The essentials of the excavator leveling field, how to level the field with a small excavator

1.The excavator itself should be stopped.

The tip of the bucket tooth is relatively horizontal with the crawler, (note: it is the left and right level, and the front and rear levels can be overcome) to pay attention to whether the excavator itself is stable and flat.

2.Thinking clearly.

After stopping the excavator, stretch out the small arm and press down the big arm. At this time, the angle between the small arm and the large arm is greater than 90 degrees. Raise the big arm, close the small arm, and move at a constant speed to ensure the horizontal operation of the bucket teeth.

When the angle between the forearm and the large arm is 90 degrees smaller, the forearm continues to retract. Push your arms down. Its speed must still ensure the horizontal operation of the bucket teeth.

3.Skillful operation.

Each brand of excavator has different flow distribution of large and small arms and sticks, so the matching speed is also different. It is important to familiarize yourself with the speed of the upper and lower arms. The proper coordination of the two can ensure that the tip of the bucket tooth is horizontal.

4.Adapt to local conditions.

For larger venues, start at the very edge of the site.

5.Overcome visual errors and visual fatigue.

Everyone's visual error is regular, such as the higher the income, the lower the income.

6.The enemy changes, I change.

The situation at the venue is ever-changing. gravel, sand, thin mud, hard soil. Every situation requires us to be adaptable.

Small excavator flat field technical essentials:

In the process of leveling the ground by the excavator, the scattered stalls are similar to a triangular change over the tomb. The three sides of this triangle are the boom, the stick, and the ground. When the excavator is leveling, there is a trigonometric relationship between the operation of the boom and the stick.

That is to say, the length of the stick cylinder extension needs to correspond to the extension or retraction of the boom cylinder to control the bucket to maintain linear motion and trim the flat ground. This control of the stick and boom when leveling the ground takes a long time to become proficient. This is the most important and basic action of the excavator, and it is the basis for other actions.

When the excavator levels the ground, it generally uses the middle A and B sections of the distance before the stick perpendicular to the ground. Section A is generally to grab the excess soil back, and sections B and C are the best range for leveling the ground. If the soil layer is thin, the soil is generally thrown back in section D.

If the soil layer is thick, hook the bucket and lift the arm between the C sections. Complete a perfect digging move. Many times of the same repetition can form a plane.

It is worth noting that in daily work, the excavator leveling the ground is an operation that requires careful observation and patient operation. The observation of the height of the ground and the comparison of reference objects need to be correctly judged, which requires a long period of work experience. If there is only a small amount of loose earth and rock on the ground, it needs to be leveled.

The driver often uses the excavator to rotate the soil and rock to "sweep" away, and it should be noted that the rotation force will be relatively small, and when encountering hard soil or more soil, it is "sweeping" not moving. Therefore, it is necessary to use various operating methods reasonably according to different situations.

It's been two years since you opened and you can't come to the venue, how did you open it? It's good to practice more!

Leveling the ground is the most basic job in the work of an excavator! It is also one of the most visible jobs for the level of operation!

Its characteristic is that the forearm is vertically bounded, and the upper arm needs to be raised from 1 to 2 when the small arm is closed, and the upper arm needs to be lowered from 2 to 3. The purpose is to make the bucket go smoothly. The amplitude of the lifting of the big arm is from the small arm.

The position of the return is decided! This movement takes a long time to practice.

In daily leveling operations, in fact, the section of 2 to 3 is rarely used. Just from 1 to 2 or even shorter, just stop raising the boom, and the soil in the bucket can be thrown out of the trend. These are just the parties to the operation.

Law. The key to leveling is to "see". Inexperienced drivers often can't see that they have dug high or low. They sit in the cab and think it's flat, but it's actually terrible.

Cake! So I suggest, if you are not sure, just step down from the excavator and take a look! You can see it clearly from a few more angles.

There is also to find a few reference points, according to the requirements of leveling, from the point to the surface.

With more practice and more experience, you will naturally be handy! It is recommended that you go to the Summer Muchen Leveling Association to learn! One-on-one online lessons.

Leveling depends on eyesight, and the mentality should be relaxed! If you can find a breakthrough in the uneven ground, then you will also understand what leveling is! You can go to Summer Muchen for help!

can be used, the throttle can't be too small, otherwise the compound action is not easy to do, the key is not to put the sub too fiercely, after a long time to mature, it will be good naturally,

Dig flat personal experience, sit in the cab, collect the small arm and lift the big arm, when the small arm receives the vertical to the ground to lower the big arm, the middle section can also be slightly with a little roll bucket. Look at the left contour angle of the forearm as a straight line, and the vertical line will go down the upper arm as soon as it passes.

The question is complicated! I know it in my heart, but I don't know how to express it! A reminder of one thing is mentality! The mentality must be stable and flat! This is what the Summer Muchen Excavator Leveling Association taught me!

When I came out of school, I had no work experience at all, except for a useless ID! After several twists and turns, the technology still can't go up, thanks to the summer dust, I can stand on my feet!

The actions used for leveling are the same, mainly to determine the benchmark, stand on the site ** look around, you can see what is uneven

General Tips:

1. Homogenize the soil, backward walking method, the large and small arms should be stretched out to the appropriate position, the bucket back and the ground are at an angle of 30 ° into the soil, according to the tightness of the soil, determine the speed of the small arm, and carry out the composite roll bucket according to the amount of soil in the bucket, and then carry out the rotation of the material.

2. Flat field First use a bucket to evenly spread most of the soil, and use the bucket tooth hook to flatten. Then the bucket back of the bucket is parallel to the ground, keeping the ground almost in contact with the bucket back, extending the forearm, unrolling the bucket, lifting the boom in a continuous compound action, and also using the rotation to sweep away the excess soil and walk backwards.

For details, you can refer to the excavator operation manual.
