while further investigations should be made in order to test noise, vibrations, luminance, temperature and air humidity. Controls also give sufficient room for future research. There is also a need for extensive surveys focusing on both male and female crane operators in different regions in order to generate region specific anthropometric databases for the further safe and efficient design/modification of crane cabins with harmonizing
all collected data. The percentiles are univariate (one-dimensional) statistics applied to multivariate situations, so future research could also deal with that fact and apply multivariate statistics.
