Abstract
The paper considers the influence of the main design parameters of the front-end equipment of mining shovels - outreach and bucket capacity for dynamic component of the drive load lifting. The dynamic equivalent circuit of the cable-sheave block system, the expressions to determine the stiffness of the system, made and agreed differential equation of motion, determine the range of natural frequencies of the system, the amplitude-frequency response of the gain of the external load on the length of the boom and bucket capacity.
