Draft Tube Access at Jones Bluff Powerhouse Dam – Selma, AL

Facility Owner:

Spider provided safe and reliable access for maintenance and inspection of the draft tube work at the Jones Bluff Powerhouse dam on the Alabama River. With a very limited access door into the draft tube, Spider engineers designed a custom rigging solution to support the ST-26 Mini Spider basket – the only equipment on the market compact enough to fit through the small entry and still accommodate two workers inside the draft tube for improved productivity. A Limited Space Rescue Winch (LSR1) provided a means to extract the ST-26 in case of emergency. USACE employees completed Spider's Rigging Training and Basic User Training to ensure the safe, efficient operation of equipment.
