We offer as part of our stock a younger AVN1200TB machine. The system did less than 1 KM of work and has been idle for a few years before we bought it. The machine is equipped with a strong peripheral drive of 4 hydraulic motors and has a 132 KW hydraulic power pack. The system can be offered as a complete working package. Currently available are all necessary components to make about 500 m tunnel length. There is a mixed grond wheel or rock wheel availble for the base diameter machine plus as option in addition also an extenion kit to DN1400 with standard wheel and an extenion kit DN1500 with a mixed soil cutting wheel. 

There is also a compact jacking frame of 520 Ton avaible for the system.

We also do have the necessary pumps and guidance systems.

We do have a number of slurry separation plants in stock as well

The equipment would be supplied in serviced condition with warranty. The equipment can be inspected in Germany.
