Chapter 1: Safety Precautions
Sharp Edge Hazard
• This product has sharp edges, which can cause serious
injury.
• To avoid injury, handle sharp edges with caution and always
use proper protective clothing and equipment.
ST-0036–2
Toxic Fume and Dust Hazard
• Remove paint before welding or heating.
• Avoid potentially toxic fumes and dust. Hazardous fumes
can be generated when paint is heated by welding, solder-
ing, or using a torch.
• Do all work outside or in a well-ventilated area. Dispose of
paint and solvent properly.
• Remove paint before welding or heating:
— If you sand or grind paint, avoid breathing the dust.
Wear an approved respirator.
— If you use solvent or paint-stripper, remove stripper with
soap and water before welding.
— Remove solvent or stripper containers and other flam-
mable material from area. Allow fumes to disperse at
least 15 minutes before welding or heating
ST-0043–1
Stay Clear of Hoisted Equipment
• Always use proper lifting or hoisting equipment when assem-
bling or disassembling equipment
• Do not walk or stand under hoisted equipment.
• Always use sturdy and stable supports when needed for
installation. Not following these safety precautions creates
the risk of falling equipment, which can crush personnel and
cause serious injury or death.

Chapter 1: Safety Precautions
Avoid Falls During Service and Installation
• Use proper fall protection equipment.
• Anchor the bottom of any ladder being used in a bin or silo to
prevent it from slipping.
• Use rubber pads or other anti-slip devices to prevent the
ladder from slipping on the bin floor.
• Exercise caution when using a ladder to perform work in a
partially filled grain bin. The ladder can sink into the grain
and cause a fall.
• Because the equipment is suspended from chains in the
center, be cautious of positioning the ladder against the
equipment. The equipment can move or swing from the
weight of a person climbing on the ladder.
• When setting a ladder against the equipment, a vise grip or
other type of tie down must be used in the front and back of
the track drive unit. This keeps the equipment from rolling or
sliding around the bin while service work is being performed.
• During heavy service work, such as removing the auger
drive, electric motors, or replacing electrical swivel, tying the
ladder to the main frame or other solid component is
advised.
• Never climb out on the main beam or augers from the ladder
or roof manhole. The equipment can swing, causing a fall.
• Do not climb Stir-Ator down augers to make adjustments or
repairs. Slipping can cause falling, bodily injury, or both.
• If an unusual amount of service work needs to be performed,
consider lowering the unit onto sawhorses.

• Lower sections of ladders must be fitted with a lockable
safety gate to prevent unauthorized access.
• Make sure that hot surfaces have had adequate time to cool
before working on or in the equipment.
• Lock out and tag out power supplies and fuel supplies to all
equipment.

Chapter 2: General Information
Overview
1. All A325 bolts in splice connections are to be tightened by the turn-of-the-nut method. Bracing bolts
are to be “snug-tight” only.
2. All GSI provided steel is hot dipped galvanized per ASTM-123A/123M.
3. No bridge members can be removed at any time unless it was designed for it. Drawings will show
exact layout of members and how they are to be installed.
4. No tower members can be removed at any time unless it was designed for it. Drawings will show
exact layout of members and how they are to be installed.
Required Specifications
1. Steel W sections are ASTM A992, A709 or A572 Grade 50.
2. Steel channels, angles and S sections are ASTM A36.
3. Steel HSS is ASTM A500 GR B, 46 KSI.
4. All structural bolts are A325 unless otherwise specified.
5. All field welds are 3/16 in. (0.48 cm) min. size fillet weld E60XX or E70XX.
6. All grade 8 bolts are to be installed in snug-tight condition.
Hole Preparation
1. Since GSI steels are galvanized, bolt holes may be smaller than the requirement due to the build up
of galvanizing around the holes.
2. The bolt holes are usually 1/16” greater than the bolts in diameter.
3. The holes may be deburred so that the bolt can be inserted through the holes.

Chapter 2: General Information
Elevator Guy Bracket
1. Elevator guy brackets should be installed close to the shear plates on the column.
2. Each bracket should be installed at a maximum of 20 ft intervals to all four columns of the tower.
3. These brackets should be installed only to the columns and not to the horizontal struts or diagonal
braces.
4. These brackets need not to be welded to the columns.
Figure 2-1 Elevator guy bracket
Elevator Guy Bracket Attachment
1. The elevator guy system is used as an internal brace for the tower.
2. If the elevator leg is outside of the tower, the four corners of the leg should be connected to the two
tower columns.
3. If two elevator legs are placed in a single tower, frame the two legs together and brace all four cor-
ners back to the tower.
Figure 2-2 Elevator guy bracket attachment – shear plate locations
PNEG-2115 2-Leg and 4-Leg Towers 15
Chapter 2: General Information
Elevator Guy Bracket Position
1. When possible, the elevator leg should be centered within the tower so that the wind load transmit-
ted to the tower is distributed equally between the two parallel sides of the tower.
2. If the elevator guy is outside the tower, when possible, the leg should be centered between the two
nearest columns of the tower so that the wind load is distributed to the tower equally.

Chapter 2: General Information
Bin Guy Kit for 2-Leg Towers
1. The bin guy kit has a clamp that will fit around the column and a plate that will require field drilling to
the nearest bin stiffeners.
2. The clamp should be attached close to a shear plate.
3. The guy bracket should not be attached at the stiffener splice.
Figure 2-4 Bin guy kit for 2-leg towers
Seal Plate Kit
1. The seal plate kits may not be shipped with every tower.
2. If needed, it is installed on top of each of the 2-leg or 4-leg tower columns to prevent water or trash
buildup inside of the column.
Figure 2-5 Seal plate kits

Chapter 2: General Information
Top Tower Beams
1. The top tower beams can be either in a 2-beam or 3-beam configuration.
2. If it is a two beam configuration, the beams will be one on each pair of legs.
3. If it is a three beam configuration, the beams will appear as shown below.
Figure 2-6 Top tower beam configurations
Catwalk Location
The catwalk is supported in the middle of the tower so that the load of the catwalk is distributed equally
between the two sides of the tower.

Chapter 2: General Information
Tower Erection
1. The tower is assembled vertically with various sections depending on the required height.
2. The tower sections should not be assembled by lifting on the sides.
3. The tower is designed with each section in a specific location, it is critical to assemble the tower with
the correct members in each section.
4. Square each section and then tighten the hardware before stacking the next section.
5. The shipping bolts should not be used in the tower assembly.
