Tunneling technology

Electrohydraulic monorail conveyor

Material and overburden transport in tunnel engineering with NEUHÄUSER’s monorail conveyor system guarantees fast transport even with larger quantities. Furthermore, the option of concreting the tunnel floor even during tunnel driving saves time and money.

Our electrohydraulic monorail conveyor has been used in the following locations:

the North Gotthard Basic Tunnel
the open ICE tunnel construction
Garching Underground in Garching, Germany

One example: the Nuremberg Underground

Our electrohydraulic monorail conveyor is devised for transporting overburden and concrete by means of a bottom discharge wagon as well as for transporting unit loads.

The benefits of monorail conveyor over conventional tunnel driving

No exhaust emission since the monorail conveyor is operated electrically

The horizontal zone is no longer burdened by using the monorail conveyor in contrast to operating dumpers

Buffering the advance behind the part-face heading machine by using several transport containers

Especially suited to small tunnel cross-sections where it is not possible to install a belt conveyor

Effectively saves you time: it simultaneously concretes the bench during tunnel driving
