In a transport system, a gripper includes long-side grippers aligned in a long-side direction of a workpiece which is cut, by machining/cutting, into a product and a skeleton including an outer frame with an overall rectangular shape and a crossbar inside the outer frame, so that both ends thereof are connected to two shorter sides facing each other, and extending in the long-side direction, the long-side grippers gripping longer sides of the outer frame of the skeleton, and short-side grippers aligned in a short-side direction with respect to the workpiece and that grip shorter sides of the outer frame. At least one of the short-side grippers moves in the short-side direction and grips the shorter sides of the outer frame. A lifter lifts or lowers the gripper gripping the outer frame and the product to separate the outer frame and the crossbar from the product.
