Redesigned Atlas Copco Cobras PROe and TTe pack more punch

Atlas Copco has redesigned its range of Cobra PROe and TTe petrol breakers to deliver more power and less vibration. According to Atlas Copco, the percussion mechanism delivers engine power with minimum losses to the tool tip, resulting in impact energy of 60Joules for the PRO version and 40Joules for the TT version. The PROe is ideal for breaking, asphalt cutting and post driving. With 60Joules at the tool tip it can break silica rich rocks and reinforced concrete, according to Atlas Copco. The Cobra TTe i

Fewer vibrations from Cobra PROe and TTe petrol breakers
Atlas Copco has redesigned its range of Cobra PROe and TTe petrol breakers to deliver more power and less vibration.

According to 161 Atlas Copco, the percussion mechanism delivers engine power with minimum losses to the tool tip, resulting in impact energy of 60Joules for the PRO version and 40Joules for the TT version.

The PROe is ideal for breaking, asphalt cutting and post driving. With 60Joules at the tool tip it can break silica rich rocks and reinforced concrete, according to Atlas Copco.

The Cobra TTe is the most optimal punch for tie tamping. The unit’s 40Joules at the tool tip delivers high enough energy to push the ballast back under the ties and low enough to prevent the pulverisation of ballast.

Both versions are available with 25 x 108mm shanks, making them shorter and lighter which also diminishes vibrations. To dampen the tools further, both have improved hand-arm protection systems.They also run on alkylate petrol to reduce an operator’s exposure to harmful exhausts and also lower the environmental footprint.

    There are various ways of building a tunnel, and for excavation jobs many contractors prefer to use versions of standard machines that have instead been converted to suit the confines of tunnelling applications. Some contractors opt to adapt their own units and with ventilation being an issue in underground work, engine emissions are a key focus when adapting machines. Exhaust filters and other after treatment solutions are usually required and there are an array of off-the-shelf packages available as well

    Atlas Copco says that its LP705 walk-behind duplex roller shares features with the recently introduced LP605 model. The LP7505 is a larger model and retains the flip-up hood seen on the LP605, which allows easy access for engine maintenance or battery charging. Of note is that the manual brakes have been replaced with new automatic hydraulic brakes; when pressure goes down, the unit brakes automatically. If pressure goes up, the brakes are released. Other features include new scrapers to avoid material adhe

    Atlas Copco is introducing mobile electric Variable Speed Drive (VSD) air compressors to its E-Air range. These electric compressors are said to suit working in a low emission zone. The absence of diesel emissions, combined with the low noise levels (as low as 61dB(A)), suits the E-Air range for underground applications like tunnelling, as air ventilation is a part of their running costs. While the fixed-speed electric compressor needs a start-up current peak, the VSD electric range offers versatility. Ef
