The pce vm 31 hawb human vibration meter is designed for measuring human vibration at the workplace. Mechanically isolate the vibrating source or surface to reduce exposure.
Evec Whole Body Vibration System
Whole body vibration measurement equipment. Large shocks and jolts may cause health risks including back pain. Limit the time spent by workers on a vibrating surface. Off road mining equipment operates on rough surfaces under harsh operating conditions that produce wbv and mechanical shock. Whole body vibration measurement. The initial phase of the research focussed on obtaining long duration measurements of whole body vibration during normal equipment operation. The vibration meter can calculate hand arm vibration measurements according to iso 5349 and whole body vibration measurements according to iso 2631.
Designed specifically for the measurement of whole body vibration and the vibration dose value. Sufficient whole body vibration measurements at underground coal mines to manage exposure to the hazard has previously been difficult because of the complexity expense and relative fragility of the measurement equipment. Exposure to whole body vibration wbv negatively impacts the health and safety of exposed mine workers. Human exposure to whole body vibrations should be evaluated using the method defined in iso 2631 11997. Whole body vibration generally results from plant operators such as earth moving equipment truck drivers airplane helicopter pilots crane and train drivers and the like whereby their whole body oscillates up and down side to side and or back to front or a combination of these. Simultaneous 3 channel measurements of the x y and z vibration levels plus the vector sum using the relevant weighting curves.
Whole body vibration measurements equipment and procedure. Consequently relatively few measurements of whole body vibration are routinely undertaken at underground coal mines. Measurements were obtained using an ios application wbv v22. The following precautions help to reduce whole body vibration exposure. Install vibration damping seats. Whole body vibration wbv is transmitted through the seat or feet of employees who drive mobile machines or other work vehicles over rough and uneven surfaces as a main part of their job.
Drivers of some mobile machines including tractors fork lift trucks and quarrying or earth. Who can suffer from whole body vibration. Whole body vibration is applicable to motions transmitted from workplace machines and vehicles to the human body through a supporting surface. Whole body vibration what is whole body vibration. Vibration is often complex contains many frequencies occurs in several directions and changes over time. Front end wheel loaders along with haul trucks show the highest number of injuries related to jarringjolting and whole body vibration.
Ensure that equipment is well maintained to avoid excessive vibration. Negative health effects of exposure to whole body vibration are prevalent in the industrial world today particularly where heavy earth moving equipment and off road vehicles are necessities. For health and safety evaluations this is through the buttocks and feet of a seated person or the feet of a.
