These 2 models of work ropes are used for a wide range of applications. Some typical uses for these include:
- General purpose lifting/pulling tool (i.e., lifting or lowering tools or equipment into a work or maintenance zone)
- Hoisting and stringing equipment
- Replacing an FRP tool or hot stick for pulling applications
Yes, we have conducted several lab and field tests with linemen using the Barry D.E.W line dielectric work ropes on sheaves, pulleys, capstans, descent devices and rope grabs. Under normal use, these mechanical tools did not affect the insulative performance of the lines tested.
Please contact us if you have any questions about a specific application or compatibility question for these products.
Our tag lines are offered in standard lengths of:
- 15 m (50')
- 30 m (100')
- 45 m (150')
Other lengths are available upon request, please contact us for more information.
