SYSTEM TO PREVENT COLLISION OF HOISTING CRANES Russian patent published in 2010 - IPC B66C13/18 B66C23/88 B66C15/00 

FIELD: transport.

SUBSTANCE: proposed system relates to construction equipment and can be used to prevent collision of hoisting cranes. Proposed system comprises data exchange hardware mounted on every crane, crane spatial position transducers and digital computer. The latter receives and processes output signals of transducers and data exchange hardware and to generate warning and/or interlocking signal, depending upon data processing results, when the crane approaches the other crane or stationary obstacle that have coordinates or parametres entered into digital computer memory. Digital computers allow data exchange with the help of data exchange hardware and using said data for signal processing and generating warning or interlocking signals. Wireless data exchange hardware can use ultrasound, and/or optical, and/or electromagnetic radiation and can determine the distance between said hardware components from time said radiation passes there between.

EFFECT: expanded operating performances, higher safety.
