The continuous movement of the excavator requires side-turning positioning skills and leveling skills. The movements are done in sequence. Loading the truck after digging also requires leveling skills. The specific operating skills and steps are as follows:

Square positioning: The continuity of digging movements means that the angle between the big and small arms should be kept at about 90-110 degrees as much as possible. The contact angle between the bucket bottom plate and the ground is 60 degrees for loose soil and 30 degrees for hard soil; (excellent When excavating the soil layer, you also need to use a bucket to pry.) When digging, the angle of the bucket is adjusted, and the thrust of the forearm cylinder is the main force. When the bucket and the big arm feel that the recovery of the forearm is slowing down, they start to Cooperate with the action; when the bucket is 3/4 full, quickly retract the bucket and raise the arm to rotate. Positioning means accurately sensing the advance. When rotating, the main line of sight of the eyes should look at the direction of the rotation, and the peripheral vision should look above the bucket and forearm. When it is about 1 meter in front of the unloading point, start to loosen the rotation extension. The forearm opens the bucket with a compound action to position it. (Remember not to use anti-rotation movements for positioning)

Leveling skills: Leveling is a type of work that combines various actions, including a series of complete cooperations such as digging, sweeping, positioning, and processes. As a skilled master, the most important thing is to learn to formulate your own work plan under any working conditions, especially leveling work. Formulate the basic plan for leveling: first dump the excessively high earthwork into the low-lying areas, and then roughly level the forward and backward routes of the excavator; determine the elevation, formulate the leveling route, and start fine-leveling; in short, always refer to the broad surface. When leveling, always determine the difference between the elevation and the bucket. Use the three points in front, left and right of the bucket as a plane, and level from left to right (right to left is also acceptable). (If the gap is not big, you can use a bucket to level it and sweep it across)

Loading skills:

Fully loaded. You can't do it half-shovel and half-shovel.

Reduce the rotation angle. 30% of the time when loading a truck is rotating, and reducing the rotation angle of the truck will make your loading speed much faster. Specific method: For example, if the dump truck is directly in front of you, your material picking range is to your left and right (that is, within 90 degrees from the center of the truck).

The right height (your parking platform). If it is too high, it will take time to lift the big arm. If it is too short, it will not be fully loaded with too little material, which is a waste of time.

Let the dump truck wait for the excavator. The best way is to put two dump trucks in front, and load this one and that one (the truck on the left will pick up materials on the left, and the truck on the right will pick up materials on the right).

Loading method. This is related to personal habits. Some people load the front first and others load the back first. However, it is faster to load the back first because your bucket is a backhoe and dumps materials backward.

Choose a bucket with a wider blade, which will speed up your loading and unloading speed.
