METHOD OF CONTROL AND REGISTRATION OF LOAD-LIFTING CRANE OPERATION Russian patent published in 2008 - IPC B66C23/88 B66C13/18 

FIELD: hoisting-and-transporting mechanical engineering.

SUBSTANCE: invention can used in the crane control and safety systems. Method consists in transfer of control signals from remote control board (RCB) located outside the crane using a two-way line of wireless communication, measuring the working parameters, converting measured sizes into digital signals, defining safe loads and limiting positions of the crane structural components and switching off its mechanisms on reaching limiting values, recording the crane operating and data signals and time of their arrival into long-term nonvolatile memory to be read out in case of need, and also their remote transfer to the dispatcher control located outside the crane. In addition, RCB outputs the instructions to transfer the crane data and control signals to be written down into RCB nonvolatile memory to be read out in case of need by transmitting the signals to the dispatcher control station, registration and storage of data on the crane operation. Here, note that two-way wireless communication lines are used to this end.

EFFECT: higher reliability of control and registration of crane working parameters.
