RR794 – Vibration measurements on torque multipliers

It was brought to HSE’s attention that torque multipliers were being used instead of impact wrenches in some instances in the workplace. Given that torque multipliers are purely rotary machines, the vibration level is likely to be much lower than that on an impact wrench. HSL had not previously measured the vibration magnitudes associated with the use of torque multipliers and so were asked by HSE to see whether they are a practicable alternative to impact wrenches and to investigate the differences in vibration exposure associated with their use.
