Interview with Emil Nathanson, Innovation Manager at Herrenknecht AG
Mr. Nathanson, can you give us more details about the development process? How did you get to this idea and to its implementation?
Emil Nathanson: Actually, the CoT principle is nothing new and is being used e.g. to visualize the torque acting on a TBM’s main drive. Utilizing the CoT in the context of directional steering began with the Herrenknecht’s development of the continuous advance for soft ground TBM. When tunnelling continuously in soft ground, ring-building and advance take place simultaneously. Some thrust cylinders...
Visualizing the Center of Thrust
The main feature of the CoT steering system is the visualization of the center of thrust, which represents the point of application of the total thrust force...
