Access to a piece of equipment is a frequent challenge in projects, as in this Barnhart job at a fertilizer plant in Iowa to remove a 45-ton catalyst reactor for refilling. Barnhart had to crawl a CC1800 crane down a narrow 30' wide alley to reach and lift the reactor.
Barnhart added a chain fall to accommodate the unusual shape of the 50' tall reactor just in case the CG was off. In the end it wasn't needed, because the reactor was picked level.
Once the reactor was placed on the ground it was refilled with catalyst. Then Barnhart reversed the process to replace the reactor. Despite having little lead time, the project was completed ahead of schedule.
