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
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.
