“THE SYSTEM” for easy matching of tension stringing equipment  

“THE SYSTEM” offers a simple way to specify a matched package of pulling and tensioning equipment for construction of electrical distribution lines in most common conditions. Listed are four project schematics identifying the types and configurations of equipment we recommend for:

  • 4-drum puller methods
  • small conductor systems
  • medium conductor systems
  • large and sub-transmission systems

Each “system” is versatile and complete package of equipment for completing your installation project. Consult THE SYSTEM first, then consult your Timberland technical representative to review any special requirements of your application.

The "Polemaster" pilot line winder allows four pilot ropes to be installed before the pulling process begins.  The pulling rope is pulled to the conductor with the pilot rope (by mounting the polemaster reel on a truck shaft or a rewind on the tensioner), the conductor is installed with the pulling rope, then the pulling rope is immediately retrieved by the rewind for another conductor installation.

Application Guidelines

 

4 Drum Puller Method

This method utilizing our DP20-4H – FOR puller is ideal for stringing distribution conductors up to 795 MCM with 225 foot spans and 4 feet of sag. Smaller conductors may be installed on longer spans.

This "System" is normally used for 8,500 feet and shorter conductor installations. The Four Drum Puller system is very productive for "new" construction as it allows for the deployment of all four pulling lines in one trip down the right of way.

Small Conductor

Our Poleboss Puller/Reel Brake Tensioning system is receommended for installing conductors up to 556 MCM. Smaller conductors may be installed on longer spans with this "System".

This 'System' allows for up to four pulling lines to be deployed at one time and to be pulled back one at a time. Because of it's size, the Poleboss allows easy access to congested areas, backyards, etc.

Medium Conductor

Our DPT-30B Drum Puller/Bullwheel Tensioner system with the Polemaster pilot line winder is recommended for installing conductors up to 795 MCM with 350 foot spans and 4 feet of sag. Smaller conductors may be installed on longer spans. 

This "System" is normally used for 6,000 feet and shorter conductor installations.

Large/Sub-Transmission

Our DPT-40B Drum Puller/Bullwheel Tensioner system with the Polemaster pilot line winder is recommended for installing large distribution and sub-transmission conductors up to 795 MCM with 350 foot spans and 4-1/2 feet of sag.

This "System" is normally used for 6,000 feet and shorter conductor installations
