Annotation:

The solution of differential equalization, describing the forced transversal vibrations of ropes of load-transporting devices bearing the mobile distributed and concentrated inertial load has been found. Formulas have been got for determination of amplitudes of the forced transversal vibrations of ropes depending on the velocity of movement and correlation between own and forced frequency of vibrations. The forms of the forced and forced “accompanying” vibrations have been built at the different velocities of movement of ropes and different values of frequency of forcing influence.
