The invention discloses a fire fighting truck telescopic boom structure. The fire fighting truck telescopic boom structure comprises a truck body. The fire fighting truck telescopic boom structure is characterized in that two telescopic booms arranged symmetrically are hinged to the truck body, and the two telescopic booms are sleeved with double sleeves in a sliding mode; the double sleeves are hinged to the operating end of a telescopic boom cylinder, and the bottom end of a cylinder barrel part of the telescopic boom cylinder is hinged to the truck body; an inhaul cable arm matched with the telescopic booms is arranged, and sleeved with a sleeve in a sliding mode; the sleeve is hinged to the operating end of an inhaul cable arm cylinder, and the bottom end of a cylinder barrel part of the inhaul cable arm cylinder is also hinged to the truck body; a plurality of inhaul cables are connected between the telescopic booms and the inhaul cable arm; the telescopic function of the telescopic booms and the inhaul cable arm is achieved through the same telescopic structure. The fire fighting truck telescopic boom structure is simple, ingenious in design, and capable of greatly increasing the stretching out upper limit of a scaling ladder and achieving rapid extension.
