ABSTRACT:
A marking system indicates the location of lanes which are to be defined on a running track that has a given width and selected degree of curvature. A pivot is established at a fixed distance from the lanes to be marked. A boom assembly disposed laterally across the track carries a plurality of lane-marking devices individually spaced therealong. That assembly is supported for movement along the track. One end of the boom is propelled by a propulsion unit, and an alignment unit is coupled to the other end of the boom for enabling alignment movement relative to the pivot. A cable leads from the outer end of the boom over the inner end thereof and to the pivot for enabling alignment. Numerous detailed features contribute to an attainment of accuracy measured in fractions of an inch.
