FIELD: construction industry.
SUBSTANCE: invention refers to safety and control systems of travelling hoisting cranes and cranes with movable equipment. Safety system includes digital unit, to data inputs of which there connected are crane parametre sensors containing at least one movement sensor, actuating unit connected to outputs of digital unit, and at least one indicator. The latter is connected to digital unit and made with possibility of generating signals depending on its current spatial position relative to control position, and digital unit is meant for correction of movement sensor readings as to signals supplied from indicator by using coordinates of control position, which are recorded in digital unit. In addition, safety system is equipped at least with one device installed in control position in working area of movement of crane and/or crane equipment and made in the form of active or passive transponder, or metal flag, or rack, or another metal device so that it interacts with indicator.
EFFECT: simplifying maintenance of crane with safety system, as well as enlarging application area of safety system due to control of positions not only of crane mechanisms, but also crane itself.
