The T25-1H/1DD is suitable for tensioning single conductor with infinitely variable tensioning control of the conductor.
The exclusive open-sided canted bullwheel design prevents potentially damaging birdcaging or torquing of the conductor/OPGW. This design also allows for a more compact machine.
The large bullwheel design are fitted with replaceable synthetic lining segments. The T25-1H/1DD provides powered hydraulics for easy reeving of conductor and pullback capability. This unit is mounted on a single axle trailer.
