What size excavators are generally used on construction sites now?

The use of excavators has become very common on modern construction sites. Their size and type vary depending on the needs of the specific project. Generally speaking, the size of excavators used on construction sites ranges from 15 tons to 30 tons. An excavator of this size is adequate for most construction and earthmoving needs.

First of all, we need to understand that the tonnage of an excavator refers to its working weight, which is the weight of the excavator itself plus the maximum weight it can lift. This parameter is very important for evaluating the performance of the excavator. The larger the tonnage, the more powerful the excavator is typically and can handle heavier materials and larger workloads. However, larger excavators are not necessarily suitable for every job. For example, a small excavator may be more suitable on some construction sites where space is limited or where delicate operations are required.

When choosing the size of an excavator, contractors often base their decision on the specific needs of the project. For example, if it's a large-scale earthmoving project, a larger, more powerful excavator may be needed to work more efficiently. And if you are doing detailed excavation work, such as digging a basement or trench, you may need to use a small excavator.

In addition, the brand of the excavator is also an important factor in selection. Foreign brands such as Caterpillar, Komatsu, Hitachi Construction Machinery, etc. enjoy a high reputation in the field of excavators, and their products usually have excellent performance and quality. However, the prices of these foreign brands are usually higher than those of domestic brands. Domestic brands such as Sany Heavy Industry and Zoomlion also provide excavators with good quality and relatively more affordable prices.

When choosing an excavator, in addition to considering its size and brand, you also need to consider its fuel efficiency, maintenance costs, ease of operation and other factors. These factors will affect the overall cost of using the excavator, so comprehensive considerations need to be made when making a choice.

In general, the size of the excavator used on a job site varies depending on the needs of the project. When choosing an excavator, you need to comprehensively consider factors such as project requirements, excavator performance, brand, and price. Only by choosing the most suitable excavator can we ensure the smooth progress of the project, maximize work efficiency and reduce costs. At the same time, with the continuous advancement of technology, future excavators may be more intelligent and efficient, providing better support for engineering construction.
