The swinging of the payload is one of the most important contributors to the dynamic loading of cranes. Faster transport of the payload brings up increased swinging, larger dynamic forces, and bigger control issues. That is the reason which makes the investigation of this phenomenon an increasingly actual theme. In the paper, the horizontal inertial forces imparted by the load in the case of the linear motion of the pivot are studied by means of an appropriate mathematical model. The diagram of the factor of the horizontal inertial forces of a swinging payload mass for different conditions of operation is determined. The developed curves are compared with standard curves. It is found out that in some of the cases the standard curves are not conservative.
