The M11 Gayrettepe-Istanbul New Airport Line starts from Gayrettepe station, through Kağıthane, Kemerburgaz, Göktürk, İhsaniye, Airport-2, Airport-1 Stations and reaches at Airport-3 Station. The project will be bored with 10 TBM’s. Two of which are delivered by our customer.
Transport to the segment feeder of the erector
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.
