This paper examines irregular malicious effects on cranes that cause extreme dynamic phenomena. An experimental investigation of forced swinging of bridge cranes is first conducted, followed by a numerical simulation. The authors observe the case of forced vibrations of the crane body with synchronous harmonic excitation, caused by the physical action of a group of people. The presented theoretical analysis is used for checking the sensitivity of large flexible structures at risk from malicious acts. Analyses are used to extract critical frequencies of malicious actions. The novelty of the paper lies in the mathematical modeling of dynamic excitation caused by synchronous jumping of people.
