Company Soil

With pyatikubovym loading bucket can be downloaded once the truck. Base 3760 and 2440 mm gauge make this giant is very stable even in the corners. The customer could choose the right tires at the factory or custom finishing the map. Was possible even a delivery truck with a wheel snow chains, because in such a capacity and operating conditions of slip inevitable. Therefore, the whole machine is surrounded by a protective lifelines.

Produced FIAT-ALLIS and wheeled excavators, because this kind of construction equipment does not replace. Caterpillar has plenty of information regarding this issue. Model FE 18R equip diesel engine 134 hp and bucket 0.72 m3, which raises the load mass of 15 800 kg to a height of 8234 mm depth 5894 mm. As can be seen in the picture on both axles installed dual wheels. At customer excavator could be all-wheel drive or with a single leading axle. The customer chooses and the length of the boom, which was three dimensions. As optional equipment offered a choice of tires, up to the single generalist.

Design of the excavator engaged the Italians, and I must say that for those years, he has turned out very cute. The company also develops and produces scrapers, single-and twin-engine. Model 262-B was built on a twin-engine scheme (tractor and a bucket) with a total capacity of 520 hp Despite the old-fashioned look, this is quite powerful scraper due to its specific indices enjoyed great popularity. Working volume of the bucket (heaped) was 16.1 m3 load capacity – 22 860 kg. Bucket penetrated into the soil to a depth of 330 mm and load just a few minutes, everything depended on the hardness of the soil and the construction of replacement blades. Finally, a word about the wheeled graders, who appeared on the market along with the rest of the equipment FIAT-ALLIS. As an example, we chose a model 65 – the most easy grader in the program group. His own gross weight was 5,116 kg, while the mass of the captured ground (without slipping) – 2763 kg. The minimum rate – 3,6 km / h. On this model, the grader was no cabin, however, for work on small construction sites and small amounts of soil grader was irreplaceable.

Myth: Bus Rear

Thus, in the correct installation at the rear subwoofer bass is still the front. The trick is that the human ear perceives the direction of the sounds only in a certain frequency band, and this band is for outside the range of the subwoofer. The figures are as follows: in theory, affect the localization of components of the sound with frequencies from 300 Hz to 3000 Hz, while the subwoofers are rarely cut-off frequency low pass filter (LPF) above 100 Hz. In other words, the source of the bass will seem to us to front speakers. It would seem that such an alignment is completely solves the problem, and everything should be fine, but the practice is different.

In fact, a tempting picture 'Rear subwoofer – bass front' will arise only if the installation was engaged in a skilled master, and the systems in which the bass is still behind – not so rare. Even in competitions avtozvukovomu sport where preparation machines do not dilettantes, rear bass is a perennial headache for the participants. There are several reasons: firstly, if the LPF not efficient enough, the subwoofer can reproduce such components of sound, which can affect the localization and, secondly, if the bass power the front speakers are small, then between the subwoofer and the front will be 'a failure', and thirdly, when there is insufficient sound insulation, together with sound of the subwoofer, we will hear from behind a lot of extraneous overtones produced by rattling panels and obshivki.Est and a few other nuances, which we do not sharpen vnimanie.Chto do? Here are some tips can follow to avoid the localization of the bass back and 'make friends' theory and practice: When choosing an amplifier for the subwoofer takes precedence model, in which the built-in crossover (namely – LPF) has a higher slope decay – 24 or even 18 dB / oct.
