Most models of Hyundai excavators are equipped with connectors through which attachments are connected, which significantly expands the scope of their application.

The main advantages of Hyundai crawler excavators

A crawler excavator is a type of earth moving machine designed to work in off-road conditions. Crawler models have about 100 modifications, distinguished by load capacity, dimensions and digging depth.

The performance of machines depends 90% on the quality of the engine. This can be achieved by power units from the American company Cummins and the Japanese corporation Mitsubishi. At the same time, Hyundai excavators supplied to the Russian market are in the vast majority of cases equipped with American engines. This factor is explained by the lower cost of their diagnosis and repair.

Thanks to their design features, Hyundai tracked vehicles have a number of advantages:

• exert low pressure on the ground;
• have increased maneuverability and load capacity;
• allow the use of excavators in intensive operation mode (subject to timely diagnosis);
• have increased maneuverability thanks to the rotating platform.

If we compare the tracked models of Hyundai excavators with similar models from other manufacturers, we can highlight a number of advantages. Among them is a wide selection of modifications weighing from 11 to 50 tons, which allows you to select equipment to perform any type of work, even in limited space.

The increased width of the tracks that Hyundai excavators are equipped with guarantees stability of the equipment, regardless of tonnage, even on the steepest slopes.

The main advantages of Hyundai wheeled excavators

In Russia, Hyundai wheeled excavators are well-deservedly popular, as they are able to work in almost any conditions. They are used for loading/unloading bulk and lump materials, soil development and quarry work.

The enlarged cab provides excellent all-round visibility, allowing the operator to complete tasks quickly and efficiently. A feature of Hyundai wheeled vehicles is maneuverability. They are able to independently reach an object in urban environments, covering long distances.

Wheeled Hyundai models are equipped with American and Japanese engines from Cummins and Mitsubishi. The weight of the vehicles varies from 4.5 to 20.6 tons. The bucket volume ranges from 0.07 to 1.3 m³, and the maximum digging depth is 4.8–6.3 meters. Additional convenience is provided by a computer control and monitoring system for units.

All wheeled excavators manufactured by Hyundai can be equipped with additional attachments, such as a hole drill, hydraulic hammer, leveling bucket or trencher. Thanks to them, machines can turn into multifunctional devices capable of performing a wide variety of jobs.

Purpose

Initially, this machine was developed to perform construction tasks, but due to its many advantages, especially its versatility, many other different areas have become interested in the Hyundai R250LC-7 excavator. Currently, the technique is very popular in large-scale construction of any objects; large industrial sectors; rural and communal services; quarries; deposits; oil producing corporations; mining industries; and road repair services.

In all this, the excavator is able to cope with a large number of different jobs, namely: digging pits, trenches and ditches, as well as filling them up; loosening frozen soils and rocks; leveling working areas; planning the area for construction; development of wells and quarries; excavation; drilling wells, as well as holes of various diameters and depths, which can later be used for the construction of fences and pillars; cleaning the bottom of rivers and small reservoirs; loading bulk and lump materials into the body of a dump truck; moving various bulk materials over short distances; destruction of various brick, concrete and reinforced concrete structures; opening of asphalt and concrete pavements and a host of other tasks.

Due to the low speed of independent movement, transporting an excavator over long distances will require the use of a specialized trailer and tractor, which is, in principle, characteristic of almost every modern special equipment.
