What is the main function of a load moment indicator?

To measure the height of the crane
To help prevent overload by measuring load and crane capacity
To assist in moving the crane
To calculate wind speed impacts

The correct answer is: To help prevent overload by measuring load and crane capacity

The main function of a load moment indicator is to help prevent overload by measuring the load being lifted in conjunction with the crane's capacity. This ensures that the crane operates within safe limits to avoid structural failure or accidents due to overload. By continuously monitoring the load moment, which is the product of the load weight and its distance from the crane's pivot point, the indicator provides real-time information to the operator. This information is crucial for making informed decisions about lifting and positioning loads safely. While the other options may touch on aspects of crane operation, they do not directly relate to the critical safety function that the load moment indicator serves in preventing overload scenarios.
