LIFTING DEVICE FOR ERECTING COLUMNS AND RELATED METHOD
A lifting device for erecting a structure having splice plates is provided. The lifting device having a body adapted to engage the splice plates and having an attachment site adapted to be coupled to a hoisting apparatus. The body further has an opening defined therethrough and adapted to align with the plate openings. The lifting device also has a connection assembly comprising a support structure connected to the body and having a cradle, and a releasable connector adapted to extend through the plate openings and the opening. The cradle is adapted to secure the releasable connector through the splice plates and the body when the body is lifted via the hoisting apparatus. The connection assembly also has a disconnection mechanism operable from a ground surface to remove the releasable connector from the plate openings and the opening to disconnect the body and the structure.
