Crawler excavator SDLG E6210F – Chinese equipment almost from Volvo

Crawler excavators have always been in demand in the construction services market. To people who are not familiar with the nuances, it seems that such a technique is outdated. They believe that these are all relics of the past. A tracked chassis is suitable for tanks, but modern excavators should be on wheels.


But in fact, it is precisely this technique that is ideal for working in difficult conditions. For example, on slopes it remains stable and does not slide down. This is due to the impressive mass of the tracked chassis and its width.

In such a situation, the excavator can be easily moved. But equipment with pneumatic wheels needs outriggers. But it is difficult to use them on a slope. Therefore, crawler excavators have no competition here.


Today we will look at equipment performing in the 20 ton class. We will talk about a Chinese-made excavator from Shandong Lingong Construction Machinery. The model is called SDLG E6210F.

Brand History

In Russia and other countries, Chinese technology is traditionally considered not very reliable. This opinion still prevails today. And somehow it is overlooked that many global brands have been producing their equipment in China for a long time. And no one is stopping companies from the Middle Kingdom from copying it or even working a third shift at the same plant.

Shandong Lingong Construction Machinery (SDLG) was founded in 1972. For about 20 years it produced equipment, often copied from Soviet ones, and was practically unknown outside the Middle Kingdom.

But in 1994, a significant event occurred - the construction of a joint plant with the Japanese company Komatsu to produce hydraulic excavators.


Equipment under the SDLG brand has proven itself in the market from the very first years. It was distinguished by a number of features:

✅ Use of Japanese components and assemblies
✅ Quality of workmanship
✅ Conditionally affordable price

The dynamically developing company attracted the attention of the Volvo concern. In 2006, a controlling stake of 70% was bought by the Swedes. This has made SDLG's construction equipment even more diverse and of higher quality. Volvo simply cannot afford to produce cars that do not live up to their status.

Technical features

SDLG E6210F is a 20-ton crawler excavator of the 4th size group. The equipment is capable of working with soils from the first to fourth categories. It is possible to use an excavator for rocks, but only previously blasted ones.


The standard bucket included in the kit has a volume of one cubic meter. The manufacturer also offers other, more specific equipment.

There are buckets:

✅ Rocky
✅ Trench
✅ Large
✅ Small

The excavator is 9,7 meters long. Its ground clearance is 460 mm. But you need to understand that this is a tracked vehicle; it is capable of literally crawling over difficult terrain. The total operating weight of the SDLG E6210F is 20,7 tons.

The buckets offered by the manufacturer vary in volume from 0,85 to 1,2 m3. But this does not mean that only they can be used in the process of work.

The engine of the excavator is German – from Deutz, but it is assembled in the Middle Kingdom. The fuel tank is designed for 350 liters.

The key feature of SDLG technology is the power units. They are always from well-known global manufacturers, but assembled in China. The E6210F excavator has a German Deutz engine.


The engine is turbodiesel with a volume of 6,1 liters. Its power will surprise motorists. There are only 167 liters. With. And this is in the presence of a turbine. But you need to understand that this is a power unit for an excavator.


The engine weight is impressive - 500 kg. The manufacturer specially installed it on a turntable so that it acts as a counterweight to the excavator boom.

Гидравлика

The main hydraulic pump in the SDLG E6210F system is two-section. This unit is from the Japanese company Kawasaki with the index K3V112DT. The hydraulic pump is not assembled in Japan, but not in China either. He is of Korean descent. Each of the two pump sections has a capacity of up to 200 liters per minute. As a rule, this is enough.


There is also a gear hydraulic pump for the control circuit. If its power is not enough, then working pressure hydraulic cylinders are used.


Main hydraulic valve from Toshiba. The motors used for the undercarriage tracks are from Nabtesco. This is also a Japanese brand.

The brakes are multi-disc - they operate in an oil bath. The tracked platform is based on a special powerful X-shaped frame.

Features of the equipment

Excavator SDLG E6210F with cast elements welded into the boom. This scheme occurs in premium technology. This is another advantage of the Chinese model, which is why Russian clients choose it. Cast elements are much stronger than stamped ones. Therefore, they can withstand not only the designed loads, but also their excess.


The SDLG E6210F excavator is capable of digging holes or pits up to 6,7 meters deep. Operating radius – up to 10 m.

Customer Reviews

Most often, construction organizations buy the SDLG E6210F in Russia. They are especially popular among road workers. The weight of the excavator allows it to be used as a leveler.

The SDLG E6210F easily climbs and works on slopes. During operation, excavators of the Chinese brand prove to be reliable and trouble-free. One of the main advantages is the equipment purchased from official dealers.

That's why it comes with a warranty. Moreover, the repair of excavators in the process is not just free. Masters from company centers themselves go to the location of the equipment with all the necessary equipment.

If it works, the problem is fixed immediately. If not, the necessary parts are quickly ordered, after which they are installed.


Excavator operators who managed to work on the SDLG E6210F speak positively about it. The technology has enough power in any situation. Nothing surprising - the engine is a Deutz brand, albeit made in China.

In principle, professional excavator operators are more concerned about another issue - the convenience of long-term work. There are no complaints about this either - the cabin of the SDLG E6210F is spacious. It has high-quality noise and dust insulation.


As practice shows, with a thousand operating hours, the SDLG E6210F excavator only needs standard maintenance. This is an oil and filter change. What is noteworthy is that these operations are usually performed by representatives of dealership centers. Not free, of course, but you don’t have to worry about the quality of the work. And the excavator will not be removed from the warranty.


To summarize, it is worth noting that the SDLG E6210F has managed to establish itself positively in Russia. The technology meets international standards. The “hand” of Volvo is felt in everything.

The only serious disadvantage of a crawler excavator weighing more than 20 tons is its transportation. To do this, you not only have to call a specialized tractor-trailer, but also obtain permission.

In general, the successful sales of SDLG E6210F excavators in Russia speak for themselves.
