In this work both the theoretical and experimental models of the laboratory model of a truck crane are presented. The models consist of a telescopic boom, a hydraulic cylinder (changing the crane radius), rotational platform and a frame construction, which replaced chassis. An experimental and theoretical dynamic analysis of the truck crane is presented. Frequencies and corresponding modes of the system vibrations are determined. Transverse vibrations of the system (in boom’s lifting plane) are considered in the analysis. For the theoretical model four chosen frequencies and modes are identified. The results of the theoretical solution represented by the frequencies and modes are compared with those from the experiment. The relative error has been used as the criterion of the frequencies comparison. The modal assurance criterion (MAC) has been used to evaluate the agreement of the vibration modes.
