What size excavator do you have?

The largest excavator is TZ-22. Is the world's largest bucket excavator, produced by China Taizhong Group, with equipment as high as 22 meters, equivalent to the height of an eight-story building, with a total weight of 1400 tons, equivalent to the total weight of 70 railcars, and a bucket capacity of 56 cubic meters. It is not only the largest in China, but also the largest in the world, which can meet the mining conditions of all open-pit mines in the world today.

A, domestic excavator size distinction general standard

At present, several mainstream second-hand excavator sales platforms in China will divide the machines into different sizes. Among them, small excavators are divided into micro and small. Basically, mini excavators are under 5 tons, and mini excavators are defined as models between 5- 15 tons.

1 and 15 tons are small, and 5 to 8 tons are mainstream models. Small excavators are mainly used in municipal, ditch digging, factory construction, gardens and other working conditions that need careful operation.

2. 15-35 tons is a medium-sized vehicle, and 20-25 tons is a mainstream vehicle, which is also the most widely used among all vehicles. Except for limited working conditions (such as indoor), it can be used in almost all working conditions such as municipal administration, earthwork, road construction, mining and land reclamation.

3, more than 35 tons for big pieces. Choose the model according to the bucket capacity demand. The bigger the tonnage, the bigger the bucket. Generally used for large earthwork and open pit mining.
