Preplanning was key in this project to set eight components at a chemical plant in Arkansas, which were added while the plant was in operation. Limited working space required the relocation of several components in order for the cranes to fit in the set location.
The largest component set was a cold box with dimensions of 184’ x 16’ x 16’. It weighed 401,000 pounds.
The crew used a CC2800 in superlift as the main crane. The tail crane was a CC2800, which was used to walk the box to the main crane. The rigging had to be sized precisely to avoid hitting the ladders and platforms that were installed.
The cold box was set next to the other boxes on a predetermined specific pad location. The project, which required more than a year of planning, was completed on schedule.
