A push-pull forklift truck comprises a forklift truck, front pull arms, rear pull arms, connection blocks, chains, a pair of pull bars, turning cylinders and stretching and retracting cylinders. Both the front pull arms and the rear pull arms are formed by hydraulic cylinders. The rear ends of the front pull arms are hinged to the connection blocks fixed at the front ends of the rear pull arms so as to form two integrated pull arms. The rear ends of the integrated pull arms are hinged to frame bars of a good stopping frame at two edges of the forklift truck. The front ends of the front pull arms support the pull bars. In case that no heavy object is inserted into a forklift space below a forklift tool of the forklift truck, the pull bars are transferred right ahead of the heavy object, and the integrated pull arms retract to pull the heavy object onto the forklift truck. When the heavy object needs to be unloaded, the front pull arms rotate backwards around the chains to move the pull bars to the back of the heavy object, and the rear pull arms stretch to enable the pull bars to push the heavy object off the forklift truck. In case that the heavy object inserted into the forklift space below the forklift tool exists, the pull bars are transferred to and positioned at the position behind a door frame. The pull arms erect after retracting so as to fully empty the space above the forklift tool. No matter that the lower portion of the heavy object is inserted into the forklift space or not, the forklift tool of the forklift truck is available for use, and the usage range of the forklift truck is enlarged.
