The goal of research is to investigate rolamite motion supports, their dynamics, to prove possibility of above mentioned mechanism to be controlled precisely and ability to use in everyday practice in field of lifting technics. The object of investigation is rolamite type mechanism, movement of which is controlled by vibrations. As the result of investigation, it was found, that vibration controlled rolamite type motion supports assures smooth, quick and accurate movement of working parts. It is possible to create conditions, which can assure movement of assembly parts with no slipping and no gap between them. It means, that such a mechanisms have the unique precision, which is not possible, using other mechanical drive constructions. Such a precise mechanisms are on demand in most branches of industry. While investigation took place, author tried to find possibilities to use such a mechanisms in lifting technics. It was seen, that these mechanisms are able to use in some assemblies, used in lifts and hoists. Especially interesting is possibility to make vibration controlled brake mechanisms for braking the ropes and sliding block-stops. In this case it is possible to create the self controlling system to prevent lifted weights from falling in case of failure in the electrical mains system. It would be excellent decision for changing the basic system of lifts and winches, used nowadays. These mechanisms will assure security, that still was not reached in nowadays technics.
