Comparing the Norbar EvoTorque vs. Pneutorque Torque Multiplier Series
Generating the needed torque when working with bolts in confined or isolated spaces can be difficult with a cheater bar or other conventional bolt tools.
Torque multipliers allow you to generate the force needed to ensure safe placement and removal of bolts in various applications. They work by giving users the leverage versus having the torque generated through the tool itself, which provides an extra level of safety and control.
Norbar is known for producing a number of quality torque multipliers, including their EvoTorque and Pneutorque series. What are the pros of each series, and how well could they handle the applications you deal with daily? We’ll go over the features offered by each, and why you might wish to choose one over the other.
EvoTorque Series
Both the EvoTorque and EvoTorque 2 torque multipliers use electricity to generate torque. They automatically sense how much tightness is needed for various bolts and shut off if it detects it’s about to apply more force than required, preventing users from making critical mistakes that end up costing time and money.
The EvoTorque 2 is capable of applying the correct amount of torque over a variety of hard and soft joint rates. It's capable of managing fluctuations in frequency variation and supply voltage while still running accurately. It doesn’t start when it senses the supply voltage being outside of normal tolerance.
Additional Features
- Memorizes multiple work targets
- Three different modes of operation: torque, torque and angle, and torque and audit
- Guaranteed accuracy of +-3%
- Backlit LCD display to ensure visibility in difficult conditions
- Contains key lock preventing unauthorized use
- Built to conform to IP44 standards when it comes to dust and water ingress
Best Uses
- Good for operators needing to integrate with different control systems
- When you need to work with both soft and hard joint assembly applications
- For accumulating statistics and data readouts over time
Pneutorque Series
The non-impacting quiet operation of Pneutorque torque multipliers makes them less fatiguing to the operator, which in turn improves worker safety. The tools are powered by an air motor, using air pressure to achieve the needed amount of torque control. Users receive a graph showing the air pressure versus torque along with a calibration certificate, which allows them to set specific torque values.
Pneutorque tools provide accuracy to within +-5% when electricity is on and +-2% when turned off. They also come with different accessories, making it easy to adapt the tool for use with different applications.
Additional Features
- Sound pressure never exceeds 85dB(A)
- Provides accurate torque control with repeatability of +-5%
- Available in models up to 300,000 N * m
- Comes with a variety of accessories
Best Uses
- Tightening and untightening bolts up to 150 mm in diameter
- Non-bolting operations requiring continuous torque
Final Summation
The EvoTorque series is geared towards those looking for a tool with more advanced technology features capable of providing immediate feedback for data analysis. They also work well on a range of applications with hard and soft joint assembly.
The PneuTorque series would work well for those needing to work with bolting and non-bolting operations. They can handle anything from structural steelwork to ball valve operation.
Consider the environment of your workers and the needs of the job when choosing between the two types of torque multipliers. Both tools provide operators with additional control when it comes to working on various applications in construction and mechanical repair.
