Low vibration levels
25 January 2013
Recent tests by the HSE have shown that vibration exposure for operators using pneumatic torque multipliers to tighten 100 commercial vehicle wheel nuts was 10 times lower than when traditional impact wrenches are used.

Recent tests by the HSE have shown
that vibration exposure for operators
using pneumatic torque multipliers
to tighten 100 commercial vehicle
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 lab and
field tests by the HSE and both tools
confirmed manufacturer claims of
low vibration emissions.
The Control of Vibrations at Work Regulations impose a Daily Exposure Action Value of 2.5 m/s2, above which employers must introduce controls to eliminate or reduce exposure and provide health surveillance to those regularly exposed to vibration that exceeds this level.
The Pneutorque pneumatic torque multiplier does not exceed 2.5 m/s2., so there is no restriction in its use during the working day.
