Overhead Crane Safety Systems: Warning Lights and Indicator Lights
Indicator lights provide a visual warning to pedestrian and motorized traffic in the immediate vicinity of the crane. They indicate the motion of the crane, as well as the location of the hook and/or load to anyone on the ground.
Warning lights and indicator lights can be built into the design of an overhead crane to provide personnel on the ground with an idea of where the crane bridge is overhead and where the hook will be. These lights are automatically on when the crane equipment is turned on and running—helping to reduce accidents and operator error.
These bright red, blue, or white lights are mounted on the bridge or hoist of the crane and project directly onto the ground using lasers, LED lights, or a combination of both. The warning lights don’t take place of audible alarms, but provide an additional visual warning to pedestrian and motorized traffic in the immediate vicinity of the crane. These lights can illuminate an area up to 15 to 20 feet from approaching hooks and crane equipment in operation.
Operators can also use these lights as a point of reference tool to help them position the hoist and hook to make their picks or position a load.
