Abstract The purpose of this study was to estimate vibration levels at the work posts of compact construction machine operators and to comply with the requirements of standards for seat and vehicle test codes. Vibration levels were measured at 15 operator's posts, helping to assess the effectiveness of seat suspension. Most of the compact machines tested produced relatively severe fore-and-aft low-frequency vibration, although the size of this vibration depended on the type of work in progress and the operator's driving style. Only loaders and site dumpers seemed to be subject to strong vertical vibration. These machines are often equipped with compact vertical suspension seats which are quite effective at reducing vertical vibration. The results suggest that seats that successfully pass the INRS class I test for seats of forklift trucks with a load capacity of less than 5 tonnes are suitable for reducing vertical vibration on compact construction machines. In the case of compact site dumpers it is preferable to use the type of seat designed for agricultural tractors with a load capacity of less than 3.6 tonnes. There are no compact seats with fore-and-aft suspension, however. Development work is required here before any tests codes can be proposed.
