How to select the suitable excavator
How to choose an excavator ?
Excavators is becoming the most important construction machinery in engineering construction. Many friends who buy for the first time don’t know what model to buy, and what items should be paid attention to when buying. Today we will tell you how to choose one excavator.
1, Project Scale
Excavators can be divided into three categories according to size and capacity: large, medium and small。
A, Small excavator is referred to the capacity below 15 tons, with 5 to 8 tons as mainstream models. Small excavators are mainly used for municipal, trenching, plant construction, gardening and other working conditions that require meticulous operation. Small excavators are divided into micro and small. Basically, micro excavators are below 6 tons, and small excavators are defined as models between 6 and 15 tons
B, Medium excavator is referred to the capacity from 15 to 45 tons, and 20 to 25 tons are the mainstream models, which are also the most widely used of all models. Except for restricted site conditions (such as indoors) that cannot be operated, it can be used in almost all conditions, municipal, earthwork, road repair, mining, wasteland reclamation, etc
C, Larger excavator is referred to the capacity above 45 tons. Choose the model according to bucket capacity requirements, the larger the tonnage, the larger the bucket. Generally used in large earthwork and open-pit mining conditions
2, Purpose of buying an excavator
There are many friends who want to enter the engineering field to start a business, and the excavator has become a basic tool. For these friends, the excavator is a tool for making money. Such demand should be analyzed from two aspects:
A, Have experience and projects. If you have been in contact with this industry before and have ready-made engineering construction needs, then it is very easy to choose, just buy a model that matches the engineering scale
B, Without experience, just want to start a business. The market for large excavators and small excavators is quite completed, and the number of these models on the market is also quite large. The investment amount is large, with hundreds of thousands of millions at every turn. The competitiveness is fierce and there is no industry foundation, so I suggest starting a business with small excavators. Small pressure, easy to find a project, high income, quick payback.
3, Current fund situation
Many friends want to buy a satisfactory model of excavator in one step when consulting on how to buy an excavator. However, the existing funds are insufficient, the project is unstable, and the ability to make up funds in the later period is poor. This situation can only be followed. Perhaps the 85T model is the most suitable, but it might be better to buy a 75T to make money first. The excavator of adjacent models are generally not different too much, so if the funds are limited, you can consider the neighboring models of smaller models.
4, Choice of wheel excavator and crawler excavator
The main advantage of the wheel excavator is that it runs fast, does not require a trailer, low price, and does not damage the road. The disadvantage is poor stability and poor environmental adaptability. It is generally suitable for use in a flat and simple environment. It is not recommended to use in mountain and slope environments. Such as: wheel type KENTE KT85W excavator
The main advantages of crawler excavators are strong stability and strong environmental adaptability. The disadvantage is that they require trailers, are slightly more expensive, and cause serious damage to the road. Just set it directly according to your own construction environment
