T50-1H/2DD Hydraulic Bullwheel Tensioner

The T50-1H/2DD is suitable for tensioning one or two conductors 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.

Low tension “bias” control for low tension control – OPGW / Earthwire applications.

The large bullwheel design are fitted with replaceable synthetic lining segments. The T50-1H/1DD provides powered hydraulics for easy reeving of conductor and pullback capability.

This unit is mounted on a single axle trailer with manual parking brake.
