HOISTING MACHINE EQUIPMENT DISPLACEMENT DETECTOR (VERSIONS) Russian patent published in 2010 - IPC B66C13/18 G01B7/00 

FIELD: machine-building.

SUBSTANCE: invention related to device versions for using in hoisting machines control and protection systems. Detector has an activator with constant magnet, installed with rotation ability in case of controlled device displacement, two sealed contacts, installed with ability of actuation under constant magnets field effect, in order defined with magnets circular displacement or rotation direction, output device and self-contained power supply source, connected to the sealed contact first outputs. According to first version device contains diode-condenser block and micro controller. Micro controllers output/input connected to input or bi-directional output/input of the output device. The second sealed contacts outputs connected to the micro controller inputs via the diode-condenser block, and diode-condenser block executed with ability of micro controller supply voltage generation or control of this supply. According to the second version the second sealed contacts outputs connected, directly of via filtrating chains, to micro controller outputs, which supply outputs connected to the self-contained power supply source.

EFFECT: bigger time interval betwen technical maintainance procedures, safety during increase hoisting machine operation, detector lifetime increase.
