If you have impact wrenches with you, is there a need to invest in a pneumatic torque wrench?
Impact wrenches
An impact wrench is a simple, efficient and powerful socket wrench tool. It gives high-torque productivity with very less effort by the operator. It gets acceleration with the help of a motor with ample energy stored in a rotating mass. It then provides the stored energy to the anvil that gives a high-torque effect. This operating system of the impact wrench does not need a reaction arm due to which there is no need for a reaction surface as well.
The design of the hammer is made in such a manner that the hammer will spin freely without being locked after delivering the impact. Only the motor here accelerates the hammer. Since this is the only reaction force getting back to the tool, the user does not sense any significant torque in spite of the fact that a powerful torque is delivering to the socket.
It is important that a hammer gets designed in such a manner that it allow the deliverance of a particular torque to help it revolve independently from the anvil. In case there is a requirement of a low torque, the tool will not hammer. Instead, it will effortlessly steer the fastener installing and removing it quickly. It depends on the maximum number of impacts occurring repeatedly that develops a loud noise and vibrations.
Impact wrenches do not deliver precise results for bolting. Therefore, they are primarily utilized for dismantling nuts.
- Pneumatic wrench
A pneumatic torque wrench is a gearbox attached with a pneumatic air motor. A reaction mechanism is present outside the gearbox that absorbs the torque and this is why the operator is able to use it with minimal effort. You need to keep a check in the air pressure that will help in adjusting the torque output.
In various mechanical situations, the nuts and bolts need to have a certain level of tightness to work efficiently. this is where the pneumatic torque becomes extremely functional. This tool helps in measuring the applied torque on the bolts in order to match it to the requirements of a particular machinery. Whenever a precise torque is required to be applied on a bolt or when an immovable nut needs replacement, then this planetary torque gearbox comes to the forefront to help with its multiplication ratios.Since both impact wrenches and pneumatic torque wrenches look similar, they are often mistaken to be the other. The primary difference lies in the fact that a pneumatic torque wrench works by non-stop gearing while an impact wrench functions through hammering. In the former case, all torque is maintained by the reaction arm and gearbox. With a reaction arm, a requirement of a reaction contact becomes important like that of a strong metallic surface or a nut.
A pneumatic torque wrench is perfect for bolting solutions due to its minimal vibrations and amazing repeating ability.
Applications of Pneumatic torque wrench
There are a few fasteners used in certain mechanical devices that require tightening to a certain level. This specified level is important for the component to work efficiently. A torque wrench comes to the rescue here. The pneumatic torque wrenches are sturdy and dependable tools made to deliver fast, accurate, and safe fastening for devices or components that need controlled bolting solutions. These are ideal for tough job site applications.
Pneumatic torque wrenches have special features like a handle-mounted adjustable pressure regulator, digital screen, dual speed mode, inline filtration, flip switch to loose or tighten the switch, two-hand operation, wheel bolting extension, etc. These are applicable in industries like Oil & Gas, Power, Mining, Manufacturing industries, Heavy Machinery, the Automobile industry, etc. Pneumatic torque wrenches operate fast giving an accurate result of +/-5% of torque range.
Advantages of pneumatic torque wrenches
Increase in productivity
- It rotates with high speed continuously to give constant torque output.
- There is minimum wear and tear due to the advanced low friction planetary gearbox design that even increases uptime.
- The operating system is much faster than hydraulic tools.
Ensures safety and protection
- Due to the modern ergonomic and almost zero vibration design, the risk of injuries, hand arm vibration syndrome, and exertion reduces significantly.
- It is perfect for indoor as well as outdoor applications due to its excellent and low noise operation.
- Controlled bolting has become supremely important due to the execution of critical applications where accurate fastening is the most important factor. Overlooking proper fastening might lead to injuries, damage or accidents.
Concise and simple to use
- The design of the pneumatic torque wrenches are quite simple to operate with a trigger style handle and a simple tightening or loosening switch.
- The torque wrench avoids over pressurizing by pre-fixing a certain input pressure.
Convenient to use
- These wrenches come with or without Filter-Regulator-Lubricator (FRL).
- They come with standard reaction arms with certain accessories and a wide range of custom arms.
- The pneumatic torque wrenches are all exported with a calibration certificate with a CE declaration.
Hand-Arm Vibration Syndrome (HAVS)
Hand-Arm Vibration Syndrome is becoming a common job-related disease in workers who often use vibrating tools in industries. In an advanced stage, the HAVS leads to a substantial disability affecting the quality of life. This disease requires proper and timely diagnosis. Therefore, the management at certain industries has reduced the utilization of vibration tools and prefers advanced noise-free tools that have no vibration when operating.
At ABS Group, we use tools that have no vibration and disturbing sound. They do not affect the user’s health delivering precise and good-quality results. With all the productivity-enhancing tools, the ABS has served the nation with dedication and perfection.
Get the perfect bolting solution with the Pneumatic Torque Wrench
When you decide to choose among the torque wrenches, judge them by two factors: the preciseness and the quality or material of the tool. You will most probably get two options and choose between the shut-off nutrunners or stall torque nutrunners. The primary difference between the two lies in the fact that a shut-off nutrunner switches itself off automatically after it reaches the fixed torque. This tool provides accurate bolting despite the qualification of the operator.
However, a stall torque nutrunner functions in a slightly different manner. The delivered torque changes with a change in air pressure. Therefore, it is important to set a desirable air pressure to allow it to apply the equivalent torque. The benefit of using this tool depends on its adaptability. As the torque pressure varies with air pressure, this tool provides a wide range of torque.
It depends on your requirement when you choose the right tool. For example, a shut-off nutrunner is perfect for a need for high-frequency operations. While a stall torque nutrunner operates perfectly in high-performance operations like required in the generation of wind-power. A stall torque nutrunner offers a higher torque range ensuring comfort of the operator.
Finally, the most important thing to remember is to add a pneumatic torque wrench in your toolbox. You can be sure to use an air impact wrench to make work easier with its repeated applications for fast and precise bolting.
