OVERVIEW
Take time now and review the entire assembly manual. A few minutes now could save hours later during
assembly.
Check BOM against parts shipped and report any shortages now before assembly starts.
Foundation is critical for the structural integrity of the tower. Be sure to follow foundation design. A local
engineering firm should review site, soil conditions and foundation design before work is started. Local
codes may require the design stamped by a licensed engineer .
Depending on your work environment, these instructions may need to be altered to best fit your needs.
Assemble tower on a level horizontal surface. Block up column sections high enough to be able to place
horizontal angles under columns and attach with hardware provided. Note: V ertical “X” bracing must be
placed between column and H-Brace. Internal X-Bracing is used at every 5’ of vertical height. Bracing
attaches to the H-Braces.
Attach column splice plates to outside of columns using 1/2" hardware provided. Use splice on both outside
surfaces.
One style of assembly is to build 2 sides laying approximately 48" apart. Rotating sides up attach horizontal
bracing for proper spacing between sides. Keep sections small enough to handle easily. Slide section ends
together and splice together.
Once all sections have been assembled, align and string columns for straitness. Tighten all hardware, columns must be straight!!!
Layout parts for ladder package & service platform. With tower assembly complete & hardware tightened
proceed with attaching service platform & ladder sections. Refer to page 33 that shows general layout of
ladder, safety cage, & plat form. Use the layout that corresponds to the height of tower. Any tower over 30'
must use offset platform included with ladder package. Before starting ladder assembly give some consideration on how to raise tower and attachments to provide safe setting of tower. Some floor planks may need
to be left out until tower is stood in place.
Assemble service platform and attach to top of tower. Place opening of service platform on side of tower
that will have ladder. This will align ladder placement. Attach ladder from service platform towards bottom of
tower. Be sure and use the 10’ ladder access weldment in conjunction with the service platform. Follow the
general layout using the proper ladder section as you proceed. Offset platform is used only on towers over
30’ tall. Follow details for offset platform for proper attachment.
