4 Point of Excavator teeth, help you save money

The excavator teeth is an important consumable part on the excavator. Similar to a human is a combination of a tooth holder and a tooth tip. The two are connected by a pin. Since the tooth wear failure portion is the tooth tip, the tip can be replaced.
Many of the tooth materials are wear-resistant steel materials, and the materials used by different bucket teeth manufacturers are different; there are ZGMn13 (high manganese steel), 50Mn, 30CrMnSi, 30CrMnTi and so on.

Type of Bucket Teeth

In the process of using the teeth, it is necessary to look at the working environment, to determine the type of the tooth, generally excavation, weathered sand, surface media, etc. to use flat mouth teeth. For the hard rock with block shape, the RC type of tooth is used. For the block coal seam, the TL type tooth is generally used, and the TL tooth can increase the coal output rate. In actual use, users often like the teeth of the universal RC. If it is not a special case, we do not recommend the use of RC type teeth. It is best to use flat teeth, because the RC teeth are worn after a period of time, like a 'fist. 'Increase the excavation resistance, waste power, and the flat mouth teeth always maintain a sharp surface during the wear process, reducing the excavation resistance and saving fuel. This also means lower costs.
In addition, advice on the service life of the excavator's teeth!

1) During the use of the bucket teeth of the excavator, the outermost bucket of the bucket is 30% faster than the innermost wear. It is recommended to change the position inside and outside the bucket after a period of time. This can improve the efficiency of the excavator.

2) The driving method of the excavator driver is also critical to improving the utilization of the tooth. The excavator driver should try not to collect the bucket when lifting the boom. If the driver lifts the boom, he will take the bucket. It will cause the tooth to receive an upward traction force so that the tooth is torn from the top, and the tooth is torn. This operation must pay special attention to the coordination of the action. Some excavator drivers often use excessive force to amplify the arm and send the arm, and quickly slam the bucket onto the rock or force the bucket to fall on the rock, which will smash the bucket. Or it is easy to crack the bucket and break the big and small arms.

3) The wear of the toothed seat is also very important for the service life of the tooth of the excavator. It is recommended to replace the tooth seat after the tooth seat wears 10% , because there is a large gap between the toothed seat and the tooth. The gap between the tooth and the tooth holder changes, and the force point changes, and the tooth breaks due to the change of the force point.

4) The excavator driver should pay attention to the angle operation during excavation. When mastering the excavation as much as possible, the bucket teeth are perpendicular to the working surface when digging, or the camber is not more than 120 degrees, to avoid the tooth due to excessive inclination. . Also be careful not to swing the excavating arm to the left or right with a large resistance. This will cause the tooth and the tooth to be broken due to excessive force on the left and right. Because the design mechanics of most types of teeth do not consider the left and right forces. design.

Some experience in buying excavator bucket

Have no idea how to choose the excavator bucket? In these post we would like to introduce you some tips about that, and talk about some company about this product.
The first and the most important factor is---has to be actually sturdy, dig with great performance and cost-effectiveness and a good price that permits you to quickly get back the cost of bucket.

 You determine to improve your fleet by buying a brand-new digger, carefully deciding on lots of brands as well as designs. As well as finally, a new vehicle for you. A small trouble - the digger came without add-ons - is actually solved, and also you hang up an aged rustic 10-year-old bucket. But after a couple of weeks you begin to recognize that the performance of the brand-new bulldozer has not come to be more than it was actually with the old one, and also the gas economic climate is actually not detectable in comparison with the aged machine!
 In reality, many excavator buckets commonly dig absolutely no far better than an ordi…

Show You How To Put An Air Conditioner in Excavator

As an excavator driver, we kept working in all kind of weather, no matter how cold it is, how hot it is, even it is the heavy rain. But in all kind of weather, I hate hot.  In other words,  I hate the summer. That s too hot. Sweating all day. But thanks God air conditioner save my life. Maybe we should thank for Willis Haviland Carrier,this guy creat air conditioner.
Here we want to you , how smart we are.  We put the home used air condition in excavator.
The excavator is new Chinese brand. So u know that it is hard to make everything beautiful. But that s ok. Not too many big problem, but some time small problem. Like this time the air condititoner was broken. At the noon, full of sunshine, so it is very hot. We guess the temperature over 40 degree.  But we can not feel the temperature down when we turn on the air conditioner 6-7 minutes.  Does it broken.? This is our first felling. So make an inspection. The result is compressor did not work! So we check all units , one by one.  Finall…
