A gin-pole derrick uses which feature to control the mast direction?

• A. Hydraulic cylinders
• B. Counterweights
• C. Jib extension
• D. Guy wires

Answer: (D)

In a gin-pole derrick, the mast direction is controlled by guy wires. These tensioned cables run from the top of the mast to anchors on the ground or to the base structure, forming stays that resist lateral forces. By adjusting the tension in each guy, the operator can tilt and point the mast in the desired direction while lifting, keeping everything stable under load. Hydraulic cylinders or counterweights aren’t what set the mast’s orientation in this setup, and jib extension changes reach rather than the mast’s pointing direction. So the feature that controls the mast direction is the guy wires.
