Properly installed rigging ensures safe and efficient cable installation with a minimum amount of damage to the conductor.
If the rigging slips during a pull, causing the pull to stop, the conductor settles to the bottom of the conduit when the power resumes.
The pulling tension required to move the conductor is much greater than the tension required before the pull stops.
The blocks' diameter should be selected to ensure proper bending radius and installation without damage to the conductor.
The cable manufacturer will provide its recommendations for specific cables and applications.
Conduit Rollers are available to assist the conductor from the conduit to the puller or reel trailer.
This roller is designed to fit the inside of the conduit and provide protection for the conductor as it slides past the end of the conduit.
Lip Rollers are used to assist the conductor over the lip of the vault or manhole without unnecessary damage.
Jamb Skids and Quadrant Blocks are normally used on larger conductor installations. The jamb skid is designed to rest on the floor of the vault and is secured to the manhole.
Feed Tubes assist the conductors from the reel trailers into the vault and conduit.
The round tube helps form the conductors into a triangle shape to allow proper entry into the conduit. Without this tool, normally someone has to assist the conductors into the conduit.
