In the field of construction machinery, where equipment safety is closely linked to operational efficiency, the Load Moment Indicator (LMI), Load Limiter, and Anti-Offcenter Loading System are collectively referred to as Safety Load Indicator（SLI）. As core technologies ensuring stable equipment operation, they play an irreplaceable role in the industry.
1. Load Moment Indicator (LMI)
The LMI relies on high-precision sensors to capture real-time changes in equipment stress. Through complex algorithms, it converts stress states into accurate moment values, which are intuitively displayed on a visual operation interface. This enables operators to promptly understand the equipment’s load status and adjust operation strategies accordingly, preventing equipment damage caused by excessive moment.
Application Scenarios: Cranes, excavators, and other heavy machinery requiring real-time moment monitoring.
2. Load Limiter
As a “guardian” of equipment safety, the Load Limiter instantly triggers audible and visual alarms when the detected load exceeds a preset threshold. Depending on the risk level, it can automatically cut off the power supply to effectively avoid structural damage from overloading and eliminate safety hazards at their source.
Application Scenarios: Loaders, forklifts, and other material-handling equipment prone to overloading.
3. Anti-Offcenter Loading System
This system uses sensors distributed at key equipment positions to monitor load distribution in real time. Upon detecting off-center loading, it immediately issues an alarm and provides deviation-correction guidance through intelligent algorithms, ensuring stable equipment operation and significantly extending service life.
Application Scenarios: Reach stackers, port cranes, and other equipment requiring balanced load management.
Integrated Applications and Synergy
These systems demonstrate remarkable effectiveness in real-world scenarios and can be mutually combined for enhanced safety:
- In construction projects, tower cranes equipped with both LMI and Load Limiter can precisely prevent tipping risks during hoisting operations.
- In port logistics, the Anti-Offcenter Loading System ensures uniform load distribution on container cranes, improving handling efficiency and safety.
When integrated with dynamic weighing systems, they form a multi-dimensional safety network, providing comprehensive protection for engineering operations.
By addressing different aspects of equipment safety—moment monitoring, overload prevention, and load balancing—these technologies work in tandem to create a robust safety framework, making them indispensable for modern engineering projects worldwide.
