Abstract
An installation jib for a girder beam installation and removal system includes a main body having a first end and a second, opposite end, the main body extending along a longitudinal axis between the first end and the second end. The installation jib further includes a first sub-frame element coupled to the main body, a first roller coupled to the first sub-frame element, a second sub-frame element coupled to the main body, and a second roller coupled to the second sub-frame element. The first sub-frame element and the second sub-frame element are spaced longitudinally apart from one another, and the first roller and the second roller each are configured to rotate about an axis that is parallel to the longitudinal axis.
