A Proximity Warning Alert System (PWAS) is generally the term used for a system that warns industrial vehicles that they are in close proximity to a pedestrian worker. Most systems can be fitted to forklifts, reach stackers, gantry cranes, you name it – if these vehicles work near pedestrians, they need a warning system.
When accidents occur with a vehicle, pedestrians are the most at risk. Accidental collisions often occur when a pedestrian is not aware of a vehicle working close by. This is common in busy or loud working environments. The damage caused to a person by a forklift can often be severe, even fatal.
A Proximity Warning Alert System (PWAS) is more reliable. it uses radio frequency identification (RFID) technology that creates detection zones around vehicles, assets, crossing points and walkways.
