A clear indication of safety
After an extensive period of development and trial, James Walker RotaBolt has launched the Vision, the world’s first safety bolt to give a clear indication – visible up to 25m away – of loss of tension across a bolted joint. Maintained tension is critical to the safety of bolted joints, and unlike traditional methods of bolt tightening which do not measure tension, the Vision gives a constant and highly accurate tension measurement. The new bolt is primarily designed to make the monitoring of joints in difficult locations very easy, improving safety regimes and making major savings in maintenance. The Vision is based on the award winning integrated technology of the original RotaBolt; but instead of a tactile indicator that requires the operator to ‘finger check’ a special cap on the head of the bolt, the Vision has a specially developed visual indicator which appears as an unbroken yellow line across the head of the bolt. As soon as any tension is lost, the indicator instantly rotates by 90 degrees to show a distinct right angle break in the yellow line. The indicator can be clearly seen from up to 25m away, making it easy to check joints in difficult locations where access is restricted.
