Course participants will learn the operating principle and operational characteristics of hydrostatic and hydrodynamic drives. They will be familiarized with the various control- and regulating methods of hydraulic drive systems. They will be familiarized with the components of hydrostatic drives: axial piston systems, pumps, motors, control elements, regulating elements, differential gears, auxiliary units. They will get an insight into the impeller drive, structural elements, structure, and operating principle of self-propelled machines. They will learn how to operate and maintain mobile equipment, and to search for system errors.
