There are many excavator products in the construction machinery market, and various models are updated alternately. Many friends are confused about how to distinguish these crawler excavator models. Crawler excavator is a common construction machinery, which can be divided into many different types according to its use and performance. Here are some common types of crawler excavators:
Small crawler excavator: suitable for small projects such as urban construction, landscaping, and farmland water conservancy.
Medium-sized crawler excavator: suitable for medium-sized projects such as road construction, mining, and river improvement.
Large crawler excavator: suitable for large civil engineering, tunnel construction, hydropower station construction and other large projects.
Long-arm crawler excavator: suitable for projects that require deep excavation or long-distance operations, such as deep foundation pit excavation, river dredging, etc.
Super-large crawler excavator: suitable for super-large projects under special circumstances, such as open-pit mining in mines, dam construction, etc.
The above are only a few common types of crawler excavators, and different brands and manufacturers will have different classification methods and naming rules.
Excavator track material:
The track of the excavator is steel track. Relatively speaking, the range of use of steel tracks and their service life, as well as the selection of working conditions are wider. The working condition of the crawler is harsh, so it must have sufficient strength and rigidity, good wear resistance, and light weight to reduce the consumption of metal and reduce the dynamic load when the crawler is running. The track and the ground must have good adhesion performance to ensure sufficient traction, and consideration should also be given to reducing driving and steering resistance.
There are two types of tracks. One type is made of hard material and assembled from many small segments; the other type is formed in one piece and made of soft rubber-like material. The former can be used for heavy vehicles, but the weight and noise during driving are relatively large, while the latter has low weight and noise, but can only be used for light vehicles.
