This study formulates and solves the problem of transverse damped vibrations in a crane boom of a truck-mounted crane. Dissipation of vibration energy in the model adopted results from motion resistance in slides between the moving components of the crane boom. A damping using Kelvin-Voigt model that characterizes dynamic properties of slides was added to the system. The effect of changes in damping coefficient and rigidity of springs on eigenvalues of the system studied was presented. The damped vibration frequencies and the degree of amplitude decay were calculated.
