Tiedou Liebherr used excavators (Issue 5) R992 Litronic, R992E, R998 SME Litronic Litronic, R 998 SME E parameter configuration and specification information comparison

　　The last issue of Liebherr standard and special equipment excavator equipment introduction. This issue introduces four excavators for user reference and suggestions. Tiedou only has replacement models and no Liebherr excavators above 90 tons are available. When the excavator equipment weighs nearly 100 tons, it is difficult to see them outside. The huge body and powerful performance make Liebherr R992 or above models mostly work in mining areas or mountainous areas.

　　R992 Litronic/E

　　The two models are the same, but there are differences in the type of work. The 992E has an engine power of 400Kw and the R992 Litronic has an engine power of 420Kw. However, the 992E is heavier than the standard R992 Litronic. The main reason is that you can tell from the pictures that the 992E uses a front shovel to work. The length and structure of the boom and dipper are different from the design and use mode of the standard backhoe.

　　The front shovel excavator bucket faces outward, which is used for engineering operations higher than the excavator height, especially in rock, mineral, mountain and other projects. It has a very distinct advantage in the perfect use of the working design, and has a very strong processing ability to handle hard ground mines and solid mountains. In terms of efficiency, the front shovel has the same excellent working ability, especially in terms of loading capacity, the design of the front shovel can quickly and effectively carry out filling work.

　　The disadvantages are also obvious. For work below the height of the excavator equipment, the front shovel is not competent. Due to design reasons, it is difficult to complete complex work in underground channels. Secondly, the front shovel excavator equipment cannot adapt to the backhoe excavator for the installation of accessories and auxiliary tools. Customization and modification are usually required. In addition, the size and weight of the front shovel with the excavator are large, and the manufacturing and maintenance costs are very high. At the same time, the operation is obviously different from the backhoe. The operator needs a certain amount of time to adapt to the model or relearn.

　　R998SME E is a medium-sized excavator specially designed for large-scale mining. It weighs more than 100 tons and has an engine power of 400Kw. It is a standard hydraulic crawler excavator with a bucket capacity of 5.20m³-7.20m³, which is a behemoth among excavators. Liebherr currently has many excavators over 100 tons and is still active in work. These equipment usually need to be purchased through customization, with a long cycle and very high prices.

　　The above models are highly targeted at the types of work. We have already said that we do not have the same products for sale to you. We provide alternative models. The models currently sold in the European region of Liebherr are still very reliable. The manufacturer provides comprehensive and complete after-sales service. The cost of later maintenance of such large equipment is very high. However, for used excavators, the second-hand value retention rate of super-large excavators is not high. At present, the price of similar models in Tiedou is usually only about 30%-50% of the new machine. The factory date of some parts is longer, but the working time is generally shorter. The performance is very good, which is very cost-effective for users with budget control requirements.

　　Tiedou used excavator trade network covers many used excavator sales cooperation channels around the world. In addition to the single purchase of used excavators in China, Japan, and South Korea, the local joint venture and China-made excavators have very good reputation and use conditions in the market. The test of the excavator requires 21 manual and equipment tests to ensure that the user can purchase the excavator for stable and reliable use. If your budget is unlimited, then we strongly recommend Liebherr large excavators. Although the price is high, it must be your biggest helper in terms of excellent performance and long-term market reputation.
