Pfannenberg’s Signaling Solutions Provide Efficient, Safer Environment for Overhead Cranes


Modern Industrial Audible and Visual Signaling devices that preserve lives and prevent injuries are vital for critical Industrial Safety!

The Challenge…

One of the largest independent rail car repair shop networks in North America wanted to create a safer environment for their employees. They needed a way to alert workers to the presence of their 25-Ton overhead cranes as they moved near their work area. They approached their material handling partner to help them create a safer environment.

The Solution…

Having had experience with Pfannenberg signaling products the material handling company presented the customer with a  PATROL PA 10 and a PYRA PY X-M-10 to go on each of their two overhead cranes. The recommendation for two devices is to offer a visual and audible warning as the cranes are in motion.

To ensure the best solution, our PATROL PA 10 audible alarm was chosen because it offers the ability to produce 80 different alarm tones with 4 stages. A unique tone was chosen for each crane so the workers can distinguish one from the other without being distracted from their work.  This creates not only a safer environment, but also a more efficient one.

After the horns and strobes were installed, their customer offered the following:

“We currently have two 25 Ton bridge Cranes at our facility, it is a very loud and has low visibility. Our workers were having a hard time seeing the cranes move and also could not hear them either. Pfannenberg’s lights and sounders were recommende to be installed on our cranes as an audio/visual warning system so our workers would be aware of the crane movement. This system has accomplished this task.” – Rail Repair Shop
