Polygon Volvo Construction Equipment in Sweden
• Polygon Volvo Construction Equipment in Sweden
As a child, every summer I spent in the village standard. And he lived in the neighborhood Uncle Ivan - tractor driver who worked for the K-700. Sometimes he entertained kids and rolled us in the cabin. We were delighted. I remember well the stifling and dusty cabin, which needed good for something to hold on when the tractor is driving along a country road. It was still noisy. At the windshield he curled a swarm of flies.
If a few decades ago the main requirements of such a technique was their power, maneuverability and performance, it is not less focus on driver comfort, environmental friendliness and safety. As well as in the automotive industry, progress in the development of construction machinery is not in place.
I recently visited the demonstration polygon Volvo Construction in Sweden, where I manage a large mining truck, loaded it with an excavator and worked on loader. I did not know that to manage such huge monsters can also be comfortable as a passenger car ...
Today Volvo CE released over 220 different models of construction machinery. To meet market demands, dozens of new models developed and come out every year. For example, in 2012 the lineup has replenished with 60 new models.
Articulated Haulers from afar like a normal dump trucks. But this is a completely different technique in its design. It's like a clock with manual winding and a battery - like almost the same thing, but the filling is completely different.
So looked the world's first articulated hauler, which was issued in 1966. On it it is perfectly visible, so to speak, the genesis. This is essentially a tractor without front wheels, plus a body connected controlled articulation.
This is about a cab ride I was a child in the fields.
And so the cabin looks modern articulated truck Volvo CE.
These trucks are used as a dump alternatives to work in off-road conditions. They are used for earthworks and road construction, in coal and ore mines.
The idea is that if a mining company relies in its work than the traditional karerniki, and sochlenenniki, it
significantly saving on construction of technical roads - roads for articulated dump trucks can be uneven (at karernikov on these eventually destroyed the frame) and a twisted, narrow. At the close of mine workings sochlenenniki altogether indispensable.
Another plus side sochlenonnikov - safety. Even if the truck rolls over - due to improper loading, cross-country, or, as here, the bucket of the excavator, it is not completely inverted.
Flotation technology is impressive.
The usual dump truck - is a powerful frame, which is mounted on the engine, body, cabin, and so on. From design flow sochlenennikov obvious advantages. They ￼dolgovechnee (does not break the frame, which is not present), maneuverability and cross. 30-40-ton sochlenennik comparable in price with a similar frame quarrying. The big advantage is its mobility - movement from object to object much easier to have an articulated dump truck. For this reason sochlenenniki ousted ramniki in Europe in the segment of 30-40 tons.
Articulation looks. There extends driveshaft transmitting torque to the rear axle. Needless joint has all possible degrees of freedom and is driven to the left and right.
Turn steering changes the pressure in the hydraulic cylinders and truck folds. The wheels are always the same in their niches exactly.

By the way, the first dump trucks that have appeared suspension were just dump Volvo. This will not only keep back the drivers, but also significantly increase the rate of return of empty equipment. Also, the first seat belt was installed on Volvo cars.
One of the options of standard mining team looks like - a bulldozer, excavator and dump truck. Origin rock moves, the second loading it into the body, the third removal. Now the three are often replaced with a pair of front loader + articulated hauler.
For example, the wheel loader L220G playfully raises cobblestone weighing 10 tons.
Wheel Loader performs face trimming and loading of the rock mass in the dump.
is easy Despite its size, operate the loader. You can learn in a day, the main thing - to get used to the size.
Counterpart Sergei behind the wheel loader.
Loader is controlled by "turning point" frame, which is good for maneuverability.
Maximum capacity Volvo CE trucks - 15 tons for L350F (c bucket at work).
truck cab interior. There is everything for a comfortable operator environment - panoramic windows, comfortable seat and controls, air conditioning, radio, curtains on the windows.
I also was able to direct the excavator EC700C. Unaccustomed to all traffic go slower, but overall it appeared that operate such equipment quite difficult.
By the way, May 14, 2013 Volvo Construction Equipment celebrated the opening of the production plant of excavators in Russia - in the Kaluga region.
It turns out that when cornering is better to rely on the bucket and not to rotate with different rotational speed tracks - on loose ground excavator quickly buried.
When I pulled dashingly arms like a tank - one forward, two back - Instructor gritted teeth. In theory, so it is possible, but better not. For harmful caterpillars slip on huge cobbles, and so plainly will not turn, can only be dug into the rock.
Today in the world every year are sold 850,000 units of construction equipment. Russia accounts for 35,000, while the Chinese market is sold nearly 200,000 units.
Many thanks to Volvo CE companies for the organization of the trip and provided the opportunity to direct the heavy equipment!
