1. After the construction worker releases the elevation, he must first see clearly the flatness of the site and mentally form the shape of the site after it is flattened.

2. Consider the softness of the soil and be aware of it. To loosen the soil, we need to raise it a few centimeters higher. In this case, it will just reach the elevation after being pressed, and vice versa for hard soil.

3. Be aware of the choice and use of buckets. Since there are no bucket teeth, this type of bucket is mostly suitable for excavation and leveling operations in soft soil and materials. Machine owners who have the conditions can modify it by themselves and use this type of special bucket.

4. The excavation range also needs to be flexibly grasped during operations. When leveling a large area, the excavation range can be maximized while meeting the leveling requirements. If the leveling quality requirements are high, the excavation range can be maximized. Narrow it down to the appropriate range. In addition, the direction of travel of the excavator should be "planned". It is best to keep the excavator traveling in a straight line and minimize the time spent on turning and repeated work scope.

5. When we start leveling at one end, we must first stop the excavator and choose a reasonable reference object. During slope leveling operations, we often need a reference object and a driver with rich driving experience. The driver can judge the quality of leveling based on the reference object without having to stop and get out of the car to observe, thus saving time.

6. The excavator windshield will affect the operator's line of sight to a certain extent. If it does not affect the operation, it is recommended to pull up the front windshield and open the doors and windows to obtain a better line of sight. If possible, you can get out of the car and observe more often, so that you can know what you are doing and adjust the excavation plane in time. In addition, the height of the excavator platform will also affect the operation accuracy. Most operations will require leveling while loading. At this time, without affecting the loading efficiency, the excavator platform should be lowered or raised to keep the excavator at a Reasonable height.

Pay attention to the use of attachments. Most small excavators are equipped with a dozer blade. When leveling soft soil, the dozer blade can be used for "preliminary" leveling. It can also be used to "build roads" and then perform fine leveling, killing two birds with one stone.

Extended information:

An excavator is a special engineering vehicle that consists of a rotating platform, a large shovel and a mechanical arm. It usually travels on tracks or wheels. Because of its special appearance, it has various names in the industry, such as monster hand, backhoe, excavator, etc. Judging from the development of construction machinery in recent years, excavators have developed relatively rapidly, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator: operating weight (mass), engine power and bucket capacity.

Uses of excavators:

Backhoe operations: Backhoe operations are generally performed below the ground, mainly for excavation.

Forward shoveling operation: Front shoveling operation is generally carried out above the ground, and the rotation mode of the bucket is opposite to that of back shoveling. Use stick hydraulic cylinders to scrape the ground. The digging force during front shoveling is smaller than that during back shoveling.

Trenching operation: By configuring the bucket corresponding to the width of the trench so that the crawlers on both sides are parallel to the edge of the trench to be dug, the trenching operation can be carried out efficiently. When digging a wide trench, dig the sides first and the middle last.

Loading operations: When performing loading operations, the excavator should be moved behind the loading truck first to prevent the bucket from hitting the truck cab or other personnel during rotation. Moreover, it is more difficult to move the excavator behind the truck than next to it. Easy to load. It is more convenient to load the truck from front to back when loading, and the loading capacity is large.

Level the ground: Fill and level the ground first, and move the bucket back and forth in a horizontal manner. When the excavator is moving, do not use pressing or shoveling to level the ground. Level the ground forward from the front of the excavator, then gently pull the arm and slowly raise the boom. When the arm exceeds the vertical position, first lower the boom slightly, and then operate the machine so that the bucket moves horizontally move.
