FIELD: transport.
SUBSTANCE: proposed system comprises digital computer with memory, hoisting machine parametre pickups connected to digital computer data inputs and incorporating at least one pickup of load and/or hoisting machine components spatial position, and/or machine drive speed. It comprises also device to measure supply voltage parametres connected to digital computer and actuator unit coupled with hoisting machine control system and digital computer. Digital computer can compare measured parametres of supply voltage with tolerable values stored in memory and generate inhibit instructions in case supply voltage parametres fall beyond tolerances. Digital computer and actuator unit generate signal to cut off separate drives of hoisting machine in case supply voltage parametres fall beyond tolerances for machine drives and control system.
EFFECT: higher safety, efficiency and reliability.
