2 Introduction “The goal of this project is to design a rack to store various sized spools that contain expensive power cables.” Cables 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 Design Parameters Area 120’ x 84’ Ground is relatively flat; an exception is where the drain is located Maximum height forklift can handle ft Blades 8’x 8” wide x 3” thick, 25K Forklift 15’ long x 8’ wide

4 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

5

6 Grey & Yellow Spools

7 Design Details Constructed of structural steel I-beams & square tubing Welded connections 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

8 Forklift Attachment

9 Single Unit Cell

10 2x2 Structure

11 Side View of 2x2

12 Environmental Protection Warehouse Storage Likely means of storage Portable Building Alternative means of storage 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
