This article discusses the Load Moment Indicator (LMI) system in cranes, including its various components such as length sensor, anti two-block sensor, load plate system, wind speed sensor, and angle and length transmitter system. It also provides an experimental analysis of wind speed and anti-block sensor systems, and a proposal for the next phases of development of the crane LMI system. The article concludes by recommending the use of modern technologies in the design and development of the crane LMI system.
