Pneutorque® Pneumatic Multipliers
What is a Pneutorque Pneumatic Wrench?
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.
Air pressure graph supplied with each tool.
The Lubro Control Unit, 16074, is Norbar’s filter / regulator / lubricator. It is
supplied with 3m of high quality steel braided air hose and a 100mm pressure
gauge for accurate setting.
Why use Pneutorque Pneumatic Wrenches?
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%.
Summary of Pneutorque Advantages
• Sound pressure level does not exceed 85dB(A) when tested in accordance with
ISO3744:1994.
• No impacting means less damage to the tool, socket and bolted assembly.
• Less operator fatigue, results in increased safety.
• Powerful – models available up to 300,000 N.m (220,000 lbf.ft).
• Repeatability of ±5% for accurate torque control.
• A wide range of attachments and accessories make Pneutorques adaptable to
many applications.

Pneutorque Applications
The smooth and continuous torque output of the Pneutorque makes these tools
suitable for a wide range of bolting and non-bolting applications.
Bolting
Pneutorques are ideally suitable for tightening and untightening bolts of up to
150mm diameter.The following is just a small selection of applications:
•
•
•
•
•
•
•
Wheel nuts on trucks, buses and large machinery.
Structural steelwork.
High pressure joints eg. Pipelines, boiler feed pumps and pressure vessels.
Engine head bolts.
Injector heads on plastic injection moulding machines.
Heat exchangers.
Heavy vehicle production eg. Chassis and suspension bolts.
Ball valve actuation using PT13
Non-bolting
Whenever a high continuous torque is needed, Pneutorques can be used as the
power source.Typical applications include:
•
•
•
•
•
•
Ball valve operation.
Powering wagons and gantries.
Barring of large diesel engines (turning the crankshaft) during build.
Weld testing by applying test torques.
Roller adjustment in steel mills and paper mills.
Valving of gas bottles.
Gas bottle valving and de-valving using PT1500

Pneutorque® PTM-52 Series
Stall Models
The 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.
PTM-52-800-B
• 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.
• Non impacting – low vibration levels make these tools
comfortable and safe to use.
• Square drive is quickly and easily replaceable.
• On Bi-directional tools, the direction control knob is locked while
the tool is running to prevent accidental damage to the gearbox.
• ‘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.
• 1” square drive available, Part No. 18545.

Pneutorque® PTM-52 Series
Internal Control and
External Control Models
The integration of electronic torque
measurement and control into the
PTM-52 Series is achieved with
the minimum impact on overall
tool size and weight. The actual
applied torque is accurately
measured at the output of the tool
meaning that a repeatability of +/-2%
can be guaranteed.
Shut-Off, Internal Control – these tools include a torque
transducer, easy to read LED display, control panel and a solenoid valve
to shut off the air supply once the desired torque has been reached.
The tolerance band within which the bolt must be tightened can be set
on the tool handle control panel. When the tool is operated, the actual
applied torque is displayed along with one of three coloured LEDs to
indicate a low, within tolerance or high result. The tool can be operated
in either N.m or lbf.ft.
Shut-Off, External Control – this version of the
PTM-52 incorporates a transducer, solenoid valve and three coloured
LEDs for the indication of low, within tolerance or high results.
However, all control functions and torque display are housed in an
external controller unit (purchased separately). External controllers can
give a much greater range of functionality than is possible on the
‘Internal Control’ version of the tool.

The TrukTorqueTM pneumatic torque multiplier features a special curved reaction arm
designed to handle bolt tightening on the front and rear wheels of trucks and buses.The
design easily accommodates wheel trims and deeply recessed wheel bolts.
TrukTorqueTM has none of the noise and vibration problems associated with impact
wrenches and can provide accurate torque control without the need to check every
wheel bolt with a manual torque wrench.
• Maximum torque of 1000 N.m (738 lbf.ft) covers all truck and buses.
• Free running speed of 140 rpm for rapid bolt rundown.
• The reaction socket is spring loaded to locate on the next available nut for
safe and secure reaction.
• Robust and lightweight.TrukTorque is
lighter than comparable impact
wrenches.
• Compatible with most trucks and bus
wheels.

72mm gearbox diameter allows excellent access.
Powerful – up to 2000 N.m output.
Switchable forward and reverse operation.
Quiet – less than 81dB(A), and non impacting for low
operator fatigue.
‘Soft Start’ trigger control aids socket location and allows
gradual and safe reaction take up.
For safety, gearbox can turn independently from the handle.
Torque reaction is never transmitted back to the operator.
All torques can be achieved at less than 6 bar (90 psi).
Automatic Two Speed models offer all of the advantages of
the single speed versions but with the additional benefit of a
run down speed five times greater than the final torque speed.
