Tunnel Engineering
Electrohydraulic Monorail Overhead Conveyor
The NEUHÄUSER monorail suspension system optimizes the transport of materials and excavated material in tunnel construction. This system enables rapid transport even with heavy loads and helps make tunnel construction more efficient. A particular advantage is the ability to pour concrete on the tunnel floor while tunneling is still in progress, which saves both time and money.
The electrohydraulic monorail hoist system has already been successfully deployed:
+ Gotthard Base Tunnel North
+ ICE Tunnel (open-cut construction)
+ Garching Metro
+ Nuremberg Metro

Example: Nuremberg Subway
The electrohydraulic monorail suspension system from NEUHÄUSER is being successfully used in the construction of the Nuremberg subway. It is ideal for transporting excavated material and concrete using a floor-discharge mechanism, as well as for transporting general cargo.

Advantages of a monorail suspended conveyor system over conventional tunnel boring
| No exhaust emissions, as the monorail suspended conveyor system is electrically powered |
| Unlike the use of dump trucks, the monorail suspended conveyor system does not place additional stress on the tunnel floor |
| Buffering of excavated material behind the tunnel boring machine through the use of multiple transport containers |
| Particularly suitable for small tunnel cross-sections where a conveyor belt system cannot be installed |
| Effective time savings: The tunnel floor is concreted simultaneously during tunneling |

Tunnel Fire Suppression Systems from NEUHÄUSER
Tunnel Fire Suppression System—Faster Than the Fire Department!
The tunnel fire suppression system from NEUHÄUSER combines advanced overhead rail technology with IFEX impulse suppression technology. The NEUHÄUSER-IFEX fire suppression vehicle moves along a rail on the tunnel ceiling and can drastically reduce temperature and smoke development in a very short time. This minimizes damage inside the tunnel and significantly improves safety.
A fire in a tunnel can spread extremely quickly and have devastating consequences if it is not brought under control immediately. The tunnel fire suppression system ensures rapid and efficient firefighting to minimize this risk.

Rapid fire detection and quick containment of fire, smoke, and temperature are critical for survival in tunnels. The NEUHÄUSER tunnel fire suppression system offers an advanced solution here.
With conventional methods, it is often impossible to reach the source of the fire in the tunnel immediately. The combination of NEUHÄUSER and IFEX provides a compelling solution:
+ Ultra-low-profile tunnel firefighting vehicle: The NEUHÄUSER tunnel firefighting vehicle travels along the rails on the tunnel ceiling to the source of the fire, easily passing over vehicles and obstacles.
+ IFEX impulse extinguishing system: This system propels extinguishing agent directly into the source of the fire at high speed and with high kinetic energy.
These technologies extinguish the fire in the shortest possible time and immediately and significantly lower the temperature in the tunnel. This minimizes damage and significantly improves the safety of people in the tunnel.
