How should all pins be secured during crane operation?

During crane operation, securing pins with cotter pins is essential for maintaining safety and ensuring that components do not unintentionally become dislodged. Cotter pins are designed specifically for this purpose and are used to secure parts that are prone to rotational or linear movement. When properly installed, cotter pins hold the pins in place even under the dynamic loads and vibrations that occur during crane operation, preventing accidents and equipment failure.

Cotter pins can easily be inserted through a hole in the pin and then bent at the ends to secure the connection. This simple yet effective mechanism makes them a preferred choice in various mechanical applications, especially in heavy lifting equipment like cranes.

Other methods, such as lock washers, glue, or screws, may not offer the same level of reliability or appropriateness in the context of securing pins on cranes. Lock washers typically prevent loosening of a bolt or nut rather than securing a pin. Glue may not withstand the physical stress or environmental factors encountered during crane operations. Screws, while useful in many applications, do not provide the necessary freedom of movement required for certain pin applications, which can limit their effectiveness in this context.
