🔍 Key Concepts

• Meaning of tandem in lifting operations (two units working together on one load) • Difference between a single crane, twin cranes on one pedestal, and two separate cranes • How total lifting capacity is described in crane operations (per crane vs combined)

💭 Think About

• Which option clearly involves two cranes sharing one load at the same time? • Is a "tandem" lift about the number of pedestals, the number of hooks, or how many cranes are actively lifting one load together? • For each choice, imagine the actual rigging: how many hooks/cranes are on the same load in that scenario?

✅ Before You Answer

• Identify which choices describe only one crane actually lifting the load • Check which scenario truly requires coordinated operation between two cranes on a single lift • Be sure the option you choose matches the plain-English idea of tandem = two working together on one task
