Regularly Exchange Bucket Teeth: The outermost bucket teeth wear 30% faster than the innermost ones. After some time, it's crucial to swap the inside and outside bucket teeth to balance wear and prevent premature failure.
Optimize Excavation Angle: Excavator operators should be mindful of the angle of excavation. When digging, try to keep the bucket teeth perpendicular to the surface to avoid excessive wear or breakage caused by too much tilt. This will prevent the bucket teeth from breaking due to unnecessary stress.
Avoid Excessive Swinging: When encountering large resistance, operators should avoid swinging the arm left and right, as this can cause undue stress on both the bucket teeth and the gear seat. The forces on the left and right are not designed to be that high, and excessive force can cause damage to both parts.
Monitor Tooth Seat Wear: The wear of the tooth seat significantly impacts the lifespan of the bucket teeth. Once the tooth seat wears by around 10%, it's time for replacement. A worn-out tooth seat creates a larger gap, disrupting the fit between the tooth and seat, altering the force distribution and increasing the risk of bucket tooth breakage.
Excavator Operator Practices: The way an excavator is driven plays a key role in improving the lifespan of the bucket teeth. For example, operators should avoid retracting the bucket when lifting the boom. Additionally, operators must ensure coordinated movements when extending the arm or delivering the forearm to avoid using excessive force, which can cause the bucket teeth to crack or break.
