Laser Guidance System
AssemblyA motorized total station on the tunnel wall behind the machine measures a target unit on the machine, and the guidance computer compares the result with the tunnel's design line and shows the operator the deviation and the steering correction. Surveyors move the station forward as the tunnel advances. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
