Getting The Edge On Safety
The VITECTOR unit of FRABA Inc. has released two new versions of its ‘safety edges’ devices, which are mounted on the edges of large moving objects to provide a warning signal when the object comes into contact with something in its path:
- The first version uses a rubber tube mounted on the edge of the moving object with an infrared light source mounted at one end and a sensor at the other. If the tube is deformed, the light path is blocked and a warning is sent to the control system. The system’s design allows it to distinguish between insignificant events and potentially dangerous collisions.
- The second version uses a sealed, hollow rubber profile mounted on the edge of the moving object and connected to a sensitive pressure switch. When the edge contacts another object, the switch is activated and sends a warning to the control system.
