Line tension monitoring

James Fisher Strainstall’s (JF Strainstall) line tension monitors provide a versatile solution for customers looking to ensure that mooring and winch loads remain within safe working limits.

We design and manufacture two types of line tension monitors; the Running Line Monitor (RLM) and the Static Line Monitor (SLM). These rugged, compact and accurate units are perfect for applications where a fixed means of measuring is impractical.

Featuring high quality stainless steel fixtures and an aluminium frame with marine grade coating to prevent corrosion, JF Strainstall’s line tension monitors are built to last. Their rugged construction makes them ideal for operation in the most extreme environments, including marine, offshore and onshore applications.

Available to suit various rope sizes and capacities, the line tension monitor’s simple clamp design makes the units easy to retrofit and move for use in other applications. Measuring tension, pay-out and speed in real-time provides customers with maximum flexibility in line control, sensor calibration and data logging.

Static line monitors are compact and measure loads up to 50 tonne’s, whereas our running line monitors provide data logging and can measure load speed and distance up to 100 tonnes.
