T180-4H/4 Hydraulic Bullwheel Tensioner

The T180-4H/4 is capable of tensioning 1,2,3 or 4 conductors with infinite variable tensioning control.

The bullwheels are independently controlled with the ability to be coupled to increase tension capability. The machine is also capable of full pull-back at reduced line speed.

The trailer is equipped with high flotation tires suitable for pulling the unit through sand or swamp land conditions. The frame is fitted with a single point lift to allow lifting with a crane.
