Description
Summary:The use and operation of crawler cranes in the Czech Republic is dependent on the availability of several major producers (Liebherr, Caterpillar, Volvo, Sennebogen, etc.) and Czech producers (Unex Uničov with its successor ND LOR Uničov, Tatra and others). The authors of this article explain the problems of operation, repairs and risks of failures in specific types of crawler cranes supplied by Liebherr during their operation in the steelmaking company Třinecké železárny, a.s. and Trilet Ground Services, a.s., the company specialized in renting machines that are used for foundations of buildings. The article proceeds from the evaluation of the operational data of both delivered and repaired machines and the data obtained from the repair company needed for the commissioning of the serviced machine, as well as the frequency of repairs during the specified hours of work within the course of operation of the machines. The processed data serves as a basis for the evaluation of risk of possible failures when using machines. Risks are evaluated using the FMEA method.
