The invention relates to a crane anti-rail-gnawing device including four special displacement sensors, an analog quantity input module, an analog quantity output module, three proximity sensors, a PLC system, a signal line and a special sensor mounting bracket. The four displacement sensors are installed on the four corners of a crane for continuous real-time measurement of the relative distance value of a wheel and a track, then according to the measured value by use of the PLC system, frequency of each frequency converter of the crane can be changed in real time for control of the speed of each wheel of the crane, and ultimately the crane wheel always runs on the track centre.
