With 4,200 kW through the mountain. PREMIUM model of a "Gripper-TBM" tunnel boring machine incl. trailing arm, bottom segments and gear motor based on a prototype from HERRENKNECHT AG in Schwanau. Laterally extendable hydraulic cylinders clamp the tunnel boring machine to the tunnel wall with the grippers that give it its name. Hydraulic jacking cylinders steer the route with swiveling movements and impart contact pressure to the drill head. With a rotating cutting wheel, this breaks rock chips out of the rock, which are then transported away via scrapers, channels and a conveyor belt. Rock support during tunnel excavation is provided by various machine devices, for example for installing reinforcement mats and rock bolts, mounting stabilizing steel arches or taking test bores for preliminary exploration. On the trailer of the "Gripper TBM" are conveyors for the removal of the rock, additional drilling equipment for the installation of rock bolts, devices for the concrete lining of the tunnel tube and the installation of utilities, as well as various lines, transformers, pumps, equipment containers and control units. Last but not least, the trailer provides the construction materials required by the "Gripper-TBM". 42 invert segments for lining the tunnel floor and a geared motor, item 180722, for rotating the drill shield are included in the kit. Connection is made to max. 5 V DC. Supplementary set: follower for "Gripper-TBM", art. 130899 with further follower variants available separately.
