The evaluation methodology operating status of cranes
Sedláčková, Martina ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The main theme of this bachelor's thesis is to design a procedure for the evaluation of the operating status of warehouse and workshop cranes. This methodology was tested in practice. This document also contains an overwiew of the main security risks arising form the poor condition of cranes, as well as an overwiew of places where defects on crane occur most frequently. The annex also contains photographs form the practical part.
