12-ton used excavator recommendation 4 models with perfect balance of performance and price

​​​​​​​　　12-ton excavators are very mainstream models, with advantages such as convenient transportation, multiple types of work, and low prices. In particular, classic used excavators are very reliable except for the appearance damage. Usually, the price is 10.000-30.000 US dollars. The longer the factory date and the longer the working time of the excavator, the cheaper the price. Some old models such as CAT312C, Komatsu PC120-6. Hitachi EX120-5. Kobelco SK130-6. etc. are basically eliminated, and the price is very cheap. Some good performance can also be found, but the risk is relatively high. We still don’t recommend it without professional technicians. TD must conduct strict testing and maintenance on each excavator, and unqualified TD will not be sold to the outside.

　　The mainstream used excavator models are also export models, such as CAT312D/D2. Komatsu PC120-7/8. Komatsu PC130-7/8. Hitachi ZX120-5 series, Volvo EC140 series and Kobelco 140-8 series. These models are relatively recent, especially the previous generation of direct injection engines, which can be purchased at around US$15.000. Although the comparison of excavator parameters is not very meaningful, it still gives you an intuitive reference to the specification information.Tiedou

　　Performance characteristics

　　Powerful & low fuel consumption engine: The use of an intercooler with excellent combustion efficiency helps to achieve the best match between power and fuel efficiency. Through the perfect combination of HIIOS hydraulic system, the engine speed is optimally controlled, thus effectively reducing fuel consumption

　　The automatic acceleration function reduces fuel consumption: by operating the joystick, the engine speed is controlled, and fuel consumption is reduced during light-load operations such as leveling and finishing

　　Walking force and rotation force: the rotation and squeezing performance is improved, and the rotation performance of slope operations is improved

　　The rapid switching of working modes under different working conditions: powerful excavation, leveling and fine operations can be performed, and the attachment mode can be combined with the hydraulic breaker to adjust the oil volume

　　The pursuit of reliable durability: the front end parts use HN bushings, the thickness of the bucket rod is increased, and the four sides are reinforced with reinforcement plates, and the bucket connecting pin is filled with grease through the support

　　Equipped with CRES (central pillar reinforcement structure) cab: the central part of the cab adopts a cross-section closed structure pillar, which improves the overall strength and rigidity of the cab and ensures higher safety

　　There are many factors in the selection of used excavators. Don't choose because of a little advantage in the performance parameters and specifications of the excavator. You should consider the purchase of accessories, technical services, and maintenance of the brand in your country. For users who consider the rate of return, it is best to choose previous generation products with mature technology and good reputation, which can save a lot of expenses on subsequent repairs and maintenance.
