Methods of prolonging service life of excavator bucket teeth

Good quality Heavy Duty Excavator Bucket for sales
We tried our first order in 2018, which was two years after I exchange my business card with Alice in 2016 Bauma conexpo India. Our supplier didn't finish our order on time, and it will cause around 100,000 USD lose to us. That's when we tried Huitong the first time. Huitong is good at dealing with rush orders, and the quality is very good.

I work with Huitong the first time when I started my importing business. I've got tons of market insights from Jeremy. He is such a good friend being very tolerant to my bad temper. In 2017, Jeremy helped me handle a problem of bill of lading, which is caused by me. Huitong always emphasize that we should deal with the problem as soon as it occurs.

Methods of prolonging service life of excavator bucket teeth
Methods of prolonging service life of excavator bucket teeth

1.Practice has proved that during the use of excavator bucket teeth, the outermost tooth of the bucket wears 30% faster than the innermost tooth. It is recommended to reverse the position of the inside and outside of the excavator bucket teeth after a period of use.


2.During the use of excavator bucket teeth, it depends on the working environment to determine the specific type of bucket teeth. Normally, flat-head bucket teeth are used for soil excavation, weathered sand, surface coal, etc. RC type bucket teeth are used for digging massive hard rock, and TL type bucket teeth are generally used for digging massive coal seams. TL bucket teeth can increase the rate of coal lump production. In actual use, users often like general-purpose RC type bucket teeth. It is recommended not to use RC type bucket teeth under special circumstances. It is best to use flat-head bucket teeth, because after a period of time, RC type bucket teeth will become bigger like a fist. The digging resistance is reduced and power is wasted. The flat-mouth bucket teeth always maintain a sharp surface during the wear process, which reduces the digging resistance and saves fuel.

3.The driving method of the excavator driver is also very important to improve the utilization of the excavator bucket teeth. The excavator driver should try not to retract the bucket when lifting the boom. If the driver raises the boom, the bucket is retracted. It will cause the bucket teeth to receive an upward traction, so that the bucket teeth will be torn from the top, and the bucket teeth will be torn. This operation action should pay special attention to the coordination of the action. Some excavator drivers often use too much force in the action of expanding and sending the forearm, and quickly "knob" the bucket against the rock or force the bucket against the rock, which will break the bucket teeth. Or it is easy to crack the digging bucket and damage the big and small arms.


4.The wear of the tooth seat is also very important to the service life of the excavator bucket teeth. The tooth seat is worn out by 10%-after 15%, it is recommended to replace the tooth seat, because the excessively worn tooth seat and the bucket teeth There is a large gap between the bucket teeth and the tooth seat, and the force point has changed, and the bucket tooth is broken due to the change of the force point.

5.The excavator driver should pay attention to the digging angle during operation, try to master it when digging, and the bucket teeth are perpendicular to the working surface when digging, or the camber angle is not more than 120 degrees to avoid breaking the bucket teeth due to excessive inclination. Also be careful not to swing the digging arm left and right under the condition of large resistance, which will cause the excavator bucket teeth and gear seat to break due to excessive force on the left and right, because the mechanical design principle of most models of bucket teeth does not consider the force on the left and right. design.
