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.
