Provided is a multi-stage hydraulic multiplication pulley vertical lifting-type climbing platform fire truck, which belongs to the technical field of fire fighting and rescue devices. The multi-stage hydraulic multiplication pulley vertical lifting-type climbing platform fire truck comprises an automobile chassis (1), wherein a telescopic arm (2) is hinged to and mounted on the tail end of the automobile chassis (1), a rotary platform (7) is provided on the top end of the telescopic arm (2), a working arm is mounted on the rotary platform (7), and a working hopper (3) is mounted at one end of the working arm; an overturning hydraulic oil cylinder (5) is mounted on the automobile chassis (1), front hydraulic support legs (4) are mounted on the automobile chassis (1) close to the left and right positions of an automobile cab, rear hydraulic support legs (6) are mounted on the telescopic arm (2) away from the left and right positions of the automobile cab, an auxiliary supporting oil cylinder (41) is provided on the automobile chassis (1), and transition hydraulic oil cylinders (7) are mounted on the left and right positions of the tail end of the automobile chassis (1). The technical problems that the maximum height rescue radius of existing high-altitude fire trucks is small and that the maximum rescue height is limited by a hydraulic oil cylinder transmission form are solved, and the present invention is widely applied in high-altitude firefighting or rescue.
