LINESCALE 3i+

The CMC LineScale 3i+ is a high-strength, high-speed load cell designed to deliver accurate, real-time force measurement in rope systems. Used in rescue, rope access, and technical rigging applications, it allows teams to monitor loads during lifting, hauling, and dynamic events with precision and confidence.

Built for demanding environments, the LineScale 3i+ combines robust construction with advanced data capabilities. A clear digital display provides instant on-site readings, while Bluetooth connectivity enables remote monitoring and data logging via mobile app. This allows operators to analyse loads in real time or review performance after operations.

Beyond field use, it is also a powerful tool for testing and training, helping teams better understand system behaviour and improve rigging practices. Its versatility extends to a wide range of applications, including stage rigging, live events, and industrial monitoring.
