15-ton excavator recommendation: 5 used excavators that are easy to use and inexpensive

　　For users, the 15-ton tonnage model is mainly aimed at individual users. Projects with larger projects or longer construction periods generally use excavators of 20 tons or more as the main models. 15 tons is too large for most individual users. It is obviously not suitable for family use. 15 tons is mainly used in unexpected areas of the city. Especially for road construction or renovation, the work efficiency and size specifications are very suitable.

　　Except for the Caterpillar with a deadweight of 17 tons, the other four models have a basic net weight of about 15 tons. The bucket capacity is 0.5-0.6m³, of course, it can be matched with different accessories to meet different work needs. Especially the breaker for breaking the road surface, as well as hydraulic pliers and other tools. The current reference price of these used excavators is: 25.000-45.000 US dollars. The price is not high but you can own a medium-sized crawler excavator with very good performance, and the later benefits are very lucrative.Tiedou

　　Heavy-duty large and small arms: Install heavy-duty large and small arms with better durability, use cast steel products to improve strength, and increase the durability by 1.5 times. The thickness of the lower support ring is increased, the welding strength of the frame is increased by 20%, and the structure is more stable.

　　Cooling system: A large-capacity, high-efficiency cooling direct-connected fan is used, and the sealing sponge of the cooling module uses a polyurethane sponge with higher heat resistance, which effectively improves the cooling performance.

　　The performance gap between the above 5 used excavators is not large. In addition to considering the price, it is also very important for users to choose whether there are local parts sellers. Tiedou can provide more than 99% of various types of excavator parts, but considering the long cross-border transportation cycle, it is generally recommended to purchase non-core parts in your own city as much as possible.

　　Tiedou also provides different types of excavator parts and various maintenance parts. At the same time, the appearance can be repainted according to the needs of users to meet the needs of different customers. For the need to modify the excavator, especially the modification of the excavator arm extension, the modification of the excavator chassis and the installation of special excavator parts, it needs to be customized in advance.
