Excavator is a kind of heavy mechanical equipment for digging earthwork, which is mainly composed of power system, hydraulic system, control system, rotating system and working device. Among them, the role of the power system is to provide the power required by the excavator, while the hydraulic system is driven and operated by hydraulic oil. The rotation system is used to control the rotation direction and Angle of the excavator, and the working device is the key for the excavator to complete various operations.

When excavating, the excavator first needs to extend the bucket to the working range, and then press the bucket from the top surface down into the soil, and dig up the soil through the rotation of the bucket. During the excavation process, the excavator needs to be adjusted continuously to ensure the safety and effectiveness of the operation.

When carrying out excavation operations, it is necessary to pay attention to the following operational skills:

1. Choose the appropriate bucket and bucket teeth according to the needs;

2. Control the moving speed of the excavator to avoid adverse effects on the operation of too fast or too slow;

3. In the digging process, pay attention to the Angle and direction of the bucket, keep the bucket parallel to the ground, and avoid the bucket sinking too deep;

4. Rotate control as required to ensure that the excavator bucket and the required digging position are aligned.

Through the study and mastery of the above operation skills, we can complete the excavator excavation operation more accurately and efficiently, and improve our work efficiency and work quality.

In short, the excavator plays an important role in the excavation work. In actual operation, we need to have a full understanding of the structure and working principle of the excavator. Through continuous learning and practice, we can master the operation skills of the excavator in order to better complete the excavation operation of the excavator and improve our work efficiency and safety.
