Atlas Copco Cobra Petrol Breakers

Multi-Purpose Breakers/Drills

When work is unpredictable and you are pressed for time, you need to trust your gear. The Cobra™ is a teammate that you can grab and go. Anywhere. A Cobra™ is ready to handle almost any task, in any location. Here is what we mean by “multi-purpose”.

MP-1

Tie Tamping
When trains follow their path, the ballast gets pushed out from underneath the sleepers. Tamping is the process of securing the ballast under the railway sleepers.

MP-2

Concrete Breaking
The harder the material, the more weight and impact force is needed. Non-reinforced concrete is medium-hard and reinforced concrete is considered hard. Re-inforced concrete takes higher impact force (weight) and fewer blows per minute.

MP-3

Asphalt Cutting
Asphalt is flexible and considered a medium hard material. That means you need less impact force and more speed compared to breaking concrete. Good sound and vibration protection help keep your renovation work profitable.

MP-4

Digging
When you dig with your Cobra™ you need to take soil type and compaction level into account. Tools include digging chisel for compact soils, digging spade for softer ground and clay spade for soils with high plasticity.

MP-5

Post Driving
Driving posts, spikes and rods often require much lifting and moving between work positions. The same often goes for driving rods and spikes along roads or railways. Working without hoses, compressors make work much easier.

MP-6

Compacting
Soil is Mother Nature’s upper crust. You tame it and make it stable by compacting. Different soils need different types of treatment – and tools.

MP-7

Drilling
You need speed, lower impact force, turning and flushing when drilling holes. High speed and lower impact prevents the rock from breaking. Flushing removes drill chips from the hole while you are working.

Cobra Breakers Range

 Cobra TTe Breaker (long)

 Tie tamper, long version
Cobra_TTe Breaker

The Cobra™ TTe is optimized for railway applications and especially designed for tie tamping. It works at the relatively high frequency of 1,620 blows/min. Its impact energy is high enough to push the ballast back under the ties and low enough to prevent pulverization of ballast. The petrol-driven breaker is ideal for tie tamping in more ways. You don’t have to worry about compressors, hoses or cables, which makes it easy and safe to move around in rail yards and other high-risk environments with constant heavy traffic.

Easy Starters
TTe breakers have decompression valves and electric ignition. It makes them easy to start in all weather conditions.

Easy Transportation
Weighing in at just 24 kg the Cobra™ is easy to carry around and to fit in a car trunk.

Railway Specialist
The Cobra™ TTe delivers just the right amount of power for tie tamping.

We Take Care
The HAPS system (Hand Arm Protection System) makes the Cobra™ unique. It lets you do heavy duty work more than two times longer compared to other petrol driven breaker models.

Two Sizes
When working in hazardous areas, like a switchyard, two different sizes to choose from will come in handy.

Air Filter
Your machine has a natural oil consumption . We have made it easy for you to check and make sure oil levels are optimal.
