Increase Dock Safety
Provide enhanced dock safety by providing inside and outside positive visual communication between the dock personnel and the truck driver, with universal red and green light display. The system includes two light communication systems - one outside on the loading dock wall and one inside the building. When the truck is properly restrained at the loading dock, the dock personnel activates toggle switch mounted on the inside loading dock communication light, changing the inside light to green and the outside light to flashing red. This tells the truck driver not to move during the loading/unloading process. After the truck is loaded/unloaded dock personnel release the restraint, then simply toggle the switch back, changing the inside light to red and the outside light to green, which then indicates to the truck driver he is free to move the vehicle.

Operating Instructions
The truck backs into position against the dock bumpers and set the brakes. We also recommend the use of a truck restraint and also recommend wheel chocks, to secure the truck at the dock. The dock personnel simply toggle the light switch and light changes outside to red and inside to green. When loading/unloading is completed, simply on chock or release restraint and toggle the switch inside the building, the light changes to red inside and green outside, indicating to the truck driver he is free to move the vehicle.
