Recommended popular excavators: 8 large 40-50 ton used excavators recommended

　　Excavators above 40 tons usually do not work in cities. The very large volume and working range radius also mean that excavators above 40 tons mainly work in large engineering projects. If you need such a device, how should you choose? Around 2020. many excavator manufacturers have launched new large hydraulic crawler excavators on the market. Although the price is slightly higher, it is very good in performance, fuel economy, and energy saving and emission reduction. But there are still many users who choose used excavators.

　　There are two main advantages of used excavators:

　　1. Cheap price. For 40-50 ton excavators, although the price in each country will be different, considering different excavator manufacturers, the basic reference price is about 250.000-350.000 US dollars, while the price of used excavators is generally 60.000-150.000 US dollars, reducing the capital investment by 40-75%. But the cheap price also means that you cannot enjoy the warranty service brought by the new machine manufacturer.

　　2. Diversified choices. In addition to the wide selection of brands, some excavator models have been tested by the market and are stable and reliable, which are loved by everyone, especially in some countries. The reason why used excavators are more popular is that the simple structure also means that the excavator is easy to maintain and repair. The new excavator is equipped with a lot of technology, which also means that it is difficult for individuals to solve it without maintenance equipment. The high cost of purchasing accessories also makes many people hesitate about how to buy.

　　Today, TD will introduce 8 best-selling excavators, with sufficient inventory and low prices, and provide up to 1 year of after-sales service for vulnerable maintenance accessories to reduce the cost of use. The used excavators sold have been strictly tested by us, and you can buy and use them with confidence.
