When to Use an Electric, Pneumatic, Battery or Hydraulic Torque Wrench
If you’re in the manufacturing or construction industry, chances are you’ve heard of a torque wrench. It’s an essential tool for tightening fasteners securely to ensure projects stay sturdy and durable over time. But what kind of torque wrench do you need?
We cover everything you need to know about electric torque wrenches, pneumatic torque wrenches, battery torque wrenches and hydraulic torque wrenches so that you can decide which one is best suited for your project.
We discuss their features as well as the unique advantages that each type provides – all so that when it comes time to buy a new torque wrench, you’ll be able to make an informed decision!
Overview of electric, pneumatic and hydraulic torque wrenches
Electric, pneumatic, battery and hydraulic torque wrenches are specialised tools used for the purpose of accurately tightening or loosening fasteners such as nuts and bolts:
- Electric torque wrenches typically have a 110-V or 220-V plug in which is driven by a precision electric motor. This used in conjunction with a gearbox allows for continuous and accurate torque to be applied. The digital sensors and computer in this system allows for easy user interface, data collection, digital display of torque read out along with auditing features. The computers allow for the E-RAD system to be the most accurate torque tool that RAD Torque Systems offers.
- Pneumatic torque wrenches are gearboxes coupled with a pneumatic air motor. These usually require an air supply with 100 PSI and 30-50 CFM’s in order for the tool to perform optimally and accurately. Technicians would adjust the torque output by the provided air regulator that comes with all RAD Pneumatic Series tools. This allows for quick adjustments to be made.
- Battery Torque Wrenches combines the convenience and speed that the other gearbox style torque wrenches offer but now with true portability that no longer requires a plug-in electrical supply or a tow-behind air compressor to be taken out to jobsites. There are different variations of Battery tool options but all have a digital display screen that allows the technician to make in the moment adjustments to torque and angle requirements with nose hoses or extension cords needed!
- Hydraulic torque wrenches have been around the industry as the longest solution for high torque requirements. The hydraulic wrench is typcically supplied in two styles, a square drive and a low-clearance option. These compared to gearbox tools have the potential to have larger torque outputs as there are models on the market that cover torque ranges of 50,000 and even up to 100,000 ft lbs. These units are powered by a 10,000 PSI hydraulic pump that is either driven by air or electricity.
Advantages and disadvantages of the electric torque wrench
Electric torque wrenches are incredibly valuable tools for any project requiring precise torque control. They have the advantage of providing both speed and accuracy, as well as the ability to access hard to reach areas that other manual tools cannot. When used properly and with great care, electric torque wrenches can save time and energy on a variety of projects.
However, you must be careful that the tool is calibrated correctly in order to avoid under-torquing or over-torquing a project, a situation which can result in damages to machinery or components.
Additionally, electric torque wrenches require minimal set-up time and annual maintenance in order to perform accurately throughout each assignment. These factors should be carefully weighed by anyone considering using an electric torque wrench for their project needs.
Advantages and disadvantages of the pneumatic torque wrench
The pneumatic torque wrench is an essential tool for many industries, as it provides the precision and accuracy needed to securely fasten bolts and nuts. It is the preferred choice of professionals due to it being lightweight and easy to use.
Furthermore, its durability ensures long-term functionality. However, this type of wrench does require an air compressor to be operational and should always be handled with caution since improper operation can lead to over-tightening or under-tightening of nuts and bolts.
What’s more, a lack of proper safety precautions could result in injuries from flying debris or compressed air leaks. Although there are some potential hazards associated with using this tool, the advantages clearly outweigh the disadvantages when operated safely by a professional using the appropriate equipment.
Advantages and disadvantages of the pneumatic torque wrench
The battery torque wrench is quickly becoming the mechanic’s #1 tool choice when it comes to industrial bolting applications. It’s instant readiness and quick change torque settings have made it an industry favorite. The current generation has come a long way since previous of battery powered torque wrenches which include a brushless motor that allows for much cooler operating which allows the tool to perform longer with out it needing to shut-down to cool off. The battery tools of today now offer many if not all the features of the RAD E-RAD series of wrenches so there is little draw back in capability.
One aspect that is overlooked often with battery tools is that even though these tools have seen major advancements in the past few years, is is still limited by battery capacity. You can always add extra batteries to increase your work flow but for heavy duty continuous torque applications, a pneumatic or electric torque wrench would be a more suitable option due to the heavy workload.
Advantages and disadvantages of the hydraulic torque tool
The hydraulic torque wrench is a vital tool for the construction, engineering, and manufacturing industries. Its key advantage lies in its ability to deliver precise torque settings which are essential for proper assembly. Furthermore, this device exerts tremendous power compared to traditional wrenches yet produces a minimal amount of noise while in use. The hydraulic wrench has been the work horse for the industrial bolting industry as many of these tools are built to last! We currently have tools still in operation with over 25+ years of field use.
Yet, while it is a very dependable option people are preferring the speed and more of a hassle free experience with the gearbox driven tools. There are times where the hydraulic hoses, hydraulic pump, power supplies and the men needed to operate the job safely cane become cumbersome and at times dangerous due to all the moving parts. Where as of now hydraulic wrenches are mosed currently used is for extreme low clearance applications where it is difficult to fit any type of tool. The power of the hydraulic driven pump combined with the wrench often becomes the perfect if not the only solution to get the jobe done.
Although there are advantages and disadvantages associated with using a hydraulic torque wrench, on balance it has proven itself to be an effective tool for manufacturers who demand powerful and accurate results.
Tips for safely using a torque wrench
Torque wrenches are one of the most important tools a mechanic can have, but they must be used properly in order to function effectively and safely. To ensure maximum safety when using torque wrenches, you should always ensure that your wrench is properly calibrated prior to completing any jobs.
Conclusion
In conclusion, torque wrenches are invaluable tools that can make tightening and loosening fasteners simple and accurate. Electric, pneumatic, battery and hydraulic torque wrenches all have advantages and disadvantages that should be taken into consideration when deciding which one is best for the job.
No matter what type of torque wrench you use, it’s important to remember that these tools are designed specifically for specific tasks. Always read the instructions carefully and be sure to use the correct tool for each job.
By taking all of these things into account, using a torque wrench properly will eliminate guesswork from tightening and loosening fasteners while ensuring an optimal result each time.
