Atlas Copco recently introduced its PROi gas breaker with electronic fuel injection (EFI), an industry first that offers significant benefits for users needing to break concrete, cut asphalt, tamp soil or drive ground rods. The Cobra PROi provides as much as 10 percent more power than its predecessor, the PROe, at all working speeds, while optimal combustion reduces fuel consumption by as much as 10 percent. Operators can start the breaker in almost any climate or at any altitude.
Atlas Copco launched the PROi breaker during World of Concrete in Las Vegas.
Unique EFI concept ensures smooth running
An integrated mechanical fuel pump employs a unique system that maintains constant pressure to the regulator without electricity. Atlas Copco also designed the PROi with a custom electronic fuel injection system that uses just 3 psi, 40 psi less than standard EFI systems. This approach minimizes pressure variations and voids in the fuel, ensuring smooth running. Starting the breaker is easy in any conditions; the Engine Control Unit activates during the first revolutions when the user pulls the starter cord.
Low vibration levels, easy to transport
Putting the operator first is embedded in Atlas Copco’s DNA, and the Cobra PROi is a good example. Hand-arm vibration level on 3 axes is below 4 m/s2 to minimize operator fatigue. The light, compact machine weighs just 53 pounds, so users can easily move it and transport it in a car’s trunk.
While the PROi may be easy to handle, the unit packs a punch. Its 2-stroke, 90cc engine delivers as much as 44 foot-pounds of breaking force due to the unique arrangement of the gearbox percussion system. This force is equivalent to 793 pounds hitting the chisel every second.
New kill switch
At first glance, the new Cobra PROi looks like other gas breakers in the Atlas Copco Cobra range, however, rather than the trigger with the kill switch on the left handle, Atlas Copco has moved it to the right handle on the PROi. In addition, the kill switch is a button rather than a lever, which enhances ergonomics. The button also automatically presses back out, eliminating the risk of remaining in the ‘off’ position, which would prevent the operator from starting the unit. Because the breaker also has fuel injection, there is no need to choke the breaker during startup. This ensures dependable startup performance in cold and hot climates.
Low maintenance requirements
Since the Cobra PROi stays in tune, maintenance is minimal. Also, its high-capacity air filter has a long lifetime and can be easily accessed for fast servicing.
