FIELD: mechanical engineering; load-lifting facilities.
SUBSTANCE: invention relates to warning, emergency and control signaling of boom and bridge cranes, lifts and other load-lifting machines. Method is implemented by receiving data of value of at least one operating parameter, or conditions of load-lifting machine or its component, or control action of operator to charge said operating parameter or condition of load-lifting machine or its component. Provision is made for converting data into warning or control signal. In process of conversion of said data they are compared with preliminarily set or memorized limit value of operating parameter or condition of load-lifting machine or its component part, or value of control action of operator. If comparing reveals that data reach limit value or condition, intermediate signal is shaped. Then, depending on value of intermediate signal, warning or control signals are shaped.
EFFECT: improved safety of operation of load-lifting machine, including safety of operator and maintenance personnel.
