The price of bucket teeth varies greatly depending on the manufacturing process.

  • Sand Casting
    Sand casting has the lowest cost, and the level of craftsmanship and quality of gears is not as good as fine casting and forging. Therefore, the price is the cheapest among all processes.
  • Precision Casting
    Precision casting: moderate cost, but very strict requirements for raw materials and high technical level. Some precision casting gears are even better than forged gears in terms of wear resistance and quality due to their composition. At present, precision casting is the mainstream manufacturing process of bucket gears in the market.
  • (Note: If the number of teeth is high, then the cost performance of the teeth is very high, and precision casting teeth are good in terms of price, quality, cost performance and wear resistance)
  • Forging Casting
    Forging casting: is the highest of the three processes, the level of technology and bucket teeth quality is also the best, so the sales price is also the most expensive, but can ensure that the industrial level of forging casting bucket teeth and quality teeth is the best!
  • (Underlined: If the excavator is doing earthwork, the annual replacement frequency and bucket teeth demand is relatively small, it is recommended that you choose forging and casting bucket teeth, although the price is much higher, but the service life, yield process and quality is the best)

Replacement cycle of bucket teeth

  • The bucket tooth replacement cycle depends on the construction environment and the degree of wear and tear of the bucket teeth, for example, the excavator has been doing earth, then the degree of wear and tear of the bucket teeth is relatively small, generally about 4-5 months to replace once.
  • If it is a rock bucket to replace the bucket teeth frequency is faster, like granite is generally about a week to replace the bucket teeth, of course, this cycle is not fixed, according to the bucket teeth good or bad, the actual operation of the degree of attention to determine the frequency of bucket teeth replacement.

Daily maintenance of bucket teeth


1, keep sharp: excavator both sides of the bucket teeth generally wear about 30% faster than the bucket middle bucket teeth, when both sides of the bucket teeth than the bucket middle bucket teeth wear much shorter, the bucket teeth both sides and the middle interchangeable position to continue to use, indirectly increase the service life of the bucket teeth.

Warm tip: If the middle bucket teeth and the two ends of the bucket teeth are 2~3cm apart, they can be swapped.
2, digging operation angle to pay attention to: bucket teeth perpendicular to the work face down digging, to avoid breaking bucket teeth due to excessive tilt.

3、Tooth seat wear: When the tooth seat wears 10-15%, it is recommended to replace the tooth seat. The large gap between the worn bucket teeth and bucket teeth will lead to changes in the bucket teeth and the seat, resulting in the bucket teeth breaking due to changes in the force point.

4, pay attention to the driving method: excavator driving method to improve the utilization of the bucket teeth is also very critical, excavator drivers try not to close the bucket when lifting the big arm, if the driver raises the big arm when closing the bucket so that the operation will make the bucket teeth subject to an upward traction, so that the bucket teeth from above, thus tearing the bucket teeth, this operation action to pay special attention to the coordination of action. Some excavator drivers tend to use too much force in the action of the big arm to send the small arm, the bucket quickly to the rock “knock” or force the bucket to fall on the rock, which will make the bucket teeth shattered, or easy to knock the bucket on the crack, the size of the arm knocked bad.

Excavator master in the operation of excavation operations should pay attention to digging as far as possible, bucket teeth perpendicular to the work surface downward digging, or outward inclination of no more than 120 degrees, to avoid bucket teeth due to tilt angle is too large. Also note that do not swing the excavation arm left and right under high resistance, which will make the bucket teeth and tooth seat fracture due to excessive force left and right, because the mechanical design principle of most models of bucket teeth does not take into account the design of left and right force.

5、Buying guide: If the excavator is to do earthwork, the frequency and demand for annual replacement of bucket teeth are relatively small, then it is recommended to choose forged and cast bucket teeth, although the price is much higher, but the service life, production process and quality is the best.

If the number of bucket teeth is relatively large, then there are requirements for the cost performance of bucket teeth, then precision cast bucket teeth are very good in terms of price, quality, cost performance and wear resistance.

Tip.
The more commonly used imported excavators in the market are: Carter, Komatsu, Hitachi, Daewoo, Kobe Steel, Hyundai, etc.

A small reminder: buy bucket teeth is definitely not a single hand to hand over money so simple, choose a good, excavators, bucket teeth and engineering completion are quality assurance, if not buy the right, light Figure of cheap, resulting in the use of a short period of time easy to bad becomes a matter of course!
