Tiedou Liebherr used excavators (Issue 2) R926 Litronic, R928 Litronic, R930 Litronic, R930 Tunnel Litronnic R934 Litronic, R938 Litronic parameter configuration and specification information comparison

　　Liebherr's official new six medium and large excavators on sale basic performance introduction. Some of the six models in this issue have no sales channels in some countries. First of all, from the data comparison, it is not difficult to find that the performance of several Liebherr models is very powerful. The R926 series has a core power of 26 tons of engine with a weight of 150Kw/204Ps, which is also a very powerful performance data in the same class. The bucket capacity of 0.55m³-1.75m³ is selected for installation and use in different types and pressure sizes.

　　Five of the six models are standard hydraulic crawler excavators. The only difference is the R930 Tunnel Litronic, which has an engine power of 129Kw/175Ps and a deadweight of 33 tons. Is it not enough to have such a small power? But if you see the equipment, you will find that it is very different from other excavators. This is a Liebherr tunnel excavator, which has not been found in other excavator manufacturers.

　　Although many excavator manufacturers currently have many choices in the manufacture and model of short-tail excavators, you will find that Liebherr has spent a lot of effort on this R930 Tunnel Litronic, which can work in tunnels of 4.75-7.5m. Because I haven't seen the actual machine, I only observe the bucket capacity of the excavator from the picture. 0.3-0.6m³ Considering the particularity of tunnel work, this bucket is very different from our common buckets. Of course, if it is just excavating earthwork, I think we don't need it at all. The entire dipper arm and boom of the excavator are fully covered and effectively protected, which can easily cause damage to the cylinder in the tunnel environment.

　　The horizontally movable arm device has a full-wrapped design for fragile management. It is not difficult to see Liebherr's intentions and attitude on this excavator. The excavator adopts a short tail design, which is also an important condition for convenient rotation and work in the tunnel. The chassis is equipped with a hydraulic pusher and the cab is fully protected to effectively improve the safety of the operator.

　　Careful users will find that the boom height and size of this model are very different from the standard version. The boom of the entire excavator is only slightly higher than the cab. This design is mainly to work in tunnels with limited height without affecting the limited work of the boom linkage arm. For the boom lateral movement device, it is similar to the micro-excavation design at the bottom of the boom. The hydraulic movement of the boom direction. This type of work is still in the tunnel. The working direction can be moved under special working conditions and angles to meet the work requirements.

　　All kinds of details reflect the strength of Liebherr's R30 series. The same conventional version R930 series has a powertrain of 180Kw. In the comparison of models and weights, Liebherr's overall engineering machinery quality will be slightly higher than other excavator manufacturers. Although weight is not the most important, it also means cost and equipment materials.

　　R934/R938 series are also standard large hydraulic excavators. Several models with power of 220Kw-220Kw have been launched on the market for 2-4 years. After market testing and user feedback, they are worthy of recognition. We will list the mechanical models at the bottom of the article for everyone to compare. If there are information errors in the table, please provide correction information for us to make later modifications. Part of the information comes from the official website and part from the Internet.

　　For users who like Liebherr excavators, its entire excavator product series has excellent performance in the market, and the price retention rate of used excavators in the market is stable. Tiedou used excavator trade network provides Liebherr series excavators that are not only cheap, but also provide 3-12 months of large-scale warranty service. Today, the parameters and configurations of the 6 models introduced can be easily purchased except for the R930 tunnel excavator.

　　On September 8. 2024. the exchange rate of the US dollar against the RMB continued to decline. The price of the existing used excavators for sale on Tiedou Used Excavator Network remained unchanged, but the transportation costs and other costs may fluctuate, but the fluctuation ratio is not large. For the performance and other issues that users are most concerned about, we will conduct detailed tests on the equipment and welcome users to come to the site to test the excavator in person.
