In use, the receiver 14 is attached to the kelly bar 18 of the drilling rig 20 and each of the spokes 16 is adjusted to a length to facilitate each of the bolts 74 to extend through the slot 86 in the central member 78 associated with a respective bolt jig 72. Each bolt 74 is fastened to the central member 78 with a nut 120 threaded on the bolt 74. The first rod 94 associated with each of the yoke supports 88 is adjusted to an appropriate length to align the second rod 102 associated with each of the yoke supports 88 with a respective connection point 116 on the concrete form 92. Continuing, each of the second rods 102 is adjusted to an appropriate length to facilitate the yoke 108 associated with each yoke 108 support to straddle the respective connection point 116 and the second pin 118 is inserted through the yoke 108 to attach the yoke 108 to the respective connection point 116. In this way the bolt cage 76 and the concrete form 92 can be manipulated as a single unit with the drilling rig 20 for positioning the bolt cage 76 and the concrete form 92 in a piling 122 prior to pouring concrete into the piling 122. In this way the bolt cage 76 and the concrete form 92 can be quickly and precisely positioned in the piling 122. The nut 120 on each bolt 74 is removed and the yoke 108 associated with each of the yoke supports 88 is uncoupled from the concrete form 92 when the concrete poured into the piling 122 has cured to facilitate the hub unit 12, the bolt jigs 72 and the yoke supports 88 to be lifted from the concrete form 92 and the bolt cage 76.
