On construction sites, tower cranes, as a large lifting equipment, safety management is crucial. With the rapid development of sensing technology, digitization and intelligence of tower cranes have become a trend in tower crane management.

For construction cranes, the micro special technology construction crane safety technology solution systematically ensures construction safety and intelligent management and maintenance from multiple aspects such as collision prevention, wire rope monitoring, motor fault diagnosis, steel structure stress health, and driver safety operation management, allowing the crane to achieve greater benefits.

1. Tower crane anti-collision system

Preventing tower crane collisions is a very important safety task at construction sites. The micro special tower crane collision prevention system monitors the working data of the tower crane in real-time, calculates the three-dimensional spatial parameters of each equipment, and dynamically monitors the surrounding environment. When the tower crane runs too close to other equipment or workers, it sends a danger alarm in advance to prevent collision accidents.

2. Non destructive testing of steel wire ropes

As one of the most important flexible components of cranes, steel wire ropes have defects such as wear, wire breakage, decreased strength, and rust during long-term high-frequency operation. It often leads to serious safety accidents for equipment and personnel. Weite conducts non-destructive testing on steel wire ropes based on electromagnetic testing technology.

By automatically collecting changes in the stray magnetic field of steel wire ropes, combined with multiple data algorithms and steel wire rope scrap standards, quantitative detection of defects such as wear, breakage, strand breakage, rust, deformation, etc. of steel wire ropes has been achieved, and maintenance suggestions have been provided. Non destructive testing is carried out without affecting production, ensuring the safe operation of the steel wire rope.

3. Fault diagnosis multi-dimensional analysis system

The multi-dimensional analysis system for online fault diagnosis of micro special rotating mechanisms conducts multi-dimensional fusion analysis of vibration, speed, temperature, current and other status signals of crane motors, reducers, wheels, etc. Combined with intelligent diagnostic algorithms, it achieves real-time intelligent diagnosis, pre alarm prediction, trend analysis, offline data analysis, etc. of crane equipment, achieving early diagnosis of fault types, fault probabilities, and fault levels, and providing maintenance suggestions, Ensure the normal operation of the rotating mechanism.

4. Metal structure stress health monitoring

The main failure mode of cranes in long-term lifting work is mechanical fatigue damage caused by the influence of alternating stress on metal structures or components under random alternating loads. Weite analyzes its failure modes and stress conditions, installs stress sensors at key points, monitors stress status and deformation, obtains corresponding stress spectra, and evaluates the safety status of metal structures through mathematical model analysis combined with stress fatigue analysis theory to prevent safety accidents caused by crane metal structure failure.

5. Driver fatigue and distraction warning system

The system utilizes intelligent cameras to monitor the driver's cab in real-time, and uses graphic algorithms to analyze and process the cab images frame by frame, recognizing the driver's facial status, body posture, use of mobile phones or items, etc. in real-time. By using logical judgment and rule algorithms, determine whether the driver is experiencing fatigue and abnormal operations such as making phone calls, and automatically issue an alarm. The equipment is convenient and practical, with high accuracy, fast feedback speed, and does not affect the normal work of the driver.

The safety technology solution for micro special construction cranes maximizes construction safety, reduces costs and increases efficiency, and ensures the personal safety of workers and the smooth progress of the project through intelligent technical means such as collision prevention, wire rope monitoring, drive mechanism fault diagnosis, steel structure stress health, and driver safety operation management.
