Many procedures in the development process of crane cabins today are still based on the specific experience
of manufacturers and historical guidelines. It is not surprising that they fail to meet the needs of a
large proportion of operators. Accordingly, the need for more objective, theoretically justified and consistent
models, that will minimize crane operators’ biomechanical and visual problems through anthropometric
characteristic analysis to improve safety and prevent crane related fatalities and injuries, arises. In
that aim we firstly identified the critical characteristics of existing crane cabins linked to visibility and
posture (seat and armrest problems) using users’ opinions and Pareto analysis. We then collected rarely
available data on crane operators in Serbian companies (64 in the first and 10 operators in the control
sample) and proposed methodology for the ergonomic assessment of crane cabins based on drawing-board
mannequins and kinematic modeling. The implemented methodology interval estimate obtains
an interior space of 1095 1150 1865 mm in which is possible to eliminate the critical characteristics
of existing crane cabins. The research results fulfill user needs not satisfied in existing crane cabins and
suggest certain changes to existing standards on the path to improved safety.
