🔍 Key Concepts

• Meaning of the word tandem in lifting operations • Difference between number of cranes vs. total weight lifted • How crane configurations are named (single, twin, triple, quad, etc.)

💭 Think About

• Ask yourself: in everyday language, when two things work together in line, what word is often used? • Which choice clearly describes two cranes working together on the same load? • Is the question asking about total weight, or about the arrangement/number of cranes?

✅ Before You Answer

• Identify which option specifically involves two cranes, not one or four • Confirm that a tandem lift means two cranes sharing a single load, not multiple separate lifts • Verify that the description matches both the number of cranes and the idea of a shared hoist on one load
