The operational reliability analysis of machinery: A case study of forest forwarders and their technological equipment

Abstract

Analysis and risk assessment are procedures which help to improve knowledge and are very important in practice. Risk assessment is possible to conduct only on the basis of exact accurate and tested information about the given system, which truly defines the given system within the spatial–temporal context. High standards of maintenance and treatment are closely linked with the requirements for quality and reliability forestry machinery and technological equipment. These standards are closely related to the maintenance of the equipment. This manuscript is focused on the reliability of standard forest machines used in the Slovak forestry. They are relatively modern and useful in the process of transporting and handling trees. This research showed the possibility of decreasing the production costs related to the maintenance of the devices and how to increase the final profit. The results of the research showed that the analysis of reliability is significant regarding to the quality of performed maintenance and the costs paid for it.
