The Magnum MP1030-175 lifting bracket has 40 tons maximum ultimate capacity, 20 tons working capacity in compression. The bracket consists of a 14? wide gusseted angle with 4 thru holes for attachment to existing concrete using 5/8? concrete expansion anchors. The bracket is designed in accordance with ICC-ES document AC358 as well as IBC, ACI, and AISC codes. Pile layout and connection to concrete varies by project and is the
responsibility of registered design professional including maximum concrete span between piles, concrete shear, concrete punching, and concrete bearing. Note that square-shaft helical piles offer little to no bending resistance; thus, structure to which bracket is attached must be laterally and rotationally stable.
Prepare the existing foundation by chipping the footing (if applicable) flush with the foundation wall. Attach the bracket with four 5/8″ Hilti Kwik Bolt 3’s (or equivalent). Excavate under the bracket at the pier location so the helix bearing plates fit below the existing foundation and the shaft is as close as possible to the face of the bracket. Install the helical pile at 3 deg from vertical to the correct depth and torque. Cut-off the helical pile shaft at 1? to 6? above the bracket gusset plates (as required for lifting). Connect the helical pile to the bracket by sliding the T-Pipe down the shaft; force the T-Pipe toward the bracket face and lock into position with the 5/8? hex bolt and nut provided. To lock-off the pile, simply tighten the two hex nuts located above the T-Pipe. Otherwise, use Magnum? MP1031 Lifting Accessory to pre-load the pile to
specific pressure and/or to lift the foundation.
