Abstract

A method of controlling the direction of the work path of a machine, particularly a tunnel construction machine, characterized by the steps of: a) placing in advance a beam projector for the emission of its light beam on a parallel axis with the direction of the prescribed travel of the machine, b) initially adjust the position of the machine to center a pair of axially spaced targets apart on the machine in coaxial alignment with the light beam, c) maintain surveillance of the comparative images of the light beam in the two blanks during machine operation to see if there are indications of off-center machine movements, and d) readjust the position of the machine as necessary to restore the position of the machine in accordance with the direction of its prescribed work path.
