Today most space rockets are lifted into vertical position in partially or fully assembled form using the lifting mechanisms constructed primarily on the basis of the multi-stage hydraulic cylinders. At the same time, selecting rational parameters for such mechanisms is a rather difficult task due to complexity of the dependencies describing their operation. The paper proposes dependencies improved in comparison with the known methodologies to determine the hydraulic cylinders optimal installation angles in the initial position, as they are more convenient in the corresponding computation. An algorithm is provided to select the working diameters of the hydraulic cylinder stages and rods with rounding the obtained values and taking into account, for example, size ranges of the commercially produced seals and support rings. Certain criteria for selecting the most rational combinations of parameters for the lifting drives are presented, as well as the improved methodology for choosing parameters of the lifting mechanisms developed with their use.
