A computer automated hydraulic hauling unit for transporting precast concrete bridge segments from a casting site to an erection site. The apparatus includes a transportable chassis having computer controlled hydraulic members with means to elevate precast bridge segments from casting forms. The operator sets the lifting and transport parameters in the computer controller from the control panel for elevation and lift control. Each segment is rolled into place on a trailer bed and through automated electronic circuits the hydraulic cylinders apply force to raise the segments onto a movable and uniform beam structure. After elevation to a preselected height each segment is anchored by means of pinning vertical interlocking beams made of high strength structural steel. This computerized hydraulic beam trailer can accommodate one or two segments per load. This apparatus provides construction companies with a safe, automated method to transport precast segments by a self-loading and unloading mechanism that eliminates expensive extra hauling operations.
