These are specific, solution-oriented barrier types.

The complete lifting solution we designed for inside a tunnel boring machine (TBM) consists of two vacuum lifters. The first vacuum lifter transports the tunnel segments and keystones to the segment feeder of the erector. To meet the erector’s position the suction pad is able to rotate 90 degrees during the transport. Vacuum lifter as part of the erector The second vacuum lifter operates as part of the erector and perfectly matches the interface of the TBM. To meet every required position the lifter is able to turn 360 degrees.

Over the last two decades IGNIS has been used in many tunnels, primarily to provide passive fire resistance to the concrete structure, whether this is a segmental tunnel lining, sprayed or cast in-situ concrete.

Advantages of the structure marker signs: 1) Impact-resistant, UV resistant and weather-resistant material (ASA) 2) Coloured-through letter and numeral inserts for long-lasting identification marking 3) Patented self-fixing system ensures that numerals and letters remain resistant to shocks and impacts 4) Mounting without screws, thanks to the secure snap-in closures
