What does LMI stand for?

• A. Load moment indicator
• B. Lift monitoring interface
• C. Load management indicator
• D. Lift measurement instrument

Answer: (A)

LMI stands for Load Moment Indicator. This safety device on cranes monitors the load moment—the weight of the load multiplied by its distance from the crane’s pivot (the radius). By comparing this moment to the crane’s rated capacity, it can alert the operator and sometimes automatically limit hoisting or other movements if the moment becomes unsafe. This helps prevent tipping or overloading. The other terms don’t reflect what this device measures or does, so they aren’t correct descriptions.
