FIELD: mining.
SUBSTANCE: invention is related to machine building support of mining industry, namely as combination of processes in servicing of excavators and roller-bit drilling machines designed for production of minerals by open-cut method. Method for lifting of heavy quarry equipment modules, in which lifting force is developed by power hydraulic cylinders, at the same time energy of high pressure working fluid is used, during the whole process of lifting, possibility is provided for automatic blocking of hydraulic system elements failures. Besides power hydraulic cylinders are equipped with parallel-acting screw jacks, the latter are used, at the moments of modules lifting, to set possibility of synchronous motion with power hydraulic cylinders without formation of lifting force, and at the moments of lifted modules slanting, to provide for the possibility of its leveling.
EFFECT: broader field of application, increased reliability, making process of modules lifting independent.
