Abstract

The article presents the results of the investigation into the effect of dry friction forces on the magnitude of the dynamic load acting on the rope in the process of safety braking. The equations for the analysis of the process of safety braking are presented. The analysis of the process of changing the forces in the rope showed that the maximum forces in the rope arising in the lifting mode of the load can be reduced by a factor of three of the forces of natural resistance to movement of the vessel. Modeled of sudden exertion of the brake force to the brake drum in the lifting mode. The results of mathematical modeling, presented in the form of graphs of changing efforts in the rope, confirm the theoretical results. The data obtained allows getting an expression for calculating the braking force, applied to the lifting container to eliminate head ropes during of safety braking.
