The pneumatic wheeled excavator Hyundai R170W-7 is a representative of a series of earth-moving machines produced by the Korean manufacturer. This model appeared on sale on the Russian markets for various special equipment not so long ago, but in a fairly short time it gained great popularity. This is because the machine combines more power; ease of maintenance; simple control of both movement and working parts; modern mechanical engineering technologies.
The manufacturer included all the basic data about the excavator in the model index. Let's take a closer look at what R170W-7 means: The type of machine is indicated by a capital letter, in this case it is R - excavator equipment.
The numbers following the vehicle type indicate an operating weight of 100 kilograms. But it is worth noting that in some models this number is rounded.
The last letter in the excavator index indicates the type of chassis used. W – pneumatic wheel.
Well, the last number, like many other excavators, indicates the series.
The excavator is equipped with one of two diesel engines: Mitsubishi S6S-DT or Cummins. The rated power of the first reaches 86.8 kilowatts or 118 horsepower, while the power of the second unit is 92.7 kilowatts or 126 horsepower. Both engines are famous for their high reliability and long service life.
Purpose
The main purpose of this excavator is to carry out earthmoving work. The scope of application of the machine is quite wide. It is capable of performing such types of work as quarrying, digging trenches and pits and filling them, creating soil embankments in certain places, loading and unloading materials of various structures.
Hyundai R170W-7 has good technical characteristics, which also allows it to take part in working with hard ground (rocks, hardened clay, frozen soil). This model is capable of handling soils of the first, second, third and fourth density categories without preliminary loosening.
Control system
The Hyundai R170W-7 is controlled using an innovative system that interacts with a hydraulic pump. The main element is the joystick, which guarantees high accuracy of operations.
Thanks to the keys, the hydraulic power increase mode is activated, as well as the speed reset. The dashboard displays information about the main operating indicators of the machine. The operator can control fuel consumption, power and engine speed. For maximum efficiency, several operating modes are provided:
- difficult;
- standard;
- hydraulic.

Attachments
As described earlier, the Hyundai P170B is a widely used vehicle, and accordingly, it has an impressive set of attachments. The manufacturer provided for the installation of the following additional equipment:
- Digging buckets. There are quite a few versions of buckets, distinguished by width, volume and type of task performed. This number also includes leveling buckets and trench buckets. All implements are mounted to the excavator handle without using a special mounting adapter.
Hydraulic hammers
This equipment is used both in construction and dismantling work, namely in the destruction of concrete structures and for removing the asphalt layer of road sections. There are a total of four versions suitable for this excavator model:
- Hydraulic hammer version Delta F15. The mass of such a weapon is 1400 kilograms. The minimum blow frequency reaches 450 beats per minute. The maximum beat frequency is 900 beats per minute. Each hammer blow delivers 4,234 joules of energy, making it easy to cut through virtually any hard material.
- Hydraulic hammer version Delta F15S. This unit is a kind of improvement of the previous equipment, namely, a special noise-proof housing was installed, which allows to slightly reduce the noise level arising during the working process. The minimum blow frequency reaches 400 beats per minute. The maximum beat frequency is 900 beats per minute. Each hammer blow delivers an energy of 4234 joules.
- Hydraulic hammer version Hammer HB 140. The weight of this version of the equipment is 1100 kilograms. The minimum blow frequency reaches 500 beats per minute. The maximum beat frequency is 940 beats per minute. The energy of each blow delivered by this unit is equal to 5132 joules. The Hammer HB 140 hammer can also be used in the construction industry, as it has several special tools: peaks, wedges and rammers.
- Hydraulic hammer version Impulse 300 ECO. Unlike previous units, this one has a small mass of 705 kilograms. But in addition to the smaller mass, its operational characteristics were also reduced: the minimum impact frequency reaches 450 beats per minute; The maximum beat frequency is 800 beats per minute. The energy of each blow is only 2441 joules. But still, this equipment can boast of its effectiveness.
- Hydraulic hammer version Impulse 300S. In terms of operational characteristics, this model is completely similar to the previous one: the minimum blow frequency is 450 beats per minute; The maximum beat frequency is 800 beats per minute. The energy of each blow is also equal to 2441 joules. But this one added a noise-proof housing, which increased the structural weight to 830 kilograms.

- Modification of Hyundai R170WD. The D index in this version indicates that the machine was originally intended to perform various dismantling jobs. The boom and handle are enlarged here, and between them there is an insert 2600 millimeters long. This allows the machine to reach fairly tall objects.
- Modification of Hyundai R170WLR. This version is a modified basic version, and here, as in the previous one, the boom and handle were enlarged, as a result of which it was possible to increase the height of unloading materials and the depth of soil digging.
- Modification of Hyundai R170WHS. The model with the HS index has a special rotating platform located significantly higher than that of previous versions. Allowed the machine to be used for work in water (cleaning the bottom of reservoirs, rivers and much more).
Peculiarities
The Hyundai R170W-7 excavator has several distinctive features:
The cabin of the car is quite spacious. The operator's workplace offers a wide view thanks to the large glass area, both in the front window and in all the others. The cabin is also characterized by minimal noise levels, excellent operator working conditions and increased comfort, which was achieved through the use of various heat-absorbing and noise-reducing materials. The levers, as well as the operator's seat, can be fully adjusted. The console panels can be easily removed or brought in for easier access. Also installed in the cab were a toolbox, a large windshield wiper blade, an ashtray and a lockable door.
The working parts of the excavator are controlled using a special joystick installed directly under the operator’s hand.
For convenience during further maintenance, the manufacturer has equipped the car with a fairly large hood, which, when opened, provides full access to almost all engine elements. Also, the entire structure can boast of a long service life and the availability of spare parts, both when searching and in terms of cost.
The handle has a special mechanism that allows for quick replacement of equipment.
The basic package is rich in terms of equipment, as it has a defroster, electric pump, radio, powerful heater, air conditioning, cold start system (useful when operating in hot climates), additional engine heating (designed for easy engine starting at low temperatures ) and an electric sound signal. All of the above ensures comfortable work regardless of various natural production factors.
Engine
The Hyundai P170B wheeled excavator is equipped with a Mitsubishi S6S-DT six-cylinder diesel power plant. All cylinders of this engine are arranged vertically in a row and have a diameter of 94 millimeters. The piston stroke is 120 millimeters. The total volume of all cylinders is 4996 cubic milliliters. The rated output power is 86.8 kilowatts or 118 horsepower. The estimated crankshaft rotation speed is 2100 rpm. In one working hour, this unit consumes about 85 grams of fuel per horsepower, which is a very good indicator in terms of efficiency. Liquid cooling system. Direct type electronic fuel injection system.
More recent cars are equipped with a different engine, namely a six-cylinder Cummins diesel unit. Its rated output power is 92.7 kilowatts or 126 horsepower. The cooling and fuel supply systems to the combustion chambers are the same as those of the previous engine.
