Data Sheet

SKU: MP1039-3_ Category:


The Magnum MP1039-3 pivot angle bracket has 50 tons ultimate capacity, 25 tons allowable capacity in compression and tension. The bracket consists of a collar tube with (3) 3/4″ threaded bolt holes for connection to Magnum helical piles and Magnum push piers and bolt holes for attachment to existing concrete using expansion anchors. The bracket is designed in accordance with ICC-ES document AC358 as well as IBC, ACI, and AISC codes. Design and detailing of the connection to the structure varies by project and is the responsibility of registered design professional including maximum concrete span, pier spacing, concrete shear, and concrete bearing.

Installation Notes:
Prepare the existing foundation. For steel push pier applications, prepare the structural steel for welding, then attach the bracket and Magnum ram. Install the push pier to the required pressure and load test. For helical pile applications, excavate 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 foundation. Install the helical pile to the correct depth and torque. Prepare the structural steel for welding, then mount the bracket and install the sleeve. In both cases, lift the structure as needed using either a Magnum ram or lifting fixture. Drill holes and bolt the bracket to the pile.

*Bracket connection to pile consists of field threaded blind bolts as described in Section 7-13 of AISC Code. Capacities shown are based on IAS accredited laboratory testing of Magnum products.
