Helicopter Lift Golden Gate Bridge
Helicopter lifts Microwave Dish to the top of the south tower of the San Franciscan Golden Gate Bridge.
September 2009, after a couple of weather and technical delays, ARIS Helicopters accomplished a high-profile lift and placement job on the world-famous Golden Gate Bridge in San Francisco. With pilot Samuel Nowden flying a Sikorsky S-58T twin-Turbine helicopter, the job consisted of removing and replacing a twin parabolic microwave repeater disc assembly on the south tower of the bridge.
At 2,500 pounds, the weight of the disc assembly was considerably below the 5,000 pounds the S-58T is capable of lifting. The early-morning lift started with car traffic on the bridge being delayed. Then the helicopter, appropriately named "Engine 58," landed at the toll plaza parking lot. There the rigging was attached new disc assembly and the 100-foot long-line connected to the helicopter.
Incidentally, the disc coming down ended up spinning like a top by the time it reach the parking lot. This was a major concern for the trip back with the new disc. The new 2,500-pound disc assembly spinning that fast would be impossible to handle and endanger the crew on the tower. The decision was made to take it slow and easy on the flight back with the new disc. Fortunately, the slow pace worked, eliminating the spin factor.
This microwave dish (Passive Repeater/Parabolic Antenna) is part of a communications network. Mt. Tamalpais, Big Rock, South TWR GGB, Toll Plaza, San RAF, and San RAF HQ.
