The invention relates to an automatic lifting tower for forest fireproof observation. In a work state, a truss telescopic arm lifts a remote monitoring device to the position 30 m away from the ground. In a non-work state, the truss telescopic arm contracts, and a fireproof area can be monitored conveniently. The lifting tower comprises the telescopic arm of a four-truss structure, the first section is fixed, and the rest of three sections are sequentially embedded in the previous sections. A directional sliding block structure is arranged between the sections of the telescopic arm. After a four-section arm frame is erected and stretches out, the size of a tower body is sequentially reduced from bottom to top, and tenth-scale wind is resisted. A set of mechanical locks are arranged between a base of the automatic tower telescopic arm and the tower body, the mechanical locks are locked when the tower uprightly ascends, and before the tower descends and is collected, the mechanical locks are unlocked, and the tower body is integrally safe and reliable. Two pulley-steel wire pull rope sets are used in the lifting tower in a transmission manner and symmetrically arranged bilaterally, and the left side and the right side are the same in structure and function. By means of the two sets of pulley-steel wire rope systems, rigid connection between the sections of the telescopic arm is achieved. By means of a power telescopic hydraulic cylinder and the synchronous stretching and contracting of the four-section arm, stability and smoothness are achieved, and the phenomena of clamping, shaking and crawling are avoided
