The invention relates to a moment limiter of a crane. The moment limiter comprises a main controller, a CAN data collection card, a length/angle sensor and a hoisting weight sensor, wherein the data output end of the length/angle sensor is connected with the input end of the CAN data collection card; the data output end of the hoisting weight sensor is connected with the input end of the CAN data collection card; and the output end of the CAN data collection card is connected with the input end of the main controller. Detection data are collected/transmitted by adopting the manner that a conventional sensor is combined with CAN data collection/transmission; and when hoisting equipment works, all the detection data are collected/transmitted through the CAN collection card to a control host of the moment limiter, analog quantity signals are transmitted through a CAN bus, interference caused by circuits and the external world to signals is effectively avoided, and the system reliability is improved.
