Underpinning Brackets

Standard-Duty Underpinning Brackets for Helical Pile Foundation System

For use with 1¹/2" and 1³/4" square shaft anchors, as specified below, each bracket is identified by the size stamped on the vertical gusset. Brackets also may be used in conjunction with Uplift-Restraint Bracket.

Bracket comes complete with the hardware required for assembly of bracket; does not include concrete anchor bolts.

The lifting assembly, consisting of the underpinning bracket and jacking tool, is designed to lift with hydraulic jack assist as shown below. However, if jack assist is not available, lifting can be done with the bolts of the bracket. The recommended method is to use a hydraulic jack with a load gauge to avoid exceeding the ratings of the brackets.
