METHOD OF AND DEVICE FOR SUPPLY OF MEASURING AND CONTROL COMPONENT PART OF LOAD-LIFTING CRANE SAFETY AND CONTROL SYSTEM ARRANGED ON BOOM OR ON TACKLE BLOCK Russian patent published in 2008 - IPC B66C13/18 B66C15/06 B66C23/88 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to safety and control systems of load lifting cranes. Proposed method of supply of measuring and control component part of safety and control system arranged on boom or tackle block of load-lifting crane comes to use of self-contained supply source with automatic charging the source from generator - converter of mechanical energy of moving load or boom wire rope of load-lifting crane or block directing or supporting the wire, rope, into electric energy. According to invention, said component part of safety and control system of crane provides measuring of at least one operating parameter and control of loads, particularly, marker light and/or headlight. To charge self-contained supply source, in additional of wire rope motion energy, use can be made of energy of external mechanical actions, solar energy or heat energy of surrounding medium. Transmission of data between component parts of system can be provided by wireless data exchange channel.

EFFECT: facilitated maintenance, increased reliability, provision of serviceability of safety and control system of crane.
