Marr Crane & Rigging Visits the Museum of Science, Boston
In early August, the Rigging Division of Marr Crane & Rigging got to enjoy the electric slide at the Museum of Science, Boston. In the Theater of Electricity, Marr provided rigging services to assist in moving a 1,500-pound metal bird cage, which is used during live presentations, so the hydraulic piston and shaft that elevates the cage could be replaced. Joe Carter (Foreman), Bernie Egan-Mullen and Conor Smith installed 66 inches of cribbing and 20-foot metal beams on each side of the 9-foot-tall cage to temporarily lift it up and slide it to one side. Once the replacement was completed, the cage was moved back into place on center centage, where it will once again be zapped by lightning bolts with the help of the Van de Graaff generator.
