Atlas Copco attends Expomatec 2011 with its extends Dynapac and drilling solutions

The new range of extends Dynapac subdivided in two ranges: crawler and wheeled equipment. A total of nine all-new extends; six crawler with working width of 2 meters to 14 meters and three wheel with widths of 2 meters to 9 meters work. Machines have more advanced features of the market to ensure comfort of operation, with the maximum availability of the equipment and which, in turn, provides significant environmental benefits. The most noteworthy features are: a sliding platform in the SD series that gives visibility out of the ordinary, a leveling system integrated in the control of the team and a 'Safe impact system' security in the front roller systemto ensure the approach and docking of the truck into the hopper of the machine. In each series, F and SD, there is the option of having longer and wider hopper. In addition, increased the size of the conveyor and the thickness of the direction of the endless has decreased.

Subjected to various tests in the lead-zinc mine of Lovisa, in central Sweden, during a period of almost a year, and has passed all the tests with the best results, it has achieved a dramatic increase in productivity in cargo operationsas well as improvements in the working environment. Working for more than 2,000 hours, achieved an increase in the productivity of the almost 100%, going from two loads per shift, almost four. In addition, what before was achieved with four wheel loaders in operation now is achieved only with one.

The design of the Boomer XL3 D, aimed at users who prefer a traditional direct control system, has emerged about the safety, ergonomics and productivity. The team has a body with homologation FOPS who also can be equipped with a vertical lift of 1100 mm to have good visibility of the work area. Optional cabin offers a high degree of comfort for the operator, with a noise level in its interior that does not exceed the 80 dB (A). In addition, the air conditioning unit ensures an acceptable temperature level.

Terranox hammers are specially designed for applications of Geotechnics where secure and reliable drilling is of the utmost importance, even more than the speed of drilling. In many urban works, the use of high pressure for high performance teams are restricted due to the risk of damage to nearby structures. For this reason, they have been developed for optimal performance for low pressure operation. Combined with systems of drilling with pipe of lining, Symmetrix and Elemex Odec drilling Mustang cars and teams of injection Unigrout, provides a comprehensive solution for the applications of Geotechnics and foundations.

To overcome this challenge, Atlas Copco has developed the new system drilling with lining Elemex and scan control to meet the concern and care of the use of compressed air for the damage that could result in nearby structures due to loss of air or sobreperforació. The use of the hammer in work of Foundation facility provides multiple benefits; high productivity, straight boreholes and ability to penetrate great depths. However, when working near existing foundations method poses a great challenge: control the movement of the detritus in the grounding rod with compressed air.

Implementation of micropiles through the use of auto-perforantes MAI. Through the use of the lost mouth, the installation of the MAI stud is continuous without extraction to achieve the desired depth. For a 12-15 m micro is easy to connect standard bars of 3 m or 4 m are manufactured from steel according to EN 10083-1 tubes, the bar MAI is laminated in cold to form a profile of standard thread (R32-R51 and T76). Bolts can be installed in a variety of soils and terrain (such as sand, gravel, not consolidated land, rocky terrain, jetties, etc.) preferably in areas where drilling has to be jacketed. The anchor MAI is applicable on cohesive ground as not cohesive.

With the arrival of this new hammer on bottom, Atlas Copco offers the possibility of drilling of boreholes from 110 mm to 130 mm (45/6 "to 51/8") in diameter, with a great return, thanks to its low power consumption. In addition, the modern equipment of drilling of high pressure can take full advantage hammer that can withstand a nominal pressure of 35 bar. Also, this model this model is maintenance-free, so you have a useful life greater than a hammer 10-15% equivalenteo. In addition, customer, instead of buying a new hammer can recondition your Secoroc COP Gold up to three times using the COP Gold E-kit and restore original benefits at a fraction of the cost.

New developments of the mark are always aimed at getting hammers to improve peso-potencia to the previous model in terms of the relationship. For this reason, it's design hammers that weighed slightly less and have a capacity of upper knock the cost of operation through lower consumption to thus be able to reduce the cost of the investment (machine smaller carrier), and most importantly. Good examples of this are the latest models launched into the market during the past three years, both in the medium range and the heavy, such as the 750 MB, 1500 MB, 2000 HB, HB 2500, 3100 HB, HB 3600 and HB 4700. In addition, the Autocontrol function is responsible for maintaining the proportion proper energy and frequency of impact to achieve the greatest possible power, and DustProtector II (a combination of several scrapers) prevents the intrusion of abrasive dust particles and foreign bodies in the lower part of the hammerthus extending the life of the same.
