COBRA TT PETROL DRIVEN TIE TAMPER

Petrol Driven TieTamper/Breaker for Railroad Applications.

This machine is specially developed for tie tamping. An impact energy of 40 Joule combined with a frequency of 1620 blows/min means improved efficiency and drastically reduced ballast pulverisation.

In addition the Cobra TT is ideal for a number of railroad applications:

• Spiking wooden sleepers
• Digging cable trenches
• Concrete breaking
• Asphalt cutting and compacting
• Driving posts and fencing

Full Flexibility
The Cobra TT weighs only 24 kgs, and since it needs no hoses, cables or power packs, it is easily moved on and off track.

Unique Vibration Dampening
The Cobra TT is equipped with a new dampening system that virtually eliminates vibrations, and easily meets the most stringent standards in the world.

Environmentally Friendly
The Cobra TT engine meets the toughest emission limits. The low emission and vibration levels make the Cobra TT the most ergonomical tie tamper/breaker on the market.
