Doosan DX420LC-9C Excavator: Enough to be worthy of ownership

As an all-round model for construction of mines and large-scale civil engineering, the DX420LC-9C gains many fans with its powerful performance, high reliability, and comfort.

Doosan DX420LC-9C Excavator

Big heart - using Scania engine, pump nozzle integrated structure and unique centrifugal filter settings, with high reliability, high fuel efficiency, high maintenance convenience, low failure rate, low maintenance costs Features.

Big heart

Low energy consumption - adopting a low fuel consumption design concept with high-efficiency engine and hydraulic components, and adopting an advanced SPC (Smart Fuel Saving) mode to effectively solve the problem of rising costs due to increasing fuel costs and ensure customer benefits .

Low energy consumption

With the largest bucket (2m3) at the same tonnage, it can effectively ensure the working efficiency and the compound operation ability is superior. With the same level of better digging force, walking traction, lifting force settings, effectively improve the operating efficiency. A reasonable amount of fuel is set to ensure a more gentle compounding operation.

Efficient pilot control

Equipped with a new large-capacity, high-efficiency imported hydraulic pump, the operating efficiency is greatly improved. At the same time, a large-capacity gear pump is used to achieve efficient pilot control.

High reliability

Strengthen the design of the size of the arm, the size of the arm plate increased by more than 16% over the previous generation. The new structure design uses a large number of integrated structures to reduce welding, increase the contact area of ​​sheet metal contact, and effectively improve durability. The shape of the arm sleeve and the boring head is optimized to further improve the durability by increasing the force and connecting the contact area.

Reinforced design arm

More reliable weight brackets and a sturdy base plate. The more reliable weight support and the sturdy bottom plate design can easily deal with harsh working conditions to ensure long-term and stable operation of the equipment. The use of 6 fixing bolts and increasing the horizontal spacing of the bolts make the weight bracket more stable and prevent the phenomenon of falling off due to long-term vibration. More solid and strong floor design, long-term protection of the core parts is not damaged, thick cover plate and super durable bolts to ensure its safety and stability.

More reliable weight carrier and sturdy floor

To adapt to poor quality oil products, improve the filtration efficiency of the oil filter system, and increase the wear-resistant, corrosion-resistant material coating for key parts, so that its ability to adapt to inferior oil products is greatly improved.

Comfort experience

The new cab ensures wider vision and quieter spaces, providing drivers with a more comfortable working environment. The new seat adjustment mode is as convenient as a passenger car; the shock-proof suspension seat can be adjusted in both front and rear directions, and the height can be automatically adjusted according to the weight of the driver.

Experience comfort

The car-level air-conditioning system, automatic temperature adjustment, to provide drivers with a comfortable driving environment, reduce driving fatigue; handle ergonomic design, operating comfort greatly improved. Through the high-tech color LCD display system, various information about equipment operations can be obtained, thereby improving the facility management convenience.

Automatic temperature control system, ergonomic cooling and heating air circulation system, to ensure the comfort of operation, through the reasonable setting of the vents, to avoid the risk of frost in winter glass. (This article is from Doosan)
