What does LMI stand for in crane equipment?

• A. Load Moment Indicator
• B. Lift Measurement Instrument
• C. Load Monitoring Interface
• D. Limit Manipulation Indicator

Answer: (A)

LMI stands for Load Moment Indicator. This safety device on cranes calculates the load moment, which is the weight of the load times its distance from the crane’s pivot point, using current boom angle and extension. It compares that moment to the crane’s rated capacity for the given configuration and alerts the operator, or even limits movement, to prevent overloading or tipping. Other terms like Lift Measurement Instrument, Load Monitoring Interface, or Limit Manipulation Indicator aren’t the standard names for this system, so the correct concept is the Load Moment Indicator.
