The 120W Blue spotlight warning light ensures pedestrian safety under overhead cranes by projecting a solid white, blue or red tightly focused LED spot or line on the floor below that alerts pedestrians to an overhead crane's hook location. In addition, the product aids precise positioning for the crane operator with another frame of reference on floor.

24 LED Spotlight warning lights improve safety on overhead cranes:
1. Reduce incidences of human error - ensures pedestrians are aware of moving load.
2. Pedestrian sees projected line or spot on floor - knows his proximity to the moving load.
3. Very effective for overhead cranes in areas with many pedestrians.
4. Beeping audible alarms do NOT provide a pedestrian with a sense of proximity to the load on the crane.
5. Crane operators have a new "frame of reference" of the exact position of load/hook above floor.
6. Significantly improves operator control of the load, especially when exact positioning is required.
7. Operators do not have to take their eyes off the crane block or load to know trolley is centered over the load.
8.Snap-on lens cover creates square "box" around load/hook on floor below clear "danger area".
9. Warns pedestrians from walking under suspended load.
10. When a load on a crane is stopped suddenly
11. Workers concentrating on their job at hand and may NOT see moving load in their area.
12. Crane operators concentrate on the load they are handling and may NOT see workers.
13. Powerful 24 MAXI LED 120 watt light projects RED, BLUE or WHITE spot or line -with lens cover.
