A tower crane monitoring device based on GPRS and U-disk memory mainly solves the problem in the prior art that accidents of the conventional tower crane happen frequently due to the lack of the monitoring device. The tower crane monitoring device is characterized in that a data processing module circuit, an A/D conversion module circuit, a single chip microcomputer with a U-disk interface, a GPRS module, a U-disk, a clock circuit and an audible and visual alarm circuit are arranged inside a casing of the tower crane monitoring device; a gravity sensor, a height sensor, an amplitude sensor, a rotation sensor and a wind speed sensor are arranged outside the casing of the tower crane monitoring device; the signal output terminals of the individual sensors are connected with the corresponding signal input terminals of the data processing module circuit; the processed signals are converted by the A/D conversion module circuit and then inputted to the single chip microcomputer; and a control signal output terminal
