POWERED TORQUE TOOLS POWERED TORQUE TOOLS Electronic Tools EvoTorque® are electronic torque tools designed for applying torque to threaded fasteners. The unique ‘Intelligent Joint Sensing’ technology will accurately tighten to the correct torque without the risk of excess overshoot or undershoot that is common in other electric tools. EvoTorque® tools give continuous (not impacting) rotation and are quiet in use. EvoTorque® tools utilise patented technology to give unprecedented joint control from hard through to soft joints. They are available in both mains-electric and battery-powered ranges. On a given joint they will consistently achieve accurate, repeatable results of ±3% of the setting within the calibrated range. Pneumatic Tools PneuTorque® operation is quiet with absolutely no impacting. These two factors make PneuTorques comfortable for the operator to use, reducing fatigue and consequently increasing safety. PneuTorques provide accurate torque control – on a given joint they will stall repeatably to within ±5% (PTS tools, ±3%). Using electronic shut off, this repeatability can be improved to ±2%. The PneuTorque® consists of a robust air motor driving a Norbar multiplier with three or more stages of epicyclic gearing. This gives the advantage of smooth, continuous rotation (versus an impulsing action or the hammer action in an impacting tool). The benefits include : • more consistent bolting, • less damage to bolt, socket and joint, and • reduced operator injury & fatigue. Torque control is achieved by adjustment of the air pressure. An air pressure versus torque graph and a calibration certificate are both supplied with each tool and allows specific torque values to be set. For more critical applications, PneuTorques can be fitted with a torque transducer and the precise torque output displayed. The tool can then be shut off at the desired torque either manually or automatically using suitable control circuitry. Models are available up to 300,000 N � m (220,000 lbf � ft). enquiry@norbar.com | www.norbar.com 2
