Aviation maintenace crane
Bureš, Martin ; Šťastný, Antonín (referee) ; Pokorný, Přemysl (advisor)
This master´s thesis solves design of a mobile crane for handling air aggregates and ejection seats. Handling crane provides lifting a maximum weight of 300 kg to a height of 4600 mm. Subject of the work is the choice of appropriate technical solutions, design of lifting mechanisms, supporting structures and accessories. The suitability of the solution is checked by strength analysis of individual units. Another task is to provide mobility equipment and control stability against overturning. The appendix includes protocols static analysis of the program Nexis32, drawing overall crane assembly and manufacturing drawings selected parts.
