Hyundai R170 W-7 excavator – description and features

Hyundai R170W-7 excavator. Specifications, price and variation

Excavator Hyundai R170W-7 Pneumo-Long is a representative of the series of earthmoving machines, which were released by the Korean manufacturer. This model was not so long ago offered for sale in the Russian markets of various special equipment, but in a fairly short time has gained great popularity. This is due to the fact that the machine combines excellent performance, ease of maintenance, ease of operation of both the movement and the working body, and modern machinery technology.

The manufacturer has conveyed all the basic data of the excavator in the model. If we take a closer look at what the R170W-7 means: The machine type is indicated by a capital letter, in this case it is R-excavator.

Behind the machine type are numbers that stand for an operating weight of 100 kilograms. However, it is worth noting that in some models this number is rounded off.

The last letter in the excavator index indicates the chassis used. W means pneumatic wheels.

Well, the last number indicates how many more excavators, series.

The excavator is equipped with one of the two diesel engines: Mitsubishi S6S-D or Cummins. Rated power of the first one reaches 86.8 kW or 118 hp, while the capacity of the second unit is 92.7 kW or 126 hp. Both engines are known for their high reliability and long service life.

Planned application

The main purpose of this excavator is to perform excavation work. The field of application of the machine is quite wide. It is capable of performing such works as developing quarries, trenches and pits and backfilling them, making decking in certain places, loading and unloading materials of different structures.

Hyundai R170W-7 has good technical properties with which you can also work with hard soil (stones, hardened tone, frozen ground). This model can cope with floors of the first, second, third and fourth category of density without preliminary loosening.

Non-mounted equipment

As already described above, the Hyundai P170V is a wide-cut machine and has an impressive number of attachments. The manufacturer has provided for the installation of the following attachments:

  • Land Cover. There are several bucket options that vary in width, volume and task type. This also includes a leveling tool and a trenching tool. All tools are mounted on the excavator arm without the use of a special mounting adapter.

Hydraulic Hammer

This equipment is used in both construction and demolition work, namely in the demolition of concrete structures and for removing asphalt layer from road sections. There are four versions suitable for this excavator model:

  1. Delta F15 version with a hydraulic hammer. The weight of this tool is 1400 kilograms. The minimum rate of fire reaches 450 blows per minute. The maximum rate of impact is 900 strokes per minute. The hammer uses 4,234 joules of energy for each blow, which makes it easy to deal with almost any hard material.
  2. The hydraulic hammer is a version of the Delta F15s. This unit is a kind of improvement of previous devices, namely with a special anti-noise housing, which allows to slightly reduce the noise level arising in the course of work. The minimum frequency of blows reaches 400 blows per minute. The maximum frequency of blows is 900 blows per minute. In this case, each blow of the hammer receives energy of 4234 joules.
  3. The hydraulic hammer version of the Hammer HB 140. The weight of this version of the device has a value of 1100 kilograms. The minimum frequency of blows reaches 500 blows per minute. The maximum frequency of blows is 940 blows per minute. The energy of each blow of this device is 5132 joules. The HB 140 can also be used on a construction site because it has several special tools such as spades, wedges and ropes.
  4. Impuls 300 Eco version hydraulic hammer. Unlike the previous units, this one has a low weight of 705 kilograms. In addition to the lower weight, the performance has been reduced: the minimum impact frequency is 450 strokes per minute; the maximum frequency is 800 strokes per minute. The energy of each blow is only 2441 joules. In spite of this, this equipment boasts its efficiency.
  5. Impuls 300S version hydraulic hammer. This model is fully identical in performance characteristics to the previous model: the minimum impact frequency is 450 blows per minute; the maximum impact frequency is 800 blows per minute. The energy of each blow is also 2441 joules. However, a noise shield housing was added to it, after which the weight of the structure increased to 830 kilograms.
