This tower crane load moment indicator（LMI） adopts the current mainstream high-performance CPU and an embedded system to detect various sensor units in real time, calculate various parameters, and provide these information to the operator through the display part.
When the operation of the tower crane exceeds the allowable safety range or is close to the collision area, the system will issue an audible and visual alarm to remind the operator to stop the illegal operation, and at the same time issue a control signal prohibiting movement in a dangerous direction.
System composition：
The core components of this tower crane load moment indicator include include a sensor group (weight sensor, amplitude sensor, height sensor, rotation angle sensor, etc.), a data processor (controller), a display terminal, and an alarm and interlocking device.
Main Features：
- Restrict the tower crane from entering its own dangerous area (maximum, small amplitude control point, maximum, small height, specific turning area);
- Restrict the tower crane from entering the range of specific surrounding buildings;
- Early warning tower crane enters the surrounding tower crane interaction area; warning and advance control of the tower crane entering the collision danger area (between the tower crane and the tower crane, between the tower crane and other cranes, and the possible collision area between the tower crane and the wire rope).
