Specialists of lifting WO Grubb were asked by Smithsonian for moving the considerable remains at the newer National Museum of African American History & Culture. A 45 t railway car was the first one that was lifted. Project Manager Stephen Dieren took this task as a great challenge and because of this reason was very much concerned he said that
“A key challenge of the project was getting the ground-bearing pressures correct for the two Grove all-terrain cranes,”
He also mentioned that “They were both set up approximately 60-feet (18m) from the construction pit to achieve the optimum pressures,”
Event took place at constitution Avenue near National Mall. For accommodating the Grove units’ road was not left open. Cranes were stationed on conflicting sides of 24 meter railway vehicle.
2nd lift was given to guard tower that was utilized in 1930 at the Louisiana State Penitentiary received lifting by GMK7550.
After the success of project Dieren shared with us that his team was working hard for months to achieve their target. “Months of planning and days of prep work were put in to execute this job. Everything went beautifully.”
