Abstract (en)

[origin: WO8302165A1] A position indicating system suitable for use at container terminals for indicating the correct positioning of container transporters during loading and unloading. The system includes a transmitter (7) which transmits two differently modulated beams (C) (D) of electromagnetic radiation which have a region of overlapping modulation (E) at the correct location. Detection means (8) carried on the transporter (2) are responsive to the overlapping modulation and provide an output to the transport driver indicating the position of the transporter (2).
