Power Multipliers

Pneumatic Torque Wrenches, PneutorqueHand 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 +1%.

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).



Pneutorque PTM-52 Series

PTM-52 Series PneutorqueThe PTM-52 is engineered to be one of the lightest and fastest tools of its type on the market. The exceptionally compact 52mm diameter gearbox means that the tool is well balanced, light weight and provides excellent access to bolts. Fast - 800 N·m version has a free speed of 175 rpm for rapid bolt run-down.

  • Light weight - single direction stall tool weighs just 3.8 kg.
  • Quiet - less than 85 dB(A) when under load.
  • Low vibration levels make these tools comfortable and safe to use - non impacting.
  • Square drive is quickly and easily replaceable.
  • 'Soft Start' trigger control aids socket location and allows gradual and safe reaction location.
  • For safety, gearbox can rotate independently from the handle so that reaction forces are not transmitted back to the operator.

Pneutorque PTM-72 Series

PTM-72 Series Pneumatic MultiplierPTM-72 tools use the same 'twin motor' handle as the PTM-52 but fitted with a durable 72mm gearbox to allow higher torque outputs. The 'twin motor' concept gives the benefit of high run-down speeds while adding very little to the size and weight of the tool.

  • Fast - 1000 N·m version has a free speed of 140 rpm for rapid bolt run-down.
  • Light weight - single direction 2000 N·m stall tool weighs just 6.2 kg.
  • Less than 85 dB(A) when under load.
  • Non impacting - low vibration levels make these tools comfortable and safe to use.
  • Quick and easy to replace the square drive.
  • Socket location is aided by the 'Soft Start' trigger control and allows gradual and safe reaction location.
  • Gearbox can rotate independently from the handle for safety, so that reaction forces are not transmitted back to the operator
  • Product Video.

Bi-Directional models can also be supplied as Shut-Off versions, with either Internal or External control, with miminum impact on the overall tool size and weight, meaning that a repeatability of +/-2% can be guaranteed.

Offsets

Geared Offsets for Norbar Pneumatic MultipliersOriginally designed to tighten plate heat exchangers where nuts have to rundown studs up to 1 metre.

Offsets are invaluable in situations where access is limited due to headroom or tool diameter.

The Geared Offset has been developed to enable the tightening of fasteners in environments where access restrictions prevent the use of a standard multiplier or where excessive stud lengths prevent the tighening of a nut with standard sockets.

Each geared offset is manufactured to customers specifications and is therefore tailor-made to their application. For this reason it is essential that we obtain as much information as possible.



Lifting Assemblies

Lifting Assemblies for Norbar Pneutorque MultipliersA variety of lifting assemblies have been developed to ensure that Pneutorques and Electrotorques can be manoeuvred and operated safely in a production environment.

Standard Series Pneutorques and Electrotorques with a capacity exceeding 9500 N·m are fitted with lifting brackets as standard. These tools are best handled with mechanical assistance.

For applications that require the smaller tools to be suspended by the use of a hoist or counterbalance, Norbar can supply a special purpose lifting bracket.

72mm Series Pneutorques and Electrotorques are all supplied with a lifting handle as standard. This handle is for manual use only and has no provision for alternative mounting such as a hoist or counterbalance.

For applications that require the tool to be suspended using a hoist or counterbalance Norbar can supply a special purpose lifting handle.

Customers requiring lifting handles for tools fitted with and Annular Transducer will require the longer Auto Two Speed versions.
