We have recently developed and started selling the Variable Wire Diameter (VWD) versions of our RL10, RL20 & RL30 tensiometers.
These models 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.
The VWD is easily swapped from one wire rope to the next by a single operator by utilizing our Removable Center Sheave feature and Jacking Screws. The RL10 VWD is suitable for wire rope ½” to 1 ½” in diameter while the RL20 VWD is suitable for wire rope 1” to 2” in diameter.
Rugged Controls VWD tensiometers have set the standard for quick and simple tensiometer installation by including a modified Removable Center Sheave. This feature allows operators to quickly install and remove a tensiometer from a fixed line without the need to cut or modify the winch lines.
Our VWDs are suitable for the most aggressive offshore marine applications with anti-corrosive thermoplastic coated Alloy Steel frames. Fully hardened 4340 Alloy Steel sheaves with spherical roller bearings offer high line speed ratings, increased wear resistance and service life. Validated by FEA analysis, our VWD tensiometers offer a 2.5 to 1 ultimate safety factor with +/- 1%FS tension accuracy.
The new VWD version of our running line tensiometers provides operators with more flexibility and versatility when choosing the equipment that will support their requirements.
Features:
- Provides line tension, speed, and payout measurement
- Accommodates multiple wire rope sizes without swapping sheaves
- Minimal downtime - can be installed in minutes
- Precision tension accuracy - greater than +/- 1% FS
- Perfect for spooling projects and temporary mooring projects
- High line speed rating under full load
Typical Applications:
- Spooling
- Offshore Mooring
