Norbar Launch New Torque Multiplier

Norbar Torque Tools is proud to announce the launch of its Pneutorque® PTM-92-4000, a powered torque multiplier ideal for the open cast mining industry where large haul trucks are used. The PTM-92-4000 replaces Norbar’s PTM-92-3500 in the existing PTM-92 series. The new multiplier offers an increase in torque output from the 92mm gearbox, made possible with a new output carrier manufactured from a high strength, specialist steel. The update comes as part of Norbar’s on-going policy of continual improvement. Philip Brodey, Sales and Marketing Director at Norbar, said: “This update will enable us to put an even better product out on the market for our customers – especially for those maintaining mining haul trucks where large numbers of bolts need tightening.” “The improved offering demonstrates our commitment as a company to continually provide the very best torque tooling products to the marketplace.” Pneutorque operation is extremely quiet - less than 85dB (A) - with absolutely no impacting, making them comfortable for the operator to use, reducing fatigue and consequently increasing safety. The Pneutorque PTM-92-4000, like other Pneutorques, consists of a robust air motor driving a Norbar multiplier with three or more stages of epicyclic gearing. Torque control is achieved by adjustment of the air pressure. An air pressure versus torque graph and a calibration certificate is 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.
