||The purpose of this study was to meet the need for noise and vibration standards at the fork-lift truck driver's station. A large number of vehicles were tested (81 were selected for acoustic environment testing and 77 for vibration testing) in order to cover the most commonly used types of machines in factories, ports and building sites. Analysis of noise exposure showed that drivers of thermally powered fork-lift trucks were likely to suffer hearing damage in case of intensive use. The study led to a new, simplified method for noise exposure evaluation which can be applied for labelling purposes of the trucks. Vibration measurements gave a picture of vibration exposure at the drivers' station and of the efficiency of seat suspension. Tested vertical seat suspensions frequently proved to be unsuitable. To avoid this situation and meet the requirements of European Directive 91/368/EEC (see CIS 89-1442 and CIS 92-25), a specific vibration test code for fork-lift trucks is proposed. Approximately 20 seats were tested in reference to the proposed standard; three proved efficient in reducing vibration levels on trucks with a capacity of five to ten tonnes, and eight on trucks with a capacity of less than five tonnes.
