Running Line Tensiometers - Cable Line Riders

Line Tension, Speed, & Payout Monitoring
  • Rugged, compact, and accurate cable tension monitoring
  • Tension and Payout sensors located in removable center sheave
  • Quick installation
  • Design validated by F.E.A.
  • High payout / scope line speed capability
  • Standard sizes rated from 10 tons to 500 tons. Smaller sizes are also available.

MTNW recently completed an evaluation of tensiometer suppliers and was particularly impressed with a rugged, well-designed running line tensiometer (RLT) that features an alloy-steel frame with marine grade coating and high quality stainless steel fixtures. Force and count sensors are located in a removable center sheave, allowing for easy installation without the need to cut or modify the winch lines. If future needs change these RLT’s can be just as easily removed for use in other applications.

In addition to our flagship tensiometer line MTNW has recently added additional models to our product line, Single Side Plate Tensiometers, a more cost effective option, and Variable Wire Diameter Tensiometers, a more versatile option.  

Our Single Side Plate Tensiometers retain the durable construction and accuracy of our existing models, with a streamlined design to reduce production costs. Our Variable Wire Diameter Tensiometers provide a versatile solution for customers looking to monitor line tension speed and payout on multiple wire rope sizes without purchasing multiple tensiometers or sheave assemblies.
