Dragline is the largest equipment ever built on this planet. It has the ability to excavate very deep down the earth. Word drag is used because it has the ability to drag material at far distance from the machine. Dragline consists of drag rope, large bucket, boom, hoist rope and driving motors. As shown in the figure;
