HOISTING AND TRANSPORT UNIT EQUIPPED WITH DRUM WINCH WITH ROPE MONITORING DEVICE Russian patent published in 2020 - IPC B66C23/88 B66C23/90 B66C13/16 

FIELD: lifting devices.

SUBSTANCE: lift-and-transport unit (3) equipped with single-rope drum winch with rope drum (5) driven from winch drive (4). Lifting and transporting plant (3) comprises rope control device, freely transported on hoisting rope (8) transport facility (11), and coupling (10) made for connection of hoisting rope (8) with transportation facility (11). Rope control device has a load measuring pin as a component of coupling device (10) and a channel for transmitting the measurement signals registered by the pin to the data processing device. Data processing device for analysing measuring signals of the load measuring pin is designed so that when a jump of the signal of the measuring signal occurs, a violation of the operating mode is detected. Cable rope grommet (8) is put on pin of load measurement on coupling (10). Between the grommet and coupling (10) there is additionally a safety pin, which penetrates through hole in the coupling device and in the grommet. Through hole in grommet and/or through hole in coupling includes safety pin with formation of annular gap. Also disclosed is a method of monitoring a rope.

EFFECT: reliable detection of violation of operating conditions, high measurement accuracy.
