How to use the weather vane brake of a tower crane?
1 Answers
Weather vane is used to unlock the brake. After the weather vane is locked, the tower crane can rotate with the wind even when power is lost. When the weather vane brake is released, the weather vane support rod props up the brake mechanism, allowing the crane's boom to rotate with wind direction. Tower cranes are the most commonly used lifting equipment on construction sites. They extend section by section to lift construction materials like steel bars, wooden formworks, and concrete.
