Scope

This Technical Report provides guidelines for those such as employers, national authorities and manufacturers of earth-moving machinery who are required to determine, assess and document the daily whole-body vibration exposure for ride-on machines as defined in ISO 6165. It also provides guidelines for reducing vibration levels on machines and for determining the vibration reduction from machine improvements to reduce vibration levels. It is intended to assist in establishing documentation for specific earth-moving machinery under typical operating conditions. It gives guidance on determining the daily vibration exposure A(8), in accordance with ISO 2631 and EN 14253, offering a simple method for determining the daily vibration exposure by means of a table which indicates the daily exposure as a function of the equivalent vibration total value and the associated exposure duration. Both methods can be used even in cases of multiple exposures on the same day. Methods are provided for calculating exposure using reported emission values, valid for machines equipped with a seat in accordance to ISO 7096. NOTE Additional information is given in the EN 474 and EN 500 series of standards. Workplace measurements are required where suitable data are unavailable to represent the vibration under the specific working conditions, or if the calculation results are not useful for determining whether or not the vibration exposure limit value or exposure action value is likely to be exceeded. It is important that the vibration values used in the exposure assessment are representative of those in the specific use of the machines. This Technical Report does not deal with assessments of exposure to shock. NOTE The guidelines for determining, assessing and documenting the daily vibration exposure from use of ride-on operated earth-moving machinery also cover the requirements of the European Physical Agents Directive (Vibration) 2002/44/EC.
