FIELD: materials handling equipment. SUBSTANCE: system has a supply unit, ROM module, microprocessor controller, indication and data input modules. It also has real time module, operating mechanism control commands coder and decoder, operator's code input device and its personal data storage device which is made in the form of special tag with electrically intercoupled memory element and disconnector. Proposed design of system males it possible to preclude access of unauthorized personnel to crane controls, ensure against breakdowns caused by incorrect control and operation of cranes and find easily those who are responsible for emergency situations. EFFECT: improved reliability and safety. 3 cl, 1 dwg
