How does a mini excavator dig trenches?

Small excavators have a large output and high efficiency. The excavator should be selected according to the size of the project and transportation conditions. How to use a small excavator to carry out trenching work? Let's take a look together below.


1. Before digging the trench, do a good job of straightening the line to avoid the problem of digging deviation. Digging trenches should be straight. This is a very important principle in the process of trenching. In order to avoid digging deviation, a straight line is usually set in advance with lime on the construction site. The center line of the chassis of the small excavator is aligned with the lime line, and the middle of the bucket The bucket teeth correspond to the lime line, which can avoid digging deviation.


2. According to the different functions of the ditch, carry out different treatment work on the ditch. If the function of this ditch is to facilitate the installation of water pipes, it needs a certain slope at the bottom; if it is a house foundation pit, the bottom is required to be level.


3. Do a good job of leveling the slope. The principle of flatness is an important factor to ensure that the ditch will not collapse. In the process of digging the ditch, from the beginning of the V-shaped ditch to the back, the slope must maintain the same slope. Of course, the soil quality and the depth of the ditch are different, and the slope is also different. It needs to be adjusted accordingly, and the slope is guaranteed, so as to better ensure the trenching effect.

Causes of crawler excavator pipe burst

Crawler excavators are very common in our life, but in the process of use, pipe bursts often occur, so what are the factors that cause this phenomenon? The following crawler excavator manufacturers will give you a detailed explanation: 1. Use inferior hydraulic pipes For the sake of cheapness, many people choose inferior crawler excavator hydraulic pipes that do not meet the standards. The performance and reliability of the hydraulic pipes are far lower than the original pipes, and the sealing and reliability cannot be guaranteed. After a period of use, fuel consumption and even oil leakage will occur. Therefore, it is necessary to choose an ordinary big brand product to replace the hydraulic pipe. 2. Excessive pressure in the hydraulic system will increase the possibility of bursting. This method is used to test the pressure and various actions generated by the main pump. If it is confirmed that the pressure value is too large, the pressure of the multi-way valve can be appropriately ...

Precautions for leveling the ground with small excavators

Leveling a small excavator is one of the skills that a driver must master, and it is very important to master certain essentials of action. This article provides a theoretical basis for novices. Let's take a look at what knowledge a small excavator operator needs to have when leveling an excavator. Essentials of excavator leveling action: 1. On the land to be leveled, first visually measure the height of both ends of the ground, then find the elevation point from the high end of the ground, level it in turn towards the low-lying end, and finally dig out the soil higher than the elevation point and fill it up. In low-lying areas, it is visually level. 2. When the excavator lowers the boom, open the second arm until the angle between the boom and the boom is about 45 degrees; open the bucket so that the mouth of the bucket and the boom of the second arm are basically in a horizontal state; the bucket falls to the ground and retracts the second arm, lift The big arm pulls the soil bac...

Excavator maintenance method

Thank you very much for your question. The following is the relevant information about the maintenance method of the excavator. daily cleaning During the use of the excavator, it will be eroded by a large amount of dust, mud, sand and other impurities, which will accelerate the wear and corrosion of the machine. Therefore, in order to prolong the service life of the excavator, daily cleaning is very important. Specific methods include: Use a high-pressure water gun to clean the surface of the machine, especially the inside of the machine and the surface of the radiator. When cleaning the radiator, care should be taken not to point the high-pressure water gun directly at the radiator chip to avoid damage. After daily use, the machine should be cleaned and inspected briefly to ensure that the machine is in good working condition. Lubrication and maintenance Lubrication maintenance is an important part of excavator maintenance. Improper lubrication will lead to parts wear, oil leakage and...

Excavator service life

It is our pleasure to provide you with information about the service life of excavators. First, the service life of an excavator depends on several factors, including but not limited to the following: Use environment: The service life of the excavator will vary greatly under different use environments. For example, an excavator will last longer if it is used in a dry, clean environment than if it is used in a wet, messy environment. Maintenance: Regular maintenance and repair of the excavator can effectively prolong its service life. If maintenance and repairs are neglected, various parts of your excavator may suffer damage or wear, shortening its lifespan. Frequency of use: The frequency of use of the excavator also has a great impact on its life. If heavy work is performed regularly, the various parts of the excavator may wear out more quickly, shortening its lifespan. Generally speaking, the service life of the excavator can reach more than 5000 hours. However, the specific service ...
