The PT90-2H/2DD is a direct drive puller-tensioner capable of pulling or tensioning 1 or 2 conductors with independent controls.
The bull wheels may be coupled for increase pull or tension control.
The PT90-2H/2DD is specially equipped with a heavy duty hydraulic cooler to ensure proper operating temperature of the hydraulic system.
The trailer is equipped with high flotation tires to ease transport over rough terrain or sandy and swamp conditions.
