The invention discloses a telescopic arm structure of a truss type crane. The telescopic arm structure comprises a car body, a main arm and an auxiliary arm, wherein the car body is provided with the main arm; the other end of the main arm is connected with the auxiliary arm by a connecting shaft; a telescopic arm is arranged at the front end of a fixed arm on the main arm; a telescopic cylinder is arranged at the outer side of the fixed arm; a telescopic support rod is arranged at the front end of the telescopic cylinder; the front end of the telescopic support rod is fixedly connected with the side wall of the telescopic arm; the fixed arm is internally provided with a sliding wheel, and the telescopic arm can slide up and down in the fixed arm through the sliding wheel. According to the telescopic arm structure of the truss type crane, the main arm comprises the fixed arm and the telescopic arm, and the telescopic arm extends outside when the lifting height of the crane can not meet the using requirements of people, so that the lifting height is increased, a weight can be lifted to the higher part, and the using requirements of people can be met; the novel telescopic arm structure of the crane is simple in structure and novel in design.
