Abstract
A trench excavator has a raisable and lowerable boom swingable about a vertical axis on the self-propelled chassis which is mounted on tracks. The boom carries a cutting head which is swingable about a horizontal axis at the free end of the boom so that the excavator tool can be inclined downwardly toward the chassis. According to the invention, the inclination of the cutting head is measured and the measurement is used to control the drive for the track.
