Crane Load Moment Indicator vs Safe Load Indicator: LMI, SLI, RCI, and RCL Explained With Standards and Specifications
A Load Moment Indicator (LMI) continuously monitors load weight, boom angle, working radius, and rated capacity on mobile cranes, triggering visual and audible alarms — and automatic cutoff — when the crane approaches overload. A Safe Load Indicator (SLI) provides a simpler layer of load monitoring, typically measuring only hoist line tension against a pre-set […]
