Atlas Copco’s new cleaner Cobras
The 2010 generation of Atlas Copco Cobra™ petrol drill and breakers meet the stricter requirements of exhaust emission set by the US based Environmental Protection Agency.
Phase 2 of the Exhaust emission standards for small non-road engines of the EPA and its EU equivalent, EG 97/68/EG with amendment 2002/88/EG constitute a reduction of hydrocarbon and nitrogen oxide emissions and are probably the most demanding in the history of environmental regulations. Compared to the previous generation of Cobra™ machines, the emission of hydrocarbons has been reduced by approximately 50%.
Featuring improved carburettor and filter systems and redesigned and fine tuned noise reduction system, including a catalytic element, the new generation of Cobra™ petrol drill and breakers meets the requirement for exhaust emissions demanded by the stricter emission limits. The new Cobra™ petrol breakers are easy to start. All models feature an electronic ignition, choke and a re-designed tank cap. Cobra™ Pro and TT additionally contain a decompression valve. An optional guide roller is available for Cobra™ Combi to make it easy to pull downwards to start the machine when it is positioned high in relation to the operator. Long life and easy service is achieved through a high capacity air filter, which is easy to access for fast servicing.
All Cobra™ machines work independently from external power sources. Transfer to and off site is easy and can be carried out by a single operator. Cobra ™ Combi is a multi-purpose machine featuring high impact mechanism with rotation option and a built in compressor, ideal for onsite jobs such as breaking, drilling, cutting, driving and compacting. Cobra™ Pro is the combination of high percussive energy and high blow frequency. It delivers almost twice the impact energy of other petrol-driven breakers and offers the same power-to-weight ratio as many pneumatic or hydraulic breakers. Cobra™ Pro is used for breaking concrete and asphalt, digging, driving posts and fences, rods and spikes and for tamping and compacting. Cobra™ TT has been specially designed for tie tamping. It works at the relatively high frequency of 1,620 blows/min and the impact energy has been optimized to prevent pulverization of ballast
