Biomechanical approach to improving safety of working conditions at non-stationary workplaces in railway transport (on the example of the workplace of train components)

Abstract

The article thoroughly examines the work activities of train compilers working in non-stationary workplaces within the railway transport system, the ergonomic safety conditions, and the impact of professional factors. In particular, the actions of train compilers related to the stairs and railcar handles, static and dynamic loads, and the anthropometric and biomechanical inconveniences they encounter during the work process were analyzed. In accordance with the current standards OST 24.050.67-87 and GOST 12.2.049-80, the design shortcomings of wagon handles, in particular, ergonomic inconveniences during reliable hand gripping, and shortcomings in protection against slippage and thermal effects, have been substantiated. Based on the research results, the need to redesign the handles based on ergonomic biomechanics requirements to ensure safe and efficient work for train assemblers has been substantiated.
