Guide to Using Bucket Teeth

01 Selecting the Right Bucket Teeth

　　The choice of bucket teeth should be based on the specific working environment. The right tooth type can reduce digging resistance and save fuel. Generally speaking, for standard earthmoving operations, flat-tip earthmoving bucket teeth are recommended; for excavating hard, blocky rock, RC-type rock bucket teeth are suitable; and for excavating blocky coal seams, TL-type pointed bucket teeth are typically used, as they improve coal recovery rates.

02 Replace Bucket Teeth Promptly

　　When the tips of the bucket teeth are severely worn, the force required for the machine to perform digging operations will inevitably increase significantly, leading to higher fuel consumption and reduced work efficiency. Therefore, it is essential to replace worn bucket teeth with new ones as soon as significant wear is detected.

03 Replace Tooth Holders Promptly

　　The wear condition of the tooth holders also significantly affects the service life of the bucket teeth. It is recommended to replace the tooth holders once they have worn down by 10%–15%. This is because excessive wear creates a large gap between the tooth holder and the bucket tooth, altering their fit and the point of force application. This change in force distribution may cause the tooth holder to fracture.

04 Daily Inspection of Bucket Teeth

　　As part of the machine’s daily maintenance routine, spend a few minutes each day inspecting the bucket teeth. Focus primarily on checking the degree of wear; if wear is severe, consider replacing the tooth sleeves. Additionally, kick the bucket teeth with your foot to check whether they are securely fitted. If any teeth are loose, tighten them immediately.

05 Rotate Bucket Teeth at Regular Intervals

　　Practical experience shows that, during normal operation, the outermost bucket teeth wear out 30% faster than the innermost ones. It is recommended to rotate the inner and outer bucket teeth after a period of use to ensure more even wear across both sides.
