The invention relates to a three-portal-frame material taking machine and belongs to the technical field of manned lifting equipment. The three-portal-frame material taking machine comprises a chassis, a hydraulic lifting assembly, a chain wheel lifting assembly and a material taking platform. The hydraulic lifting assembly comprises a fixed portal frame, a hydraulic cylinder and a movable portal frame. The chain wheel lifting assembly comprises a chain wheel and a chain. The fixed portal frame is erected on the chassis and fixed to the chassis, and an ejector rod of the hydraulic cylinder is connected to the movable portal frame so as to drive the movable portal frame. One end of the chain is connected to the movable portal frame, and the other end of the chain is connected to a second movable portal frame. The second movable portal frame is lifted up and down by the aid of lifting movement of the movable portal frame and with the help of the chain wheel and the chain. The material taking platform is lifted up and down by the aid of lifting movement of the second movable portal frame and with the help of a second chain wheel and a second chain. The material taking machine is of a three-portal-frame structure and can be lifted higher under the condition that the size of the complete machine is not changed; moreover, the material taking machine has the advantage of being lifted safely and stably.
