A loader operator is transporting a 22,000 kg articulated wheel loader. They have secured it using four separate chain assemblies. Each assembly consists of a Grade 70 chain with a WLL of 6,600 kg. What should the operator do to ensure compliance with securement regulations?

Question: A loader operator is transporting a 22,000 kg articulated wheel loader. They have secured it using four separate chain assemblies. Each assembly consists of a Grade 70 chain with a WLL of 6,600 kg. What should the operator do to ensure compliance with securement regulations?

Answer options: ✅ Add at least one more chain assembly.

• Replace all chains with Grade 80 chains.
• Ensure the chains are crisscrossed over the loader.
• Confirm the chains are connected to proper attachment points on both the loader and trailer.

Correct answer: Add at least one more chain assembly.

Explanation: The total WLL of the four chain assemblies is 4 * 6,600 kg = 26,400 kg. According to regulations (e.g., National Safety Code Standard 10), the aggregate WLL must be at least half the weight of the cargo, which for 22,000 kg is 11,000 kg. While 26,400 kg is greater than 11,000 kg, regulations further specify a minimum number of tie-downs based on cargo length and weight; generally, heavier equipment requires more substantial securement than just meeting the aggregate WLL. For an item of this weight and nature, four tiedowns may not be sufficient based on length or specific equipment features, and a minimum of six is often required for articulated heavy equipment. The question implies a check on compliance; adding more chains would increase the safety margin and potential compliance, given the weight. However, the most direct reason this is the best answer is that for a 22,000 kg load, the number of securement devices will likely need to be more than four, as regulations for heavy equipment often dictate a minimum number of tie-downs regardless of aggregate WLL, especially for preventing movement in all directions. If the question implies 'just enough', then the aggregate WLL is met, but best practice and further regulation may suggest more.
