What should suspension ropes and pendants be maintained with to ensure they are in good condition?

Suspension ropes and pendants must be maintained with cotter pins to ensure they are secured properly and in good working condition. Cotter pins are used to secure nuts and bolts, preventing them from loosening due to vibration or movement during operations. By using cotter pins, you can ensure that critical connections between components remain intact, thus enhancing the overall safety and reliability of the suspension system. Proper maintenance of these fasteners is crucial, as any failure could lead to significant safety hazards, including potential loads falling or equipment malfunctioning.

In contrast, tools like wrenches are used for fastening and unfastening, but they do not serve the purpose of securing suspension components themselves. Safety chains and clamps have their own specific applications, but they are not the primary means of maintaining suspension ropes and pendants in a secure manner.
