Control, Guidance and Monitoring
AssemblyThe operator runs the machine from a cabin through a PLC that controls the drives, cylinders and conveyors and records every boring parameter. A laser guidance system shows the machine's position against the design line, and gas detection, cameras and fire suppression protect the crew. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
