The invention discloses a climbing fire truck and a supporting leg telescopic device and method thereof. The supporting leg telescopic device for the climbing fire fighting truck comprises a supporting leg box arranged on a fire fighting truck frame, a first supporting leg sleeved with the supporting leg box in a sliding mode, a second supporting leg sleeved with the first supporting leg in a sliding mode, a first oil cylinder perpendicularly arranged at the free end of the second supporting leg, and a pressure sensor arranged between the first oil cylinder and the second supporting leg. A first support is fixed to one end of the supporting leg box, a second oil cylinder is fixed to the first support, and the second oil cylinder comprises a push rod connected to the first support and a cylinder barrel arranged on the outer side of the push rod in a sleeving mode. Through the effective weight reduction design and the installation structure, high smoothness, convenience and reliability are achieved, the stress of the supporting leg can be measured in real time by reading the numerical value of the pressure sensor in the use process, then it is confirmed that the first oil cylinder bears force correctly all the time and does not leave the ground, the actual use requirement can be better met, and the application range is wide. And the method has good practicability and adaptability.
