The Nano-Lok SRL is a smart safety lanyard to help protect users while working at heights on elevated forklifts. It combines occupancy-sensing technology, smart hook sensors, and an intuitive lighting system to create a novel approach to working at heights safely. The system solves the issue of users not knowing if they are safely tied off by giving them visual and audio feedback on their tie-off status. The highly visible light design also allows safety managers to better observe user safety.
