Running line monitors
Running line monitors provide data logging and can measure load speed and distance up to 100 tonnes.
Easy to set up and use, our individual units are designed to suit wire rope sizes and load, and are available for both safe and hazardous areas. For optimal accuracy and repeatability a 5-roller system of operation is applied. Options for accommodating load speed and distance are available and data logging is offered on most variants.
