Chain is often preferred in excavation work due to its resilience against what?

Chain is often preferred in excavation work due to its resilience against moisture. When working in excavation environments, equipment and rigging materials are frequently exposed to wet conditions, including rain, mud, and groundwater. Chains are made of metal and typically have a higher resistance to corrosion compared to other materials, especially when they are properly coated or protected. This resilience helps maintain the integrity and strength of the chain over time, ensuring that it does not degrade or fail under wet conditions.

While chains also exhibit strength in various ways, such as being able to absorb shock loads, the aspect that makes them particularly suitable for excavation work is their performance in moist environments. Proper care and maintenance can enhance a chain's resistance to environmental elements, allowing operators to use chains confidently in conditions where moisture might adversely affect other materials, such as ropes or straps.
