How to Select Hydraulic Pullers Safely

1. By exerting controlled pressure, the hydraulic puller system aids in the effective removal of press-fit pieces. They are actively used in many activities since they are meant to extend the life of applications through correct component removal and service. As a result, they're useful for removing wheels, gears, couplings, flywheels, sprockets, and a variety of other components. Furthermore, it removes the dangerous methods of heating, pounding, or prying various components to remove them, limiting the damage done. Manual pullers can do a good job, but they're only suitable for little projects and are inefficient when compared to hydraulic pullers. When it comes to selecting any form of mechanical equipment, safety is a major factor, and hydraulic pullers are no exception. So, in this article, we've discussed various factors to consider while choosing a Hydraulic Puller. 1. The puller's size: Reach: The reach and spread range of a hydraulic puller are the most important factors to consider when purchasing one.

2. The reach is the distance between the cage base and the pulling surface of the jaw. The distance diminishes as the jaw spread widens. The length of the reach must be equal to or larger than the length of the portion you're pulling. Consider the following scenario: If the tonnage to shaft diameter ratio is 10:1, a 15-ton puller should be used if the shaft diameter is 1.5 inches. If the shaft diameter to center bolt diameter ratio is 2:1 and the shaft diameter is 1 inch, you should use a half-inch center bolt. Spread range: This is the distance between the cylinder and the jaw's pulling surface multiplied by two. When the cage goes back, the spread range tends to rise, and when the spread moves forward, it tends to decrease. The reach of a hydraulic puller reduces as the spread widens. 2. Choosing the Pump: When utilizing a hydraulic puller, remember that control is more vital than speed. As a result, as a user, you must be aware of the types of pumps that will remain under your control and perform as intended. Hydraulic pumps are divided into two categories. Manual Hydraulic hand pump: You can manage the gradual application of pressure with a manual hydraulic hand pump and a puller to keep optimum control while executing the operation. To get the most out of the hydraulic cylinder, make sure the usable fluid capacity is sufficient.

3. Electric hydraulic pump: If you're going to use an electric hydraulic pump with the puller, make sure it's one that can keep control at all times. Only when the puller's attachments are in perfect working order can the job be completed correctly and without causing any damage to the parts. Not only that, but it also takes into account safety precautions. As a result, make sure the attachments are in good working order. 3. Equipment Safety: You should always check to make sure that the puller and anything you are going to pull is stable and secure before beginning work with it. So that components do not fall out of the mount, this is crucial. Other equipment must be used in addition to the puller in order to ensure stability. This prevents damage to the user and the surrounding area.

4. 4. Puller types: There are two varieties of pullers available, each with its own set of characteristics: two-jaw and three-jaw. When compared to a two-jaw puller, a three-jaw puller maintains a consistent force around the object during pulling. A three-jaw puller, on the other hand, cannot be a decent choice if you have limited space. In any case, you can select one based on the type of task you're doing. 5. Mechanism of locking: Pullers with a locking mechanism keep the jaws from falling off the workpiece while being pulled. As a result, don't neglect this function, as it serves as a safety precaution. It's critical to select the right puller for a simple pulling job that gets the job done correctly. So, these are the various things to consider while selecting a hydraulic puller.
