MTB 155 TN

> Tunnel Breakers

We designed a special piston for tunnel operations for MTB “5” serie breaker models. The most important reason for their demand in tunnel operations is their superior impact power, continuous impact ability in scanning operations and their ability to work in steep angles. The lifetime of the piston is prolonged by %60 thanks to  their automatic greasing system and special seal design. They block the dust and debris from entering the system with their special greasing system and their wiper seal in the lower bushing for tunnel operations. This way, tunnel breaker series has earned a place between the top selling breakers. To be used in the Tunnel Series we produce 6 different models with 2 chassis designs between 900-1575kg  for the excavators in the range of 10-26 tonnes.

MTB 155 TN breakers which are produced to be used in the tunnel breaker series are produced as 1575 kg. for the excavators in the range of 18-26 tonnes.
