Abstract

When designing new and/or modifying pre-existing equipment, the problem of economic feasibility is always of prime importance . However, the economic feasibility is often a matter of discussion in various social aspect. To operate no aesthetic, noisy, dusty, gazed heavy machine with large number of visually fixed moving parts and gearing, it is often dangerous and even risky. The work productivity of such machines will always be reduced directly or indirectly because of psychological incompatibility of the workers and the machines or due to social damage related to often illnesses of workers or fluctuation of labors. The level of psychological and working compatibility of the operators of the machines in view of all modern requirements of ergonomics and design, are of second order effect.
