Load Moment Indicator (LMI), also known as Rated Capacity Indicators (RCI),  or a Safe Load Indicator (SLI) or an Automatic Safe Load Indicator (ASLI) 

is a device which is installed on crawler cranes to alert the operator if the lift is exceeding the safe operating range of the crane.

This LMI uses the luffing method of power extraction, which needs to be machined according to the crane design size plate ring tensile sensor and installed at the end of the luffing wire rope.

The device will physically lock the machinery in circumstances it determines to be unsafe. LMI systems are usually composed of a microprocessor connected to various sensors on the crane itself. The LMI measures the angle and extension of the boom along with the load weight and compares this with the manufacturer's specifications to determine if the lift is safe.

A safe load indicator has the capability of detecting the angle, weight of load lifted, and ground radius of any lifting device. It controls the lifting equipment to the level that it tries to keep the crane functioning as per the manufacturer's suggested safety charts.

The crane is fitted with multiple sensors, for each of the measured parameters, which are then further displayed in the operator's cabin for his benefit.
