TOPTREE | What Do The Lights On A Crane Mean?


Operators use crane warning light as a reference point in positioning the hook and hoist to either position a load or make their picks. Crane warning lights are built into its design to provide all the personnel on the ground with a rough idea of where the hook will be and the crane bridge is directly overhead.

Whether you’re considering upgrading or modernizing your older crane system, or you’re designing the specifications for a new overhead crane system, your number one goal should be to improve the safety of the overhead crane equipment and production processes at your facility.

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.

OSHA 29 CFR 1910.179 requires the use of warning lights for any cab-operated overhead crane.
