Hand operated torque multipliers are ideal for low volume or intermittent use or when there is no power source available. However, for production lines or whenever a large number of bolts is involved, a powered multiplier will save a considerable amount of time.
PneuTorque operation is quiet - less than 85dB(A) 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%. 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.
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.
Models are available up to 300,000 N·m (220,000 lbf·ft).
The 'Standard Series' PneuTorque is a direct result of over 50 years of refinement and development necessary to keep pace with the requirements of industry today.
Two Speed models offer all the advantages of single speed version but with the additional benefit of a run-down speed five times greater than the final torque speed.
Models available up to 300,000 N·m.
These PneuTorque models share the same features as the standard series whilst offering a higher torque output for a given gearbox diameter.
Torque output up to 5500 N·m and can be used for tightening and untightening. Electronic Torque Transducers can be fitted for precise torque monitoring.
The PTM series of PneuTorques is engineered to be amongst the lightest and fastest on the market for torques up to 6000 N·m. Torque control is normally achieved by adjustment of air pressure. An air pressure versus torque graph a calibration certificate is supplied with each tool.
PTM-52, PTM-72 and PTME-72 also offer the option of electronic torque control.
The PTS is the result of an extensive design project to produce an efficient air motor, purpose built for this application in an accurate torque tool. The new air motor is then married to Norbar's respected gearbox range, sharing common torque reaction accessories with PTM and EvoTorque® tools.
