Spider Suspended Baskets Facilitates Electrical Work on Bay Bridge

Spider, a division of SafeWorks, has been providing suspended access solutions throughout various construction and retrofitting phases of San Francisco’s Bay Bridge, most recently supplying access, fall protection, and training solutions for electrical upgrades.

Spider, a division of SafeWorks, has been providing suspended access solutions throughout various construction and retrofitting phases of San Francisco’s Bay Bridge, most recently supplying access, fall protection, and training solutions for electrical upgrades.

Rosendin Electric faced the task of installing conduit on the western portion of the Bay Bridge. Spider supplied two 11-foot swing stages powered by SC1000 traction hoists, equipped with walk-through stirrups, and customized with 110V transformers that provided a power source for the crew’s tools. The platforms were hoisted 250 feet above the rushing water by crane and expertly secured into position by Spider’s rigging team.

Spider also provided a work basket to access one column’s interior, as well as horizontal lifelines and self-retracting lifelines for fall-arrest protection. Spider also conducted customized Competent Person Training specific to the jobsite.

“Spider’s work baskets, swing stages, hoists and fall-protection equipment have been common sights on the landmark Bay Bridge over the past several decades for various construction, retrofitting and maintenance projects,” said David Beckett, vice president of Spider Operations. “We’re excited to be back on site, safely and reliably getting yet another trade to their work.”

Leonard Morrison, superintendent with Rosendin Electric called Spider’s support “invaluable.” Spider’s equipment is expected to continue on the project throughout the four-month duration of the electrical project.
