Specifications Indications on whole-body vibration Whole-body vibration is less than 0.5 m/s² during correct machine operation Uncertainty of measurement K has been taken into account for the specified values. This section contains vibration indications and shows how to determine the vibration levels. The degree of vibration is influenced by various parameters. Some of them are listed below • User training, behaviour, working method and strain. • Work site: organization, preparation, surroundings, weather conditions and material. • Machine: version, seat quality, quality of suspension system, attachments and condition of attachments. Precise indications on the vibration degrees cannot be made for this machine. Determination of vibration level for the three vibration axes. ☞ Under typical operating conditions, use the average vibration values measured. ☞ In order to obtain the estimated vibration value for an experienced user on level ground, subtract the scenario factors from the average vibration value. ☞ In case of an aggressive working method or difficult terrain, add the environmental factors to the average vibration level in order to obtain the estimated vibration level.
Notice! All vibration values indicated in m/s². Note: For further vibration indications, refer to the indications in ISO/TR 25398 “Mechanical Vibration – Directive on Estimation of whole-body vibration when operating earth moving machines”. This publication uses measuring values of international institutes, organizations and manufacturers. It contains information on whole-body vibration for users in earth moving machines. For more information on the vibration values of the machine, refer to Directive 2002/44/EC of European Parliament and Coucil on minimum health and safety requirements regarding exposure of workers to risks arising from physical agents (vibration). The Wacker Neuson seat complies with the criteria established by the ISO 7096 standard. It explains the values for vertical vibration under heavy operating conditions. Guidelines regarding reduction of vibration values during operation of earth moving machines:
☞ Perform correct adjustments and maintenance work on the machine. ☞ Avoid jerky movements during machine operation. ☞ Keep slopes in a perfect condition.
