Abstract

An improved pay-off assembly allowing cable loaded on a cable reel to be transported to an installation site and/or paid-off during a cable pull is described. The pay-off assembly may include one or more of lateral support braces that provide stability and strength to an A-frame structure supporting the cable reel; a reel lock assembly for securely holding the cable reel in place during transport and/or pay-off of the cable; an end cap assembly that prevents detachment from an arbor as the arbor and cable reel rotate during pay-off; a dog hole stop assembly that engages a “dog hole” in the cable reel to prevent the cable reel from rotating during transport; a braking system for controlling the rotational speed of the cable reel during pay-off; and a ground attachment assembly that allows an additional cable reel to be loaded for transport and/or pay-off of the cable.
