  2. Introduction • Cable s supply power to the ships • Cable spools are currently stored on the ground • They are getting damaged due to the sun, weather, & waterfront activity • Safety hazard • Disorganized • Spools in front are being used more than those in the back

  3. Problem Definition • Racks need to be adaptable to different sized spools • Cables must be stored in the allotted area • Forklift will be used to load & unload the rack http://www.google.com/imgres?imgurl=http://chinadigitaltimes.net

  4. Design Details • Constructed of structural steel I-beams & square tubing • 2 levels of storage available • Forklift accessible from both sides • First in-last out or first in first out spools picking, ensures all spools are utilized • Portable building can be added to protect from the elements

  5. Solidworks Model

  6. Environmental Protection • Portable Building • Polyolefin Covered Shelters • 5-8 yr lifetime expectancy • Bolted construction, to withstand up to 70 mph winds • Can be manufactured to withstand up to 110 mph winds • Flame retardant, UV, & mildew treated • 5 year pro-rated warranty http://1southerncomfortshelters.com/services.nxg
