From Excavator Novice to Expert Driver

Every excavator operator aspires to be called an "expert driver," characterized by high work efficiency and stable performance. To quickly become an "expert driver," it's not just about theoretical knowledge from books; applying appropriate methods is also crucial. Today, Xiao Wang summarizes five key points in the excavating process. Mastering these points is very useful for later training and real-world practice to improve work efficiency. It is recommended to read and memorize these repeatedly.

Five Key Points to Improve Efficiency

Key Point One: Correct Posture

In standard digging actions, many novices make the mistake of incorrectly orienting the bucket teeth when entering the soil, making it seem like they are slapping into the earth. The correct approach is to insert the teeth into the soil for deeper penetration and fuel efficiency. After reaching a certain depth, hook the bucket and then lift the arm; this is the standard excavation action. Additionally, during excavation, the bucket rod cylinder should be the primary focus, with the boom cylinder as secondary. The angle of the bucket teeth should be adjusted according to the specific site conditions and should not form too small an angle with the ground.

Key Point Two: Avoid Unnecessary Movements

When rotating to load, avoid any extra movements after lifting the bucket; just perform the rotation. This not only makes the rotation quicker but also prevents the sand or soil in the bucket from falling out. Also, try to fill the bucket completely in one go; fully loaded buckets each time can save a lot of time.

Key Point Three: Maintain a Certain Angle

Another important point is the angle of the bucket during rotation. Many novices like to keep the bucket parallel to the ground, which is incorrect. If the rotation speed is fast, this can easily cause the soil to be thrown out of the bucket due to inertia. It's better to maintain some angle between the bucket and the ground, which not only prevents soil leakage but also saves time when dumping.

Key Point Four: Focus on Technique in Hard Soil

When encountering hard soil, first dig a hole as deep as the required depth, then excavate outward along the edge of the hole. You can also use the bucket teeth to cut into the soil first, then scoop it all up in one go, saving time and improving work efficiency.

Key Point Five: Utilize Inertia for Unloading

When unloading soil, many novices rely solely on the bucket-opening action, which is inefficient. This not only slows down the unloading process but also leads to incomplete dumping. Continuously shaking the bucket to empty it can waste a lot of unnecessary time. The correct unloading posture is to first retract the bucket, then quickly open it, using inertia to throw out the soil. This method not only improves unloading efficiency but also ensures cleaner unloading.

Although the above five points are the most commonly used basic actions for excavators in daily operations, they involve many details that many novice operators may not fully grasp. As the saying goes, "details determine success or failure." Only by paying attention to details and continuously accumulating and summarizing experiences can one grow faster.
