Overhead Crane Practice Test

According to OSHA, what type of chain should be used by an overhead crane?

1. Single link chain

2. Double wrap chain

3. Alloy chain

4. Steel cable chain

The correct answer is: Alloy chain

The use of alloy chain in overhead cranes is recommended by OSHA due to its superior strength and durability compared to other types of chains. Alloy chains are specifically designed to withstand high loads and have a higher resistance to fatigue and wear, making them suitable for the rigorous demands of lifting operations. This type of chain also provides better performance in terms of impact resistance and is often rated for higher working loads, ensuring safety during lifting operations. Other options may not meet the necessary strength standards required for overhead lifting applications. For example, a single link chain lacks the necessary structure to handle heavy loads effectively, while a double wrap chain does not provide the same level of integrity and safety as alloy chains. Steel cable chains, although strong, do not offer the same flexibility or resistance to wear and damage as alloy chains, making them less ideal for extended use in high-load applications. Overall, alloy chains are sets apart as the preferred choice for overhead crane operations, prioritizing safety and efficiency.
