Chain Hoist Grid Stand
The Chain Hoist Grid Stand provides a secure attachment of any manual or electric chain hoist to the theater grid steel. With its wide footprint, The Chain Hoist Grid Stand evenly distributes the weight of the load over a large area, helping prevent damage to individual grid channels. In addition, it allows for the load to be dead-hung from the stand, thereby taking the weight off the chain hoist, per manufacturer specifications. As many grids do not have large openings the The unit is bolted together, allowing it to be brought to the grid in sections and assembled in place.

Sapsis Rigging Flies Phoenix in St. John's Cathedral
 Sapsis Rigging provided rigging design and installation services as well as all of the equipment to fly two sculptures in the Cathedral of St. John the Divine in New York City. The sculptures, designed and crafted by Chinese artist Xu Bing , represent a male and female Phoenix flying through the nave of the Cathedral.
Sapsis Rigging Project Manager Michael Sapsis noted, "This project was interesting from start to finish. The Cathedral, which was built in the 1890's, was not designed with rigging points and finding places to support the weight of the two birds was a challenge."
The two Phoenix, which weigh 13,000 pounds each, were suspended from a truss grid which was in turn suspended from 38 chain hoists attached to the building. The truss grid contains approximately 850 ft of 20.5" aluminum box truss and weighs approximately 12,000 pounds, bringing the total weight suspended from the Cathedral roof to 38,0000 pounds.
The Cathedral, located at 112th St and Amsterdam Avenue, is the largest gothic Cathedral in the world. The nave is 250' long and 125' high. Daniel Porter, one the the lead riggers for Sapsis Rigging observed that, "The first hurdle was to get the sculptures into the building." A 50' long X 30' tall loading dock was built from the front of the Cathedral out to Amsterdam Avenue so the crates on flatbed trucks containing the sculptures could be offloaded by cranes. The front doors of the Cathedral were then removed to allow the larger sections of the birds to fit into the nave.
Once inside, the truss grid was assembled and flown into position 60' above the Cathedral floor. Large sections of the sculptures were then assembled on the floor and raised into position and suspended from the truss grid. The entire installation took just under 2 weeks to complete.
"We started discussions about the project over a year ago", Michael offered, "and the serious design and engineering phase lasted 3 months." The sculptures will be on view in the Cathedral for the rest of 2014.
Sapsis Rigging is very honored and proud to be part of this project and would like to thank Michael Sapsis and the SRI installation team; Daniel Porter, Paul Sapsis, Alex Gorman, Daryll John, Nate Doyle, Scott Sloan, the Sapsis Rigging staff and McLaren Engineering for their dedication and hard work in making this project happen.
