A "Conductor pulling machine" (often referred to simply as a "puller" or "winch" in underground applications) is a powerful, specialized piece of equipment designed to generate and control the force required to pull electrical conductors or cables through various pathways. Its primary function is to draw the conductor along a specified route.

While often used in conjunction, a "Conductor pulling machine" differs from a "Conductor Tensioning Machine" (OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner) in its primary role:

• conductor pulling Machine (Puller): This machine is positioned at the receiving end of a cable or conductor run. Its main job is to apply a controlled pulling force to draw the conductor from the feeding end. For Overhead transmission lines (OHTL), it pulls the pilot rope, then the conductor, across Stringing Blocks. For underground cable laying, it pulls the cable through conduits, ducts, or trenches.

• Conductor Tensioning Machine (Tensioner): This machine is located at the feeding end of an overhead conductor stringing operation. Its purpose is to apply a controlled back tension to the conductor as it is pulled. This prevents the conductor from touching the ground, damaging vegetation, or coming into contact with obstacles, ensuring a safe sag profile during installation.

In overhead tension stringing, the puller and tensioner work in precise, synchronized tandem. For underground cable laying, a puller is typically the standalone primary machine.
