Analysis of Anthropometric Compatibility of Tractor Driving Cabs
Anthropometry is a part of ergonomy responsible for measuring human body in its totality and components. The design of every handmade good concerning working sphere (but not only), needs the information supplied by this science.
In agriculture sector, anthropometry has a remarkable relevance above all in designing and realization of a tractor cab. This is due to the fact that workers spend the most part of day driving tractors. A tractor with an uncomfortable driving cab represents a risk for the driver. A space too narrow is extremely dangerous in case of overturning, collision with the inner side of the cab, unintentional use of a control and consequent accidental movement of the tractor. The present work is focused on experimental analysis of the inner dimension of tractor driving cabs. The main goal is to verify the respect of “the least overall dimensions” of the driver and, according to UNI EN ISO 3411 standard, is calculated on big size drivers; it corresponds to the inner surface of the cab with no visible deformation .The experimentation has been realized on 15 tractors of different dimensions and year of production. The results have been then compared to verify the least overall dimensions inside the driving cab. On the basis of the results, the analysis shows that all the tractors don’t respect some parameter of the standard.
