Two years ago, the off-line ceremony of the new John Deere E400LC excavator was held in Tianjin. Since then, the mine king of "40-ton excavators looking for rivals" has officially entered the public’s field of vision. It carries John Deere with a rated net power of up to 237kw. PowerTech™ series 9 high-power version of the engine, JD-IHC intelligent hydraulic control technology, four-speed power, three working modes and other advanced functions and technologies, each of which has been a pain point for mine practitioners. For a time, John Deere E400LC appeared in major mining areas, and the roar of this steel beast became the cheers in the hearts of every mine owner.

And now, the new king is enthroned! John Deere's new E400LC excavator is officially dominating the mine!

The new John Deere excavator is designed to serve construction machinery users who are pursuing improved production efficiency and reducing downtime. The realization of this goal is directly reflected in the key parameters of the new John Deere E400LC excavator.

On the basis of maintaining the original advanced performance and technology, the working weight of John Deere's new E400LC excavator is increased to 40.9-41.0 tons, the maximum digging depth is increased to 7000-7400 mm, and the digging force of the stick is increased to 186-203 kN. The bucket digging force is increased to 243 kN, and the capacity of the rock loading bucket and the rock digging bucket have also been greatly increased. The enhancement of key parameters means that the comprehensive work efficiency of John Deere's new E400LC excavator has become more advanced!

It is worth mentioning that John Deere’s new E400LC excavator has not sacrificed its smooth handling and various functions that have already become industry benchmarks by improving key parameters, but has achieved comprehensive progress. For example, John Deere has redesigned an ergonomic, automotive-grade cab for the new E400LC excavator, and provided customers with a touch screen display with more direct control. At the same time, John Deere’s new E400LC excavator has more bucket options and additional auxiliary hydraulic lines, which can provide power for various auxiliary tools to achieve their full potential and help production operations.

The original John Deere E400LC excavator has optimized the boom and stick design for heavy load and rock conditions, and is equipped with a heightened and widened mine-type chassis, a thickened double-tooth track and a rock-type full rail guard , And heavy-duty cooling system, its operational stability can be called the industry's first-class. In addition, in terms of maintenance, the original John Deere E400LC excavator focused on optimizing the maintenance points, making daily maintenance tasks such as various oil level inspections, oil additions, and grease filling faster and more convenient.

While maintaining these advantages, John Deere's new E400LC excavator puts more emphasis on details. It adopts Deere’s unique aviation-grade solid-state electronic circuit, which can greatly reduce the use of wires, relays and sensors on the excavator, making the whole machine more reliable and durable; its configuration can be set to intermittently automatic working high-efficiency hydraulic drive The fan can not only reduce noise and fuel, but also clean the cooler core in reverse. There are also working lights. The new John Deere E400LC excavator is equipped with 7 high-brightness LED lights. From then on, the night is like the day and the production day and night Part-time.

In addition, John Deere’s new E400LC excavator has a newly optimized bucket. While making the bucket more wear-resistant, it also adopts different opening widths, teeth and side edges for different materials and working conditions, making the new E400LC Faced with different working conditions, the excavator can be silky smooth and tear obstacles!

For a long time, every time John Deere introduces a construction machinery product into the Chinese market, it will fully listen to the opinions of domestic users and make targeted adjustments. From prototype manufacturing to landing in the Chinese market, John Deere will conduct extensive tests on the products, and finally launch a mature product that can meet the harsh domestic mining conditions. For this reason, from 2018 to the present, the king of the 40-ton mining excavator in the Chinese market has always been under the name of Dier. Editor/Sang Xiaomei
