Sweet Manufacturing Company assumes no liability in regard to the adequacy of foundations. A qualifi ed engineer should design the foundation of the Goliath® II Tower. Sweet Manufacturing Company will provide tower-loading calculations to the engineer to aid in the design of the foundation.

Your Goliath® II Tower has been designed based on standard design criteria. It is the responsibility of the installer, purchaser, and/or the end user to consider unusual local conditions such as wind, earthquake zones and legal requirements.

The Goliath® II Tower must be assembled using the Grade 5 hardware included with the tower. If you need additional fasteners, make sure they are Grade 5, see Fig. 1. Each bolted connection must be torqued as required, per Table 1.

• Make sure all personnel are provided proper fall protection and have been trained in the use of such equipment, when applicable.• Wear proper protective equipment during assembly.

• We recommend the use of a crane when stacking the stages.

• Do not stack more than two stages at a time.

CHECK AND INSPECT YOUR ORDER

Each order or shipment is double checked before leaving the factory. All parts, pieces, and components are listed item by item on our packing list which accompanies each order. The number of each item is listed on the bill of lading. In signing the bill of lading the carrier assumes full responsibility for the safe delivery of all goods to destination in the same order, as tendered by the shipper. In the event of damage or shortage, have the transportation company driver note the same on the freight bill. You should then fi le claim against the carrier for such loss and/or damage.

You will fi nd a packing list attached to one of the items in the shipment. Check each item against the list. Check by description, specifi cation, quantity or count, etc. Should there be any discrepancies, notify us immediately. If an order or shipment includes more than one support system, the parts for each will be color coded for easy identifi cation.

Small parts and items, such as bolts, and washers are just as important to an installation as the larger ones. Make certain these are located and checked before disposing of any containers or packing. We cannot be responsible for the loss of items that are listed and included on our packing list.

Should there be some delay between the time an order is received and ensuing installation, store parts in a protected area so that they may be easily located and identifi ed. Retain packing lists for this reason as well as for future parts reference. Be certain to verify packing lists against material received before storing for any length

of time.

SELECTION

Goliath® II Towers are specifi cally designed for lateral support of bucket elevators, making the use of guy wires unnecessary. The Goliath® II can be used to support other equipment, such as weigh bins, screens, distributors, etc., however, the tower must be sized for these additional loads.

The Goliath® II Tower is designed to transfer the lateral loads (wind pressure) and vertical loads (weight) into vertical leg loads that are resisted by the foundation. For this reason, foundation design is very important. (SEE FOUNDATION).

When selecting a Goliath® II Tower, several considerations should be addressed; They include, but are not limited to:

1. The proper size needed to contain the bucket elevator and possible future bucket elevators and equipment.

2. Accessibility of the boot for loading. Chutes and conveyor transitions must fi t.

3. Boot maintenance.

4. The tower should extend to the top of the elevator.

5. Are service platforms needed? If so, how many and at what elevations?

6. Depth of pit required.

7. How will the head be accessed for maintenance? Will a ladder on the leg be required or stairs and handrails? (Note, stairs are not available for the 4’ x 8’ Goliath®).

8. Leg area. See Figure 2. Use the larger of either F or 2 x G for wind area. Table 2 gives general recommendations for tower size based on elevator wind area.

Moment = 1000 ft-lbs.Weight = 1000 lbs.Maximum Trunking Width is the largest width of the elevator leg (either “F” or 2 x “G”).

Using a Sweet® Queen model elevator, the “F” dimension is 14” and “G” dimension is 10”. Since the larger of 14” or 2 x 10” = 20”, use 20” as the maximum trunking width. From Table 2 below, a 10 x 10 Standard Duty Tower would be the minimum tower size selected. Depending on your specifi c installation and the answers to the above selection considerations, you may want to select a larger tower.

FOUNDATION

A proper foundation is the key to a successful tower installation. It must be designed by a qualifi ed engineer to withstand the loads and moments applied to it. A typical foundation for 3,000 psf soil is shown in Fig. 3 for reference.

Table 2 can be used to determine foundation loading requirements as a function of tower height, tower size and trunking width. Where additional loads are to be applied to the tower, or heights exceeding 140’, consult the factory.

Anchor bolt design should be per Figure 4. These are either 1” or 1 ½” diameter L shaped anchor boltsconforming to ASTM F1554 Gr. 105 (105,000 psi yield strength). The anchor bolts should be placed in the concrete foundation with approximately 6” protruding. Locate the anchor bolts per Figure 4. At assembly, the base section of the tower is located on these anchor bolts and supported by a washer and nut underneath and above the leg fl ange. Note anchoring hardware is not supplied with the Goliath® II Tower.

An optional foot print template is available to use in locating the anchor bolts in the concrete foundation. See Fig. 6.

TOWER ASSEMBLY INSTRUCTIONS

The Goliath® II Tower consists of stages that are to be pre-assembled in 20-ft heights. These stages referred as A, B, C, D and E, denote the strength and placement of the stages. Stage A is the lightest and is the highest stage in the assembly, where stage D or E would normally designate the foundation or base stage. A typical 100’ Goliath® II Tower may consist of the following: D, D, C, B and A. Refer to the packing list for your specifi c staging.

DO NOT MODIFY ANY STAGE.

The base leg or foundation leg assembly has a square pad to fasten to the anchor bolts in the concrete pad. The other leg assemblies are symmetric, so they do not have a top or bottom. See Fig. 7 below:

We suggest that the Goliath® II Tower be assembled in 20-ft sections, starting with the foundation stage. Only the foundation stage has cross braces on the bottom of the leg. Intermediate staging only has the cross braces on the top and center of each stage. Assemble as shown in Fig 8.

When installing the diagonal braces, notice that they are placed on opposite sides of the base leg fl ange. The diagonal running from lower left to upper right is placed on the outside of the fl ange of the base leg, while the diagonal running from upper left to lower right mounts on the inside of the base leg fl ange. The cross braces attach to the outside of the fl ange. In the center of each leg is another set of holes for the placement of the second set of diagonals and cross brace. Figure 9 shows a typical bolted connection for the tower approximately 10’ from the bottom of each leg. The only change in the connection would be for the stair platform bracket (optional). Please refer to the stair assembly section (or manual) for that information.

The connection at the top of each stage is similar to the center with diagonals and cross braces. If a stair kit is to be purchased, refer to that section (or manual) for location of the stair platform-mounting bracket.

After all the members are assembled to the base legs, we recommend that all the 5/8”-11 grade 5 hex head bolts be tightened to 130 ft-lbs, do not over tighten as this may cause the bolt to stretch and weaken. Fig. 11 shows a typical assembled stage.

After assembling the foundation stage, we suggest starting with the next stage in the tower completing the entire 20’ section. After the section is assembled the stage may be hoisted by crane on top of the foundation staging. Bolt the splice plates of the two stages together using the 1”-8 bolts, fl at washers and nuts supplied, placing the washer on the nut side, and torque to 550 ft-lbs.

If this tower is to be constructed around an elevator, we recommend that the elevator be installed in sections along with the Goliath® II Tower per the assembly manual provided with the elevator. The elevator trunking must be

supported every 20 feet on the inside of the tower. This is accomplished by making a connection from the four outside corners of the casing to the inside of the vertical tower leg. We suggest using our standard guy bracket assemblies, which can be located at any position on the leg casing. Customer to supply either aircraft cable or structural angle iron to complete connection to the vertical tower leg fl ange. It may be necessary to drill holes to achieve desired location. Make sure any modifi cations are made so that the strength and safety are not impaired. See Fig. 13.

PLATFORM

If your Goliath® II Tower requires a service platform, it will be necessary to replace inside diagonals on the tower with the diagonals shown below. These new braces will be placed on the outside of the leg fl ange and both diagonals will then have fl anges pointing outward.

Fig. 14 - Tower Diagonals for Platform

The platform angles are drilled to fi t holes already placed on the base leg assemblies. This only applies if the platform is required in the center of a Goliath® II stage. If the platform is required at an alternate location, the base legs must be drilled for placement of your platform. The preferred assembly method for the platform involves assembling the stage where the platform is required and the platform at the same time. Assembling this way will prevent having to remove structural braces, loosening bolts, etc.

After fastening the platform angles to the legs of the Goliath® II Tower, begin placing the platform decking on the angles. These platform deck pieces span the distance between the two angles and are to be fastened to the platform angles using 3/8” –16 x 1” bolts and whiz nuts. After fastening the decking to the angles, the decking needs to be bolted together every 12 inches using the 3/8”-16 x ¾” bolts, fl at washers and whiz nuts, placing the washer on the bolt side. It is recommended to tighten the 3/8” bolts to 30 ft-lbs. Continue these steps until all platform decking is installed.

Fig. 15 - Decking to Decking Assembly

Page 15: Installation & Assembly Instruction Manual · 2020-01-03 · ALL GALVANIZED BOLTED SUPPORT TOWER Installation & Assembly Instruction Manual Manufactured in the U.S.A. by 2000 E. Leffel

11

After the decking is in place, it is necessary to determine the size of the elevator leg that will be supported by the tower. The decking will need to be cut in the center. This will need to be modifi ed on site by the installation crew. After the platform is cut, place the two formed channels supplied with the platform kit under the decking and perpendicular to the platform decking splices (Fig. 16) as close as possible to the hole, leaving clearance for the elevator leg.

Now we are ready to fasten the handrails, posts and brackets to the platform. When installing these, it will be necessary to cut the handrail in the location for the entryway. This will also be determined in the fi eld. There is an additional post and bracket supplied for this access. Fasten the upright posts to the bracket using the 3/8”-16 x 2” bolts. Place the nut on the pipe side.

Fig. 17 - Handrail Post to Bracket

Fig. 16 - Bottom View of Platform Fig. 16 - Bottom View of Platform with Splice Channels

Fasten the bracket to the platform and attach the toe boards using the 3/8”-16 x ¾” bolts, whiz nuts and fl at washers included with the hardware package placing the fl at washer on the bolt side. The toe board will also need to be cut to allow access to the platform in the same area where the rails were cut earlier.

Fig. 18 - Typical Toe Board and Bracket Assembly

Page 16: Installation & Assembly Instruction Manual · 2020-01-03 · ALL GALVANIZED BOLTED SUPPORT TOWER Installation & Assembly Instruction Manual Manufactured in the U.S.A. by 2000 E. Leffel

12

The platform handrails and intermediate rails need to be secured to the base legs of he Goliath® II Tower. We recommend a 7/16” diameter hole be drilled through the base leg in the required location. Secure the rail using the supplied 3/8”-16 X 2” bolts, fl ats washers and whiz nuts supplied in the hardware package. Place the washer on the bolt side and place it through the rails with the nut on the base leg side as shown in Fig. 19.

Fig. 19 - Platform Rail to Leg

The fi nished tower and platform stage should resemble the one shown.

STAIRWAY ASSEMBLY INSTRUCTI0NS

Some Goliath® II assemblies are sold with complete stairway packages including landings and rail assemblies. The stairway packages are designed to wrap around the outside of the Goliath® II Tower to provide access to the service platforms. It is best to build the stair kit with the erection of the tower and stack the completed stage assemblies. Before assembling the stairway kit it is important to notice there are two different landing support brackets. One is used in the middle of the Goliath® II staging, while the other is used on the top of the tower staging.

13

Fig. 21 - Stairway Landing Brackets

Fasten the landing brackets to the tower locations shown in Fig. 22. These brackets are sandwiched between the base leg assembly and the cross braces/ diagonal braces of the tower. Notice the slots on the brackets. These provide some adjustment of the stairway kit, and it may be desired to only hand tighten the bolts until all pieces of the stairway kit are placed on the tower. After the stair assembly is placed, it is necessary to drill 2 holes through the base leg as shown on the drawing. Attach the platform landing support to the mounting bracket. On the mid stage section, use the lowest bolt hole of each part, the remaining three will line up. On the top of the stage assembly, line up the top holes. Be sure to tighten the bolts after assembly to 130 ft-lbs.

Fig. 23 - Top of Stage Stair Platform Landing Support BracketFig. 23 - Top of Stage Stair Platform Landing Support Bracket

After the brackets are attached, the next step is to assemble and place the platform frame on the landing support bracket using 3/8”-16 X ¾” bolts and nuts as shown in Fig. 24.

Fig. 24 - Platform Base Frame AssemblyFig. 24 - Platform Base Frame Assembly

Fig. 25

Fasten the platform decking to the frame using the supplied bolts. The next logical step would be to install the stairs assembly. The stair risers and rails come pre-assembled. It is necessary to loosen the bolts holding the risers to adjust the stairway to the desired pitch. Be sure to retighten the bolts after assembly. Fig. 26 below shows the stairway assembly as received in the kit.

After the bolts are loosened, the rails running parallel to the top stair riser are attached to the side of the platform decking. Before bolting the side closest to the tower, install the outgoing stair bracket (Fig. 27).

16

The next item to install would be the toe board brackets and toe boards. The kit includes 2 sections of toe board, 2 angle brackets and one corner bracket per stair platform. These are placed as shown in Fig. 28 and fastened with 3/8”-16 X ¾” bolts and lock nuts.

Fig. 28

After the toe boards are in place, install the hand rail posts on both the platform and the stairs. There should be 5 handrail posts per stairway and one for the platform. The fi ve posts for the stairway are 54” long and have multiple holes punched through them. Fasten the posts to the stairs using the 3/8”-16 X 2” bolts and nuts. To prevent possible catch or trip hazards when installing the posts and handrails always place the nut on the outside of the stairway. Fig. 29 is a typical post to stairway connection.

Fig. 29 The platform post has three holes and is not symmetrical. When installing, make sure the 23” bolt spread is on the side closest to the platform. This will ensure the handrails will line up with the rails of the incoming stairway.

Page 21: Installation & Assembly Instruction Manual · 2020-01-03 · ALL GALVANIZED BOLTED SUPPORT TOWER Installation & Assembly Instruction Manual Manufactured in the U.S.A. by 2000 E. Leffel

17

The handrail for the platform is “sandwiched” between the stair handrail post and the handrail. The same applies to the midrail. The platform rails are then attached to the holes in the posts at the bottom of the other stairway.

Fig. 30 - Handrail “Sandwich”

The handrail of the incoming stairs on the left side connects to the left side handrail post of the upward stair kit.

18

The handrail and the midrail for the platform should be bolted to the upright handrail post of the upward stair kit. The completed Goliath® II stage with the stair kit installed can now be stacked on the other stages. The completed stage with stair kit should look similar to the illustration in Fig. 32.

IMPORTANT: EACH GOLIATH® II STAIRWAY SECTION IS RATED FOR 800 LBS. MAX. INSTALL CAUTION STICKERS PROVIDED WITH THE KIT WHERE VISIBLE ACCORDING TO LOCAL, STATE AND FEDERAL REGULATIONS.
