How Does a Torque Multiplier Work and What Is It?

How Does a Torque Multiplier Work and What Is It?

A torque multiplier is an instrument that offers an advantage in mechanical terms when tightening or loosening bolts and nuts. They’re utilized to enhance the amount of torque and allow workers to take apart or assemble heavy machinery or vessels quickly. They can be used to build constructions as well.

Torque multipliers represent the definition of “work smarter, not harder.” They offer enhanced safety, more precision, and higher efficiency and productivity. In normal conditions tightening and loosening heavy-duty fasteners can be exhausting work.

The hydraulic torque multiplier can be a valuable accessory to your toolkit. It gives you the force to turn nuts, bolts, and screws effortlessly. One slight push could create an impressive torque, making it a superior, safer alternative to extended handles and “cheater bars,” which could create a safety risk if the tool fails during use.

Types of Torque Multipliers

To use a torque multiplier safely and effectively, you should use the correct multiplier to accomplish the task you have to complete. There are three torque multipliers, each suitable for a specific use.

  • Hand torque multipliers

Hand torque multipliers are highly efficient in field-based service applications. Because they don’t need an external power source, they can be utilized in any location where power isn’t available or unreliable, such as at sea or in mines.

  • Pneumatic torque multipliers 

These devices utilize compressed air to increase the force applied to bolts and nuts. They’re fast, powerful, accurate, precise, and efficient. However, they require access to compressors to function, which limits their usage to extensive manufacturing facilities with the necessary infrastructure to enable their operation.

  • Electric torque multipliers

Electric torque multipliers use AC power to loosen or tighten fasteners, and a microprocessor controls them. They can outperform hand multipliers regarding speed, making them an excellent choice for field service. But, they’re not preferred to pneumatic multipliers because of the power source available instead of compressed air.

The Benefits of Using Torque Multipliers

Whatever type of fastening is used, torque multipliers can simplify your work and make it less laborious, improving manufacturing efficiency. Other benefits of using the torque multiplier are:

  • They’re more secure than handles that are extended. Torque multipliers can cut down the length of the lever needed to tighten or loosen fasteners several 5, 25, or even 125, depending on the kind of multiplier.
  • They are accommodating for unlocking bolts that are stuck.
  • It is possible to apply the appropriate amount of torque to an application.
  • They take a lot of physical strain from the tightening procedure.
  • Torque multipliers offer a slower and more precise process for fastening that ensures the fasteners aren’t too tight or loose. In turn, they can reduce the requirement for adjustments and repairs, improving productivity and efficiency for workers.

Final Thoughts

In conclusion, a torque multiplier is a remarkable tool crucial in various industries and applications. Utilizing a gear mechanism allows users to multiply the torque applied to a fastener, enabling the efficient tightening or loosening of stubborn or high-torque bolts and nuts. The torque multiplier’s simple yet effective design makes it a valuable asset for mechanics, engineers, and individuals working with heavy machinery or equipment.
