Electrical underground wire pulley to assist in pulling wire through underground conduit

An electrical underground wire pulley for pulling wire through an underground conduit exiting through the top of a base structure having pre-installed anchor bolts spaced at 90 degrees surrounding the conduit, the electrical underground wire pulley comprising:

• a) a frame having a front, a back and opposing sides, the frame being established with;
• i) a bottom universal adapter plate provided with,
• (a) an opening for the conduit, and
• (b) a set of four slots equally angularly spaced about the conduit opening to receive the anchor bolts for securing of the wire pulley onto the base structure therewith, the slots extending lengthwise at 90 degrees from one another in a direction radially outwardly from the conduit opening, the slots being sized to accept the anchor bolts pre-installed on a bolt circle diameter of between approximately 7 to 14 inches;
• ii) a pair of side support elements located on said opposing sides and extending upwardly from the adapter plate,
• at least one of the front, the back and the sides of the frame being provided at a height less than the height of the side support elements to provide access to the opening and the slots from outside the frame;
• and
• b) a pulley rotatably carried between the side supports of the frame for free rotation about a horizontal axis, the pulley being positioned above and generally centered behind the conduit opening for positioning of the curvature of the pulley approximately vertically aligned with the adjacent side of the conduit when the wire pulley is secured onto the base structure.

A method for pulling wire and cable through an underground conduit having an opening at the top of a base structure, the top of the base structure having four pre-installed anchor bolts generally centered about the conduit and equally spaced at 90 degrees from one another, the method comprising the steps of:

• a) providing:
• i) a frame having a bottom universal adapter plate with an opening to receive the conduit and a set of four slots equally angularly spaced about the conduit opening to receive the anchor bolts, the slots extending lengthwise at 90 degrees from one another in a direction radially outwardly from the conduit opening, the frame further having a pair of side support elements extending upwardly from the adapter plate;
• and
• ii) a pulley rotatably carried between the side support elements for free rotation about a horizontal axis, the pulley being positioned above and generally centered behind the conduit opening;
• b) positioning the frame and pulley into a position onto the top of the base with the open end of the conduit positioned in the opening in the adapter plate, with the anchor bolts extending through the slots in the adapter plate, and with the curvature of the pulley approximately vertically aligned with the adjacent side of the conduit;
• c) securing the frame and pulley to the anchor bolts in said position;
• and
• d) threading a starter cable through the conduit, the starter cable having a first end extending through the conduit at the base structure and having a second end connected to the wire;
• and
• e) pulling the starter cable over and around the pulley to pull the wire through the conduit.
