Hydraulic Pullers: What Exactly Are they, and Why Do They Function?

The process of removing bearings is performed by using the hydraulic puller. Hydraulic pulling is carried out using the hydraulic jack and the ability to move a mechanical jaw puller. The plunger rotates out whenever the pump is activated. The mechanically driven jaws are set beneath the bearing when it is turned off again.

Pullers are available in a variety of sizes. Which one to select is based on the application and size of the item to be removed? The dimensions of the item you’ll need to be pulled or retrieve are just some things to consider. The force required is a factor during the extraction process that is influenced by the age of the part, and the amount of pressure could cause damage or breakage to the item.

A 100 ton hydraulic puller is a tool specifically that is designed to extract or remove parts with a tremendous amount of force. It is often used in industrial processes where the disassembly and extraction of large and complicated components is necessary. With a pull capacity of up to 100 tons or 200 000 pounds, it can tackle complex tasks such as removing gears, bearings, pulleys, and other tightly-fitted parts.

What is the process?

The hydraulic puller is moved straight forward in conjunction with the start rod for hydraulics, and the rod itself doesn’t move. The seat of the hook is adjustable forward and backward directly using the thread. In operation, so long as the handle moves between two directions and the hydraulically powered rod is moved forward, the hook will then retreat to release the object being pulled.

Hydraulic pullers are a great new tool that can replace traditional pullers. Hydraulic pullers are lightweight in design. It is flexible and adaptable to use, lightweight in weight, compact in dimensions, simple to carry, low-cost, and non-slip. It’s not restricted to location and direction (0-360deg) and location (2 claws, three claws). It is widely used for dismantling discs and flanges, gears, pulleys, and bearings.

Safety precautions for the operation of a hydraulic puller

Before using the hydraulic puller, the appropriate tonnage must be chosen based on the diameter of the outside of the object, its pulling distance, and the force of the object being pulled. Moreover, it must not be overloaded to prevent damage.

The hydraulic puller utilizes oil as its medium, and maintenance of the oil and the tools should be carried out correctly to prevent blockage or leakage of oil, which can impact the effectiveness of the puller.

To avoid damage to equipment that is due to overload, there’s an overload unloading valve inside this hydraulic system. Suppose something being pulled exceeds the maximum load it is designed to handle. In that case, an overload valve is activated to unload, and a more considerable tonnage hydraulic puller is utilized instead. If the hydraulic puller is not in use, it should be rotated at least three times per month without being loaded.

How to use it

1. If you are using the hydraulic puller, insert the end with the slotted handle on the stem of the oil return valve and then close the stem of the oil return valve in the clockwise direction.

2. The hydraulic lever hook’s seat to ensure that the claw hook grips what is being pulled.

3. The handle is put into the hole in the lifter, and the piston’s starter rod is moved forward and back to move forward smoothly; then, the claw hook retracts in a manner that allows the object that is pulled.

4. The distance of the piston’s beginning rod in the hydraulic puller can be 50mm. Therefore, the extension length shouldn’t exceed 50mm during use.

5. To retract the piston’s start rod, make use of the slotted end on the hand to loosen the rod for the oil return valve in a counterclockwise direction, and the rod that starts the piston slowly retracts as a result of the force that the spring.
