Lifting tilt walls

Clayco Corp. is building the world headquarters for Chevron Corp. in Covington, LA. The project will encompass three buildings utilizing tilt-wall construction. The tallest wall to be erected is 68 feet in height. The heaviest wall to be erected is 242,000 pounds. A 300-ton Link-Belt 348 crawler and a 30-ton Link-Belt RTC 8030 are erecting the wall panels. Both cranes are rigged with the L1, 125-ton capacity, 24-foot Super-Bar spreader bars to lift and place the wall panels. Braces are added to the outside walls in order to sustain hurricane strength winds that often hit that region. For information about the Super-Bar system, visit www.super-bar.com.
