The difference between excavators and other construction machinery lies in their versatility, which allows for the installation of a breaking hammer, commonly referred to as a "cannon" by machine enthusiasts; It can also be equipped with hydraulic shears, extended arms, etc., so its price is higher than loaders, cranes, etc.
What kind of excavator is more suitable for blasting? What kind of machine is suitable for firing? One is to consider the price of the machine, and the other is to consider the performance of the machine. It's a bit wasteful to use machines that are too expensive for crushing, while machines that are too cheap may become useless after only a short period of time. From the current perspective, the majority of users use CAT, Komatsu, and Doosan more frequently.

If you want to make money, just buy a cheap car. Doosan should have no problem within three years, and there's basically no need to repair it. If you really don't have money, go straight aheadUsed Doosan 225-7. The price is less than 400000 yuan, and the cost can be recovered in less than two years.
