iiconSOUTHEAST rented a new 150-ton 238 HSL lattice crawler from Link-Belt Mid-Atlantic for multiple bridge projects.
From a temporary 300 foot long trestle built within right-of-way space of the existing bridge, the 238 HSL demolishes the old bridge, drives up to 80 feet long piles, and lifts into place new structural beams.
The batter pile angle is set using one template guide just above water level, and a second ten feet above. Two bridge abutments and five piers support a six span concrete girder bridge, with each pier consisting of six piles and a pier cap. For pile soil displacement, a vibratory hammer with 8,000 pound capacity force is attached to a tubular stem for pilot holes prior to pile installation.
