Abstract
A lifting device is configured to support a bridge cap when lifting the cap onto columns under a bridge deck. The lifting device includes an upper bracket arm configured to extend over an upper surface of the deck, and a lower bracket arm configured to extend under a bottom surface of the deck, and to selectively engage the cap. A side bracket portion connects the lower and upper arms, and is configured to transmit a force associated with a weight of the cap to the upper arm. The upper and lower arms and the side bracket portion are configured to define an open space extending from free ends of the upper and lower arms to the side bracket portion. The space is configured to receive the deck when the lifting device is supporting the cap as the cap is being lifted onto the columns.
