IN ACTION ROUND THE WORLD Herrenknecht Gripper technology can be found in action in projects all around the world for all types of tunnel u and all diameters.
RING ERECTOR installs steel arches to
stabilize the excavated tunnel.
BUCKETS transport the excavated看淡一切无所谓的句子
rock behind the cutterhead onto a belt conveyor system.
CUTTERHEAD The excavation tools are mounted in the cutterhead, which also supports the tunnel face.GOTTHARD BASE TUNNEL
– Installed power: 3,500 kW – Weight: around 220 t
SHIELD (partial shield) supports the rock behind the cutterhead.
MESH INSTALLER places steel mats in the
inrted bolts.
DISC CUTTERS are mounted in the cutterhead and roll in concentric circles over the tunnel face. The rock is crushed by the contact pressure.GOTTHARD BASE TUNNEL怎么删除小程序
– Weight per disc cutter: around 125 kg – Contact pressure per disc cutter: up to 26 t
ROOF BOLTING UNIT can be moved around the machine’s axis. Drills holes for the bolts which stabilize the rock.
BELT CONVEYOR transports the excavated
material to the end of the back-up system.
WALKING DEVICE The rear of the TBM and the back-up systems rest on the feet of the walking device. They are lifted as tunnelling progress, and the back-up system follows.
GOTTHARD BASE TUNNEL
- Overall volume of excavated material: around 10.5 million m³.

shoes and press the rotating cutterhead against the tunnel face.
GOTTHARD BASE TUNNEL
– Thrust force: 27,488 kN total – Stroke: max. 2 m
SHOTCRETE ROBOT lines the tunnel with
shotcrete to stabilize it.
CONTROL CABIN From here the TBM driver operates the machine and monitors tunnelling.
