The PT75-1H/2DD is a direct drive puller / tensioner capable of pulling or tensioning 1 or 2 conductors with infinite variable linepull and tension.
The bullwheels are exclusively open-sided canted bullwheel design that prevents potentially damaging birdcaging or torquing of the conductor. This design also allows for a more compact machine.
The hydraulic circuit includes two-speed hydraulic drives that includes a low-tension mode for stringing OPGW and earthwire.
Two auxiliary hydraulic circuits allow remote reel stands or reel winders to be operated directly from the control panel. The control panel includes built in reel stand controls.
The trailer is equipped with a pintle style tow eye and high flotation tires suitable for sand or swamp land conditions.
