conclusions

There is no clear definitive conclusion. The Liebherr caterpillar excavator photo, which is posted on the Internet, on the one hand, is a powerful "sumo wrestler", on the other, a "slow leisurely turtle." Although slowness brings out the best technical capabilities excavators from German manufacturers. Market positions are clear, priorities are set. The only way to modernize and improve technical characteristics remains.

All manufactured excavator equipment of the German manufacturer Liebherr has many advanced technological solutions and innovative developments, whereby this brand can be called one of the leading ones. In the process of product development, for the most part, only professional employees with quite a lot of experience are involved, which just explains the increased quality of the machines. Nowadays, the world market is represented by a huge number of various modifications and basic models having similar equipment and differing technical characteristics.

Description and features

One of the models in the excavator line is the Liebherr 944 crawler excavator. It is worth noting that compared to other German cars, this model is not so popular in the world market of special equipment. But high demand yet the model is available on Russian market, because it has not the largest overall dimensions, which in turn allows you to work in conditions with a small working space.

This excavator, like most other models, is able to withstand very extreme conditions operation. All parts of the machine, systems and components provide maximum trouble-free operation even at temperatures from minus 40 degrees Celsius to plus 65 degrees Celsius, due to which the equipment is especially in demand when working in the northern regions of Russia. Not all similar models can stand out with this indicator, which makes the technique one of the best in Russian conditions operation.

Thanks to its reinforced design, the Liebherr 944 crawler excavator is able to cope with increased loads. Additional options include installation various types running platforms and attachments. All this gives the consumer the opportunity to choose optimal configuration excavator capable of performing certain types of work. Of course mass production of this excavator takes place in Germany at specialized enterprises of the brand, which additionally provides not only high quality, but also increased reliability, which is simply necessary for such equipment.

The model has an elongated boom, which is much longer in size than the model itself, which became one of the key features. But, it would seem, with such equipment, the equipment is most prone to tipping over, however, the manufacturer solved this problem through the well-thought-out design of the caterpillar platform. Thus, a third of the load on the bucket is transferred to tracked chassis, which, together with the rear counterweight, provides excellent stability and allows the excavator to work with fairly heavy loads.

Standard equipment crawler excavator The Liebherr 944 includes a high-performance air conditioner, which is controlled via an idle control sensor. In addition, the equipment is equipped special system, which provides increased stability when operating on uneven surfaces or on rocky soils. The metal used in the design of the model has an increased thickness, which, together with paintwork guarantees reliable protection from corrosive processes.

In its class, this model has become one of the best for the most part thanks to unique features, which in this model is more than enough. Also, all this provides equipment with a quick payback, which is especially important in small construction organizations.

A distinctive feature of the whole design of the model is quite low level centralization of gravity, due to which a certain proportion of the mass is transferred to the tracked platform, which allows the equipment to withstand very heavy loads without any problems. It also has a positive effect on the performance of the excavator. Another advantage of the design is the ability to perform any operations with rocks and other materials that are characterized by increased strength.

The machine stands out for its low sag characteristics when working on uneven ground. And at the same time, the excavator provides high quality work, as well as increased productivity. In terms of efficiency in earthmoving, the Liebherr 944 can be called one of the leading models.

It should be noted that the manufacturer developed the design of equipment specifically for operation with high loads. It is made of high-strength steel and ensures the most efficient use of the machine in a wide variety of applications. The high versatility of the excavator is due to the large number of additional attachments and several options for the platform used, which allows the owner to assemble from all this the most suitable variation of equipment for doing specific tasks.

It is also necessary to highlight the next element of the model. The excavator is equipped with a modern operator's cabin, which includes reliable safety systems (ROPS and FOPS), microclimate systems (air conditioning and heating system), as well as a high-quality radio receiver. The design of the cab is characterized by fairly large windows that provide a wide visibility of the working area. Inside, a comfortable seat is installed as standard with several adjustments and air suspension which excludes vibrations. For achievement advanced level The cabin has been supplemented with special reinforcements that guarantee reliable protection in the event of a rollover of the excavator. The modern FGPS device, which is included as standard in the cab, is also responsible for safety here. In addition to rear-view mirrors, a camera can be optionally installed to provide a clear image of the background. Thanks to it, improved visibility is achieved and possible dead zones of visibility are excluded.

The basic version of the Liebherr 944 is equipped with a Liebherr SW66 quick release mount which has hydraulic drive and a special mechanism that automatically lubricates the connections of the working equipment. As previously described, the technique can be equipped with many additional units that expand the scope. Among these, it is necessary to highlight hydraulic shears, a hydraulic jackhammer, clamshell buckets, a ripper, an auger drill, a grab and several types of buckets that differ in their capacity. All of the listed equipment is the most popular, but in fact this list contains many more attachments.

This model uses a diesel six-cylinder power unit developed by Liebherr. The engine has the D936L index and is equipped with direct injection, fluid system cooling and turbocharging system, which, paired with a special intercooler, provides quite excellent power performance. So, the unit is able to develop a rated output power of 190 kilowatts, which translates to 258 horsepower. The engine transmits power directly, because this excavator model is not equipped with a gearbox. All movement of equipment is carried out only at one speed, namely 5 kilometers per hour. The main feature of the unit is quite good efficiency, which, with a capacious fuel tank (705 liters), provides long-term operation without stopping to refuel.

Purpose

The main goal in the development of the Liebherr 944 crawler excavator was the ability to move large mass soil and various materials mined in mines and quarries. But the numerous features of the technique have made it possible to significantly expand the scope, since the model is currently used in almost all areas of activity, from construction to large industrial sectors. Everywhere the machine is used for loading and unloading any cargo, dismantling, transshipment operations, all types of earthmoving work and much more, depending on installed equipment. But it is worth noting that most of the work performed is carried out with the help of a standard bucket, which has an average capacity. It is traditionally used to transport equipment to work sites. special transport. And this is not due to the fact that the equipment moves rather slowly, but also because of the possible damage to the asphalt and concrete pavement of road sections that caterpillars can cause.

Modifications

This model served as the basis for two modified versions. Let's take a look at them in detail:

Modification Liebher 944B. This model is optimized power plant, which made it possible to achieve increased operational and technical parameters. Another significant difference is dimensions excavator in connection with the installation of an extended caterpillar base. AT standard equipment This model has an earthmoving bucket of increased or reduced volume.

Modification Liebherr 944C. Distinctive features such a modification is the presence of a modern hydraulic system with increased operating parameters. The hydraulics used can significantly reduce material investments during maintenance, as well as reduce fuel consumption. In terms of performance, the version also outperforms the standard excavator.
