Abstract
A signaling system includes a rotatable arm connected to a dock. One end of the arm has secured thereto two signaling paddles of distinct visual indicia. The other end of the arm is biased against the underside of a lip plate of a dock loader. As the lip plate is pivoted relative to the dock, the arm is rotated, thus rotating the signaling paddles attached thereto.
