The invention discloses a jacking anti-tipping alarm system of a self-elevating tower crane. The jacking anti-tipping alarm system is used for inclination early warning during jacking of the tower crane. The invention relates to the technical field of tower cranes. The jacking anti-tipping alarm system comprises an inclination angle sensor, a working power supply, a voice broadcaster and a jackingpump station, wherein the working power supply is connected with the jacking pump station through a power supply circuit, a signal output circuit is connected with the voice broadcaster, and the inclination angle sensor is mounted on a rotary tower body at the upper portion of the tower crane and is electrically connected with the jacking pump station, the voice broadcaster and the working powersupply respectively. In the jacking section adding operation process, when the upper structure of the tower crane is unbalanced to a certain degree, an alarm is given to a whole work site through sound, jacking operators can master the balance state of the upper portion of the tower crane in time, and tipping accidents are prevented.
