Project Background
The Ruhr District in Germany is a traditional coal-producing area in Europe, where coal mining is highly intelligent. All excavators are equipped with intelligent operation and maintenance systems. The requirements for bucket teeth are not only high performance, but also the ability to access the equipment intelligent monitoring platform to realize real-time prediction of wear and service life.
Bucket Teeth Selection
Liebherr R9800 exclusive high-chromium alloy steel bucket teeth were selected. This type of bucket teeth is made of multi-layer composite steel plate with laser cladding technology, and embedded with micro strain sensors to become "intelligent bucket teeth", which can transmit real-time data such as impact load and wear degree.
Application Effect
The high-chromium alloy steel material increases the wear resistance life of bucket teeth by 45% in coal mining, and the laser cladding layer effectively resists the impact and wear of gangue. The embedded sensors can transmit bucket teeth data to the mine intelligent platform in real time, predict the remaining service life through AI algorithm, and reduce the unplanned replacement rate of bucket teeth by 55%. At the same time, the intelligent data provides a basis for the optimization of bucket teeth profile and material, forming a closed loop of "use - monitoring - optimization" and continuously improving the adaptability of bucket teeth, making it a typical case of intelligent mine bucket teeth application in Europe.
