T75-2H/2DD Hydraulic Bullwheel Tensioner

The T75-2H/2DD is capable of tensioning 1 or 2 conductors with dual hydraulic infinite variable tensioning control allowing independent control of each individual conductor.

The bullwheels may be coupled for increased tension control with the capability of full pullback of each conductor at slow speed. 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 trailer is equipped with high flotation tires suitable for pulling the unit through sand or swamp land conditions.
