At a vertical shaft worksite (e.g. water supply construction), overhead cranes are used to carry heavy loads down to the work floor at the bottom of the shaft. HOLOLIGHT DOT-CROSS, as in the picture below, projects a highly visible point-to-cross lighting pattern on the floor to give a visual warning to workers.
