Operation

A trailer is backed into position against the dock bumpers; brakes are set. The dock attendant uses the activating button on the control panel to raise the restraining arm. The restraining arm will move in a vertical arc along a reinforced T-rail until it contacts the rear impact guard. The outside light changes from green to red when the STAR 4 is activated. The inside light changes from red to green only after the hook-mounted sensor bar indicates contact with the rear impact guard. If the hook does not contact the rear impact guard, the inside light changes to a flashing red and an alarm sounds. When loading/unloading is complete, the dock attendant uses the release button on the control panel to store the unit. The inside light immediately changes to red when the release button is pressed. The outside light changes to green when the hook has been lowered to the stored position.

Communication

  • Exterior instruction sign for truck drivers
  • Operating instructions printed on control panel
  • Patented sensor bar automatically senses and communicates the actual contact between the throat of the restraint arm and the trailer’s rear impact guard
  • Interior/exterior red & green LED communication lights
