Before You Begin

Read the entire installation manual and study the standard detail drawings
supplied with shipment.
Check the packing list for parts received and make sure you have everything listed before
signing off on the packing list or bill of lading. Chief Industries, Inc. must be contacted within (7)
seven days after delivery if there is a shortage of parts.
Unloading:
When unloading the truck, layout various components according to the
number identification and accessibility to the construction site. The following describes the
basic order in which the components will be assembled.

Diagonal Bracing
Horizontal Bracing
Internal Cross Bracing / Access Bracing
Stairs and Platforms
Proceed in similar fashion for bay at next elevation
Storage of Materials:
All galvanized items should be protected from weather and
moisture condensation to prevent the formation of white rust. Small parts, such as
bolts, nuts, washers, etc., are just as important to an installation as the large ones. Make
certain these are located and checked before disposing of containers or packing.
Ideally, these items should be stored in their shipping containers until ready for use on
the project. They have been packaged to protect against moisture and each container is
identified as to its content. Sheet steel should be stored with one end low to prevent
moisture condensation. Chief Industries, Inc. shall not be held responsible for
materials that are not protected or stored properly after delivery.
Claims for Shortages or Damaged Parts:
All claims for shortages or damaged parts
must be indicated at the time of delivery. An authorized representative of the
contractor must be responsible for checking the material as it is unloaded from the
truck. If material is unloaded at the building site, and the installation is subcontracted,
we recommend that the contractor be informed of his responsibilities. Signing the
packing list is your confirmation of complete shipment. If delivery is incomplete or
damaged you should promptly file a claim with the delivering carrier. For shortages
determined upon receipt of shipment, a back order will be immediately issued and
priority given for earliest possible delivery. Shortages determined after acceptance of
materials will be handled as a special house order and will be given priority for earliest
possible delivery. The customer will be charged for these materials. If he receives an
allowance from Chief Industries, Inc., his account will be credited. Chief Industries,
Inc. liability in regard to shortages is limited to supplying the missing materials

Strength Staging Layout
All tower components such as posts, diagonals and horizontal braces are strength staged
according to six (6) different stages. As a result, each tower component has a different
designation. You must build your tower according to the directions supplied and stage the
components as specified.
A components stage designation determines where that specific component will be
positioned. The higher stage numbers indicate higher strength and will be assembled at the
tower base. The lower stage numbers will be assembled at the tower top. The rest of the
components are assembled in stage numerical order in between. Posts, diagonal bracing and
horizontal bracing are staged separately from each other.
Before you start refer to the staging layout drawing attached with shipment and sort the
tower components according to type and stage, in the order they will be used during
construction.
Shown below is an example of a staging layout. This is an example only – you must follow
the staging layout custom supplied with your order.

Catwalk to Tower Connection
Before starting make sure you have a copy of the packing list, this will assist you in
identifying the correct part numbers required for your system.
All local, state and federal safety regulations and requirements must be strictly observed
and enforced.
Installation is largely a matter of individual choice and experience. The following
general outline is provided for reference only.
Note: Leave all hardware (bolts, nuts, washers) loose until all components in a single
bay have been added. This will allow you to square and plumb each bay and ensure
that tolerances do not accumulate.
Note: Bolt heads are to be installed inside of the Tower bay.
Verify the correct tower type / style by looking at the weld dots located near the end of
the Tower posts.
1. Clamp the side weldments to the tower posts top and bottom with the
supplied clamps as shown in the following illustrations. These
connections will require (8) 3/4” x 2” Grade 5 bolts with lock washer and
nut.

Access Bracing
The catwalk to tower connection can be used
with access bracing (purchased separately).
Access braces are installed in a tower whenever
equipment is installed through the tower, or
when the diagonal bracing may interfere with
the proper placement of spouting or other
equipment. Access bracing may also be
installed for personnel access to specific areas
of the tower. A-access bracing shown but Zaccess bracing available as well.
Note: Caution should be exercised when installing access bracing. Only remove
