Abstract:
1. An apparatus comprising two units usable together or separately for guiding conductor/cable during pull in and out from a conduit, manhole or chamber within, the range for pulling force and radius of curvature, recommended by manufacturer, the apparatus comprising: (i) an upper unit comprising three sheaves/rollers installed between two plates creating a 90 degree angle with multiple holes; (ii) a bottom unit comprising three sheaves/rollers installed between two plates creating a 90 degree angle with multiple holes; (iii) an upper adjustable leg mounted on the lower section of said bottom unit; wherein said multiple holes of said upper unit facilitate the bolting of said bottom unit to said upper unit and the installation within the opening of the manhole or chamber and secured outside of the manhole or chamber opening using two square horizontal supports tubes through square holes on a base plate of said upper unit which spans across the opening and secured to the underside of the manhole opening using J hooks or bolts for anchoring into the collar of the chamber or manhole which eliminates the possibility of the entire unit falling into the manhole or chamber and reinforcing and stabilizing said unit for guiding the conductor/cable in and out of a manhole or chamber and; and wherein said multiple holes in said bottom unit are configured to facilitate the horizontal adjustability through angles ranging from 90 to 180 degrees and a vertical alignment by bolting to said upper unit inside a manhole or chamber and secured by means of slings tied to a tie point on side plates of said bottom unit and anchored to a side wall and/or floor; and wherein said adjustable leg is extended up to the underside of said manhole or support tubes which provide reinforcement and stability for said bottom unit and providing guidance for conductor/cable in/out said conduit and provide a secure installation of the apparatus within the applied force during pull in/out operations.
