Editorial Interempresas21/05/2013

The hydraulics hammer HB 4100 of Atlas Copco carries from August realising a work of demolición underwater near of the island of Giglio, in the Italian region of the Toscana. The work engloba in the first phase of an important operation of maritime engineering in which Atlas Copco collaborates closely with Salts SpA, a known company of skilled Italian construction in projects of infrastructures and maritime.

For the works of demolición underwater of rocks of granite to a depth of 10 metres, Salts SpA employs a hammer HB 4100 of Atlas Copco, with a weight of 4.150 kg, connected to an excavator of orugas Liebherr 984 mounted in a pontón floating. The operario of the excavator works of form 'blind' from the cabin of the excavator, by what depends exclusively of a system of follow-up GPS and the instructions of the submarinistas.

Hammer HB 4100.

The execution of an alone impact with the camera of the career of the pistón flooded would cause damages in the hammer. Thus, so that the HB 4100 work subacuáticamente of effective way, realises his work with a compressesor XAHS186 of Atlas Copco. The compressesor prevents that between water in the machine injecting air compressesed. The channels for the air compressesed are integrated of standard form in the hydraulics hammers of Atlas Copco, what allows to use them in underwater works. A system of hygiene detains immediately the career of the hammer if, by any reason, the compressesor detains the injection of air compressesed.
