In a line-set, which component is primarily used to change the direction of load movement around obstacles?

• A. Pulleys.
• B. Counterweights.
• C. Carabiners.
• D. Shackles.

Answer: (A)

Pulleys are used to redirect the rope or cable, letting the load move around obstacles without forcing the line to follow a straight path. By guiding the line over a wheel inside a block, you can route the load around corners, around lighting or scenery, or across the grid from a convenient location while maintaining control and smooth movement. In a line-set, the counterweight system handles balancing the load, reducing the effort required to lift or move it; carabiners are mainly connection points, and shackles are rigid connectors. So the pulley’s function of changing direction around obstacles is why it’s the best answer.
