The monitoring controller 7 will record the displacement data and calculate the moving speed of the mobile electric hoist 2 through the moving time to achieve multi-data synchronous monitoring. When the moving speed is abnormal, the monitoring data and the alarm signal are sent to the control end for prompting through the wireless signal transmitter 10, and the output end of the first telescopic push rod 15 is controlled to retract and the output end of the second telescopic push rod 17 is extended, driving the first clamping block 16 and the second clamping block 18 to move to the middle and clamp on the mobile track 1, and the mobile electric hoist 2 is quickly stopped by friction to ensure the safety of lifting movement.
