Tension Stringing Equipment 2X40kn Hydraulic Tensioner




Our SA-YZ2×40B Hydraulic Tensioner serves to string various types of conductors and earth wires. Either one-pull-one or one-pull-two is available.

The infinitely variable tension control system allows this SA-YZ2×40B Hydraulic Tensioner to realize the constant-tension conductor stringing operation. If a hydraulic failure happens, the spring applied hydraulically released multi-plate brake will act automatically. Thus, the operation is made safe.

Furthermore, our product is designed with two sets of hydraulic power output interface, which is able to connect the hydraulic conductor reel stand. Its bullwheel is specially lined with the wear-resistant MC nylon material.



Uses: It's used for stringing various conductors and earth wires, suitable for stringing one conductor or two bundle conductors.

1, Bull wheel with wearproof MC nylon lining segments.
2, Infinitely variable tension control and constant tension conductor stringing.
3, Spring applied hydraulic released brake acts automatically in case of hydraulic failure to ensure safety.
4, Attached two sets of hydraulic power output interface to connect hydraulic conductor reel stand.
