Maintenance & Repair Winch | Custom Build for the Richmond-San Rafael Bridge Retrofit
Thern provided two TA5 series Air Winches that were used in the $600 Million project for Seismic Protection of the San Francisco bridge.
The five-mile long bridge underwent structural restoration to address existing earthquake damage and provide it with additional structural support for the future. Our winches were used to help lower old superstructure beams out of position and down onto barges waiting below and to lift new supports into position as part of the reinforcement process.
