Steel Components Haul and Set

Barnhart was hired to receive and transport over 40 components ranging up to 732,000 lb. from the Port of Long Beach to a steel forging plant. Barnhart worked with the port to receive the components from ship's hook using SPMT and stage them there on beams and stands. The staging operation also allowed for sequential delivery as needed for the on site assembly schedule.

Over the course of a year, the components were transported by dual lane trailer and suspension girders. The project required over six different trailer configurations which was accomplished by the modular flexibility of the dual lane trailer. The hydraulic trailer also allowed the equipment to be self loaded by Barnhart at the port. The cargo also included several large asymmetrical pieces, which were positioned as needed in Barnhart's suspension girders.

All components were transported to the site on the dual lane trailer. Once at the site, the components were transloaded to SPMT and brought into the new facility where they could be assembled. The team utilized its Modular Lift Tower with strand jacks to make the lifts. On several of the asymmetrical pieces, the CG was not centered between the lifting lugs so Barnhart utilized their extensive inventory of lifting devices to make rigging adjustments as needed on site.

Some larger pieces needed to be bolted together and assembled to a 0.1 mm tolerance using an assembly table made of Barnhart powered rollers and hydraulic jacks. The largest lift, the foundation crosshead, was assembled of seven components adding up to a final lift weight of 4,500,000 lbs. In the end, the team made over 50 engineered critical lifts with very low ground bearing requirements and helped assemble one of the world's largest presses. Despite the scale of the job, it was completed successfully with no injuries or property damage.
