There is now a vast range of torque wrenches widely available on the market as each application has a specific tool suited to the requirement. Whether it’s access to the bolt, size of the bolt, amount of torque required, to name a few areas of consideration, it is vital that Technicians use the correct tool for the job.
As safety precautions have increased and operator safety become a considerable part of the industry requirements, new technologies have progressed. Advancing the usability of torque wrenches for both functions, making them lightweight, and durable, increasing their value over the tool’s lifetime.
The progression of engineering from hydraulic torque wrenches to intelligent electric torque wrenches has provided users with the ability to track and record data more efficiently. Electric torque wrenches have become the popular choice within industries, such as manufacturing, aerospace, renewables, and oil and gas. Electric versions on torque wrenches offer great accuracy than pneumatic torque wrenches. For example, the Norbar EvoTorque® 2 has unique intelligent joint sensing technology that continuously measures the joint during tightening and, when necessary, employs dynamic braking to avoid torque over-shoot due to motor inertia.
Electric torque wrenches, such as the EvoTorque® 2 from Norbar, are great tools when repeatability and traceability are required. Although they need a large access area around bolts, due to their design, they can provide torque accurately over a wide range of joints and provide ID tags and readings to ensure the correct torque is applied to each bolt.
Electric torque wrenches can be seen as a cost-effective alternative to Hydraulic versions. They don’t require a separate pump to power the tool, only access to a 110 or 230-volt power supply, saving users money on purchasing a separate hydraulic power pack.
Users can sometimes spend less money on repairs and servicing as well, as they are less prone to wear and tear due to there being no hydraulic components. Although Electric Torque Wrenches are more expensive to purchase from new, and should an electrical error occur, they require more significant maintenance costs, especially if they are intelligent torque wrenches with digital capabilities.
The HTL Group is dedicated to supporting various industries with the latest digital innovations on the market, which is why we offer Norbar’s range of torque wrenches, alongside industry-leading hydraulic torque wrenches.
