DEVELON construction machinery manufacturers may be unfamiliar to some people, but when it comes to its predecessor, DOOSAN, it will not be unfamiliar. This is a sub-brand launched by Hyundai and Doosan in South Korea. It also replaces the market demand and positioning of the original DOOSAN, and the goal is to build DEVELON into a new generation of construction machinery manufacturing companies. The roots of both come from South Korea. DEVELON first appeared at the 2023 Las Vegas International Construction Machinery Exhibition (CONEXPO-CON/AGG Exhibition) in the United States.
In the next few issues, we will introduce DEVELON brand construction machinery products in detail. The first one to introduce to you is still the Mini excavator. Among the 6 Mini excavators, we can clearly see the figure of its predecessor DOOSAN brand from the appearance. The whole machine is matched with two main colors of gray and orange. In terms of appearance, the lines of several Mini excavators are very tense. In addition to providing better heat dissipation, the hollow heat dissipation net gives people a more powerful feeling as a whole.
Among these five models, the DX19-7 comes standard with a cockpit, which also provides a good working environment outdoors and in bad weather. Of course, the DX19/DX20 series can choose a cockpit and air conditioning, which gives the operator a more comfortable working experience in outdoor environments. The five chassis are all equipped with a hydraulic retractable structure as standard, which can have better passability through narrow sections, and can be freely moved for short distances without damaging the road surface with rubber tracks.
From the parameters of the DX20ZE series, you can see that this is a pure electric excavator. The appearance is not much different from the conventional version. It is equipped with a 20.4Kw battery inside, providing a standard voltage of 220V, and it only takes 8 hours to fully charge. And through fast charging, the charging work can be completed in up to 1.5 hours. This model has achieved zero carbon and pollution emission problems. In addition to not requiring fuel, the noise of the machine itself is extremely low, which is highly recommended for community work.
DX20Z-7 is the only one among these excavators that uses the Yanmar 3TNV70 engine, which is currently used in many similar models. The engine has a maximum power of 10.6Kw and a speed of 2200 rpm. The balance between environmental protection and performance can also bring out the powerful performance of the excavator.
The three models of DX10/DX17/DX19 are equipped with Kubota D722/D902 engines with stable performance. In actual tests, these two engines have low noise, stable performance output, and excellent fuel economy. The hydraulic pumps that everyone cares about are uniformly equipped with DOOSAN hydraulic pumps. The market test is enough to prove the stability and reliability of this hydraulic pump.

Tiedou used excavator trade network provides two options, DOOSAN series and new DEVELON series. It seems that like other brands, the sales models of Mini excavators in China are scarce. If you need a DEVELON excavator, you can consult the local dealer for Mini excavators, but you can choose more Japanese or Chinese Mini excavators in Tiedou. The price is cheap and the performance is also very reliable.
The official reference price provided will fluctuate according to the selling price, value-added services and tax policies of different countries. For specific prices, please consult local/national dealers. If you are looking for a lower price, then DOOSAN is a very good choice. At present, you can choose a used excavator with excellent performance at a market price of US$10.000-20.000.
