often used in situations where it is difficult or impossible to use manual labor or other mechanical means to move the object.
