What must be fitted to turnbuckles used for tensioning counterweights to prevent loosening?

Turnbuckles are commonly used in rigging to adjust the tension of cables, ropes, and other rigging components. When it comes to tensioning counterweights, it is crucial to ensure that the turnbuckles do not loosen over time due to factors like vibration or movement.

Locking plates are specifically designed to secure the turnbuckles in place, preventing any unintended loosening. They provide a reliable mechanism to ensure that once a desired tension is achieved, it remains stable. The presence of locking plates helps maintain consistent performance and safety in rigging applications.

While options such as elastic bands, safety pins, and support cables have various functions, they don’t specifically address the issue of maintaining tension in turnbuckles. Elastic bands may provide some friction but lack the structural integrity needed for safety and reliability. Safety pins can secure components but do not effectively prevent loosening as the locking plates do. Support cables are vital for overall rigging safety, but they do not prevent turnbuckles from loosening. Therefore, the use of locking plates is the most effective method to maintain the tension required in counterweight applications.
