The Norbar HTX/X Handtorque® Standard Multipliers with AWUR can be used to increase the amount of torque applied to a bolt using a torque wrench. They provide an ergonomic solution to performing high-torque applications in areas with limited access. These multipliers feature the same accuracy (±4%) but differ in regards to their torque multiplication ratios, torque ranges, and the size of their input and output squares. For further information regarding these models, please see the following table.

The Norbar HTX/X Handtorque® Standard Multipliers utilise multiple stages of epicyclic gearing to generate greater output torques from the torque inputted via the torque wrench. This allows the operator to use a smaller torque wrench for high-torque applications. Additionally, each of the eleven models listed above features an anti-wind-up ratchet (AWUR) specifically designed to contain the forces generated during tightening. This improves both the safety and ease-of-operation of these instruments. For a quick introduction into how the AWUR operates, please see the following video.
The Norbar HTX/X Handtorque® Standard Multipliers can also be fitted with reactions of various styles (NOT included) to accommodate a majority of applications (please call for details).
Further to this, the Norbar HTX/X Handtorque® Standard Multipliers are compatible with Norbar’s electronic torque transducers. When fitted with an electronic torque transducer (NOT included), the Norbar HTX/X Handtorque® Standard Multipliers can be used to monitor torque precisely. For further information regarding compatible electronic torque transducers, please contact our sales team.
Finally, it is possible to order the Norbar HTX/X Handtorque® Standard Multipliers with a UKAS calibration. Again, please call for details.
The Norbar HTX/X Handtorque® Standard Multipliers with AWUR are versatile, precise and ergonomic. They are ideal for performing high-torque applications in cramped and/or difficult-to-access areas.
