The primary function is to lift and lower the massive drill string—a series of connected pipes that extend the drill bit into the earth. Modern derricks are engineered with strict load ratings and are constantly monitored for stress and alignment.
Evolution and Modern Design While the fundamental principle remains the same, derrick design has evolved significantly. As the drawworks reels in the wire rope, the traveling block moves upward, lifting the entire drill string to add another joint of pipe.
