Tests carried out by the HSE have
demonstrated that vibration
exposure for operators using
pneumatic torque multipliers to
tighten wheel nuts was 10 times
lower than when traditional impact
wrenches are used. The Norbar
Tests carried out by the HSE have
demonstrated that vibration
exposure for operators using
pneumatic torque multipliers to
tighten wheel nuts was 10 times
lower than when traditional impact
wrenches are used. The Norbar
Pneutorque PTM-72-1350B and one
other multiplier were subjected to
the tests and both tools confirmed
manufacturer claims of low vibration
emissions.
Low vibration levels help to avoid
risks such as Vibration White Finger
(VWF). The Norbar Pneutorque
pneumatic torque multiplier does
not exceed 2.5 m/s2 so no daily
restrictions on its use are required.
In addition the torque multipliers
are quieter in use so exposure time
can be safely increased without the
compulsory use of ear defenders. A
typical impact wrench will reach 90-
98dBA when idling and exceed this
level when impacting, the Norbar
Pneutorque reaches only 83dBA.
