Abstract
When the trajectory of the movement of the mechanized complex changes before its complete reversal, a wave-like change in loads on various sections of the support occurs. The analysis of the data obtained as a result of experimental studies made it possible to identify a number of patterns that cause periods of increasing and falling loads at various stages of changes in the trajectory of the complex.
