This paper analyses the economic feasibility of production and use of the new generation crane cabins of considerably lighter weight and stiff structure whose interior space necessary for the operator will be developed by using the methods of physical, cognitive and organizational ergonomics with the solved problem of visibility and which will allow higher productivity due to reduction of physical and psychologi­cal stress of the operator, as well as greater safety and security due to the integrated visual system. It is proved that the total economic benefit of the exploitation of the cabin in the overall exploitation period is significantly higher than the purchase price of the cabin, as well as that the internal rate of return is above the relevant average weighted interest rate and the payback period is less than three years. The analysed project of production and use of crane cabins with integrated visual systems for the detection and interpretation of environment is the project with low economic risk.
