Design Concepts

Static Rack

- No moving parts

- 4-Cell design

-  Sturdy, simple construction

-  Bolted connections for easy disassembly

-  Some welding required

Design Concepts Dynamic Rack

- Moving Parts

- More involved construction

- Bolted and welded connections

- Damper mechanism

Design Direction Static Design

-  Cheaper to construct

- Negligible maintenance

- Easy to repair

- Safer

- Approximately the same spool capacity as the Dynamic Rack

Design Conditions Increase Accessibility Increase Capacity Reduce exposure to the elements

Connections Both welded and bolted connections End plate to distribute loads applied to HSS

Column I-beams are bolted for easy assembly and

disassembly
