Stack Access: Internal Stack & Chimney Access
Tampa, FL
Contractor: Tampa Electrical Company (TEC)
Project Scope
Provide access to internal surface of the stack.
Challenges
- Stack bottom was unusually sloped at 45 degree angle and was severely rusted.
- The stack was 300 ft (91.4 m) above grade and the only access to the stack was at elevation 200 ft (61 m) from catwalk.
Solution
Spider engineered a circular float with a custom rigging star, powered by six 1,000 lb. (453.6 kg) hoists and rated for 4,000 lb. (1,814.4 kg) capacity. Spider’s solution came in under budget and saved the customer $150,000 compared to built-up scaffolding options.
