Abstract

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 analyzed 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.

Highlights

As a result of the complicated and constantly changing nature of industrial and construction work, there are very high injury and fatality rates, where cranes contribute to as many as one-third of all fatalities and injuries resulting in permanent disability [01]
For the assessment of the economic feasibility of the new generation crane cabin purchase, we used the data referring to the bridge crane cabin
Table 1. provides the estimated data and, by using equtions from (1) to (7), calculated values referring to the costs of purchase and savings during the exploitation of the new crane cabin

Summary

Introduction

As a result of the complicated and constantly changing nature of industrial and construction work, there are very high injury and fatality rates, where cranes contribute to as many as one-third of all fatalities and injuries resulting in permanent disability [01]. The second approach refers to an assessment of economic feasibility of investing into acquisition of a new generation of crane cabins and/or comparison of such investments (initial investment costs) and discounted additional effects (savings) in the crane exploitation over the entire (remaining) lifetime.
