Buyers who choose small used excavators will have many choices. With so many brands and models, how to achieve a relative balance between price and performance. Today, TD recommends three 7-ton small excavator equipment with the most exports and consultations. The new models are not cost-effective, especially for developing countries. The equipment maintenance cost and price increase the cost of use for buyers. In addition, some old equipment is cheap, but the working time is long. If there is no professional engineer to accompany the equipment, there is no way to guarantee the stability and reliability of the equipment, and the cheap old excavator also means an increase in the failure rate.
The three 7-ton excavators recommended today have achieved a relatively perfect balance between price and performance. These three models are 3-5 years old and have a working time of 2000-7000 hours. For an excavator equipment, the performance is still at its peak, and each excavator equipment has been strictly tested and maintained by us. Eliminate the problem of the core components of the excavator.Tiedou
