When a novice drives an excavator, the work efficiency is usually not very high, but the fuel consumption is much higher. I have led many apprentices before, and I have discovered many problems with them. Here are a few mistakes that novices often make:
The first is the problem of the shovel angle when digging. If the working device of the excavator is broken down, it mainly includes the boom (big arm), stick (small arm) and bucket, as well as the corresponding cylinders. When digging, the bucket rod is in the vertical range of about 45° in front to about 30° in the back, which is the most efficient. (The data comes from the Internet. I have not tested it specifically, and I don’t know if it is accurate. In layman’s terms, when digging, the bucket rod Don’t stretch too far, don’t shrink too close), everyone knows this. But another area where novices tend to make mistakes is the angle at which the bucket enters the soil. If the bucket is regarded as a kitchen knife, then the five bucket teeth are the blade. Just like cutting a radish, the angle of the blade should be consistent with the direction of the force to cut faster. If it is inconsistent, then you are not cutting a radish, but a radish. I’m patting the radish, or “scraping” the radish. The same is true for excavators. When digging, the direction of the force exerted on the bucket is generally an arc centered on the stick axis. The angle of the bucket teeth should be adjusted based on this, so that the bucket can easily ” Cut” into the soil.
Also, over-exploration. Many novices are afraid that the bucket will not be fully dug. They often cannot stop digging after the bucket is full of soil and continue digging until a lot of soil overflows from behind the shovel. Because the bucket is sometimes buried in the soil during excavation and the angular position cannot be directly seen, so avoiding this requires careful judgment based on experience. If the bucket is full or encounters rocks and cannot dig, the cylinder will reach the limit and the relief valve will open. Even if the operating lever is pulled to the top, it will be useless. At this time, the diesel will just be turned into a roaring noise. .
Everyone knows that the turning angle must be reduced when working. In addition to this, there is another point that few people will talk about, that is, whether the fuselage is in a horizontal position when turning. If the fuselage is on an incline, the rotation process is divided into half uphill and half downhill. It is very difficult for the excavator to rotate uphill, and for the driver, it is very difficult to turn the fuselage Stopping the level is usually as easy as two shovels of dirt!
There are many similar tips. As you become more proficient in driving skills, observe more and think more, and draw inferences from one example, you will naturally learn from others.
