This running line tensionmeter from Straightpoint is a smart way to measure tension, line in/out speed, and distance for wire rope with 5/8"-1" diameter with a 25-ton maximum load rating. It is particularly useful in situations where there is no anchor or dead end on the line to rig a Straightpoint Radiolink or Loadlink digital dynamometer to measure tension force. This particular model (Straightpoint part #TIMH25T & Crosby part #2789137) has an output that connects to Straightpoint's SW-HHP handheld device (sold separately) or Straightpoint INSIGHT computer software (sold separately). For line out & speed, SW-MWLC software is required. This premium 25-ton running line dynamometer is made from corrosion resistant stainless steel and ideal for dockside, marine, offshore, towage, and salvage applications. We also offer a completely wireless running line dynamometer with the same wire rope dimension/load ratings.
