Frequently asked questions

What is the function of the Load Moment Indicator?

The LMI provides the crane operator with essential information to operate the machine within design parameters, including boom angle, working radius, rated load, and total calculated weight.

What causes Error Code E01?

Error E01 is caused by falling below the radius range or exceeding the angle range specified in the load chart, often due to hoisting the boom too far.

What happens when limits are reached?

When limits are reached, an overload warning signal is generated at the operator's console, and crane functions such as hoist up and boom down will be stopped.
