On safety decals, this symbol and the
signal words Danger, Warning, Caution
and Notice draw your attention to
important instructions regarding safety.
They indicate potential hazards and levels of intensity.
RED - DANGER indicates an
imminently hazardous
situation which, if not avoided, will result in death or
serious injury.
ORANGE - WARNING
indicates a potentially
hazardous situation which, if not avoided, could result
in death or serious injury.
YELLOW - CAUTION
indicates a potentially
hazardous situation which, if not avoided, may result
in minor or moderate injury.
BLUE - NOTICE alerts you to
practices unrelated to personal
injury, such as messages related to property damage.
IMPORTANT: To prevent serious injury or death to
you or your family, it is essential that safety decals
are clearly visible, in good condition, and applied to
the appropriate equipment.
FOLLOW MANUAL & SAFETY DECAL MESSAGES
Carefully read this manual and
all safety decals on your
equipment. Safety decals must be
kept in good condition. Replace
missing or damaged safety decals
by contacting Sukup
Manufacturing Co. via mail at PO
Box 677, Sheffield, Iowa USA, 50475; by phone at
641-892-4222; or by e-mail at [e-mail].
It is the responsibility of the owner/operator to know
what specific requirements, precautions, and work
hazards exist. It is also the responsibility of the
owner/operator to inform anyone operating or
working in the area of this equipment of hazards and
safety precautions that need to be taken to avoid
personal injury or death. Always keep children away
from bins and vehicles with flowing grain.
Make no unauthorized modifications to machine.
Modifications may endanger function and/or safety of
unit. Keep unit in good working condition. Keep shields
in place. Replace worn or missing shields free of
charge by contacting Sukup Manufacturing Co.
GRAIN BIN SAFETY
Owners/operators are responsible for developing
site-specific confined space entry procedures.
OSHA’s confined space entry procedures (29CFR
1910.146) can be found at www.osha.gov.
If you must enter bin for repair or maintenance:
 Use a safety harness, safety line and respirator
 Station another person outside of bin
 Avoid the center of the bin
 Wear appropriate personal protective equipment
 Keep clear of all augers and moving parts
DANGER: Never enter bin unless all power is
locked out and another person is present.
Rotating augers
can kill or
dismember!
NEVER enter bin when augers are running!
When bin is nearly empty, sweep auger will travel at an
increasingly fast speed. Keep away from sweep and
sump augers to avoid entanglement.
Failure to follow precautions above will result in death
or serious injury.
DANGER: Flowing grain
may trap and suffocate. If
you enter a bin of flowing grain
you can be completely submerged
in grain in about 8 seconds.
Failure to heed this warning will
result in death or serious injury.
Read manual before installing or using product. Failure to follow instructions and safety precautions in
manual can result in death or serious injury. Keep manual in a safe location for future reference.

PREPARATION / UNLOAD INSTALLATION
Unload tube can either be placed in a bin with a steel aeration floor as shown in Fig. 3 or a concrete
trench as shown in Fig. 7. Instructions are provided for both types of floor. In either case, the first step is
to determine from which side of bin grain will be unloaded.
Unloading tube must have unobstructed path to center sump, and center of top gearbox must be in exact
center of bin as shown in Figs. 3 and 7. Locate center of bin by taking several measurements.
For installation in full aeration floor:
NOTE: If installing in existing bin with a full aeration floor, it may be necessary to remove about half of
floor.
Before installation, check floor height.
Minimum plenum height required for installation of sweep is:
6" sweep -------- 12"
8" and 10" - 13-1/4"
Maximum floor thickness is:
6" and 8" ----- 2-3/4"
10" ------------- 1-3/4"
NOTE: Instructions
are written for
installation prior to
floor installation, and
for when floor is
arranged as shown in
Fig. 3. Ensure there
are adequate floor
supports used
around unload tube.
Fig. 3 & Table 7

Preparation / Installation
13
Cut hole in bin wall at desired unloading location, with center of hole located as shown in Fig. 4,
depending on size of unload tube.
6” Sweep, cut 6-1/4” U-shaped opening
8” Sweep, cut 8-1/4” U-shaped opening
10” Sweep, cut 10-1/4” U-shaped opening
If floor has not previously been installed, install half of bin floor on side opposite of unload, plus two
planks past center of bin. NOTE: Floor planks must run perpendicular to unload tube.
Position center sump so that center of top gearbox is at exact center of bin. Align center sump with bin
wall opening. With spray paint, mark pattern around sump on floor planks. Cut appropriate size hole for
sump. See Fig. 3.
Position center sump so unloading tube attachment points toward bin wall opening. Support center sump
at bottom, if necessary, using non-flammable material. Place extra floor supports around sump for
additional support.

SUPPORTING FLOOR OVER UNLOAD SYSTEM
DISCLAIMER: It shall not be the responsibility of Sukup Manufacturing Co. to determine suitable support
system for flooring over unload system. Customer (or customer’s retained engineer or construction
supervisor) is responsible. Consideration should include, but not be limited to, live loads, dead loads and
seismic zone. Sukup Manufacturing Co. will not be responsible for any damage to a product, including,
but not limited to, any damage that results from inadequate or improper support methods and materials.
Bridging kits are available from Sukup Manufacturing Co. to simplify installation of flooring over unload
auger and to improve strength and stability of flooring over it. Bridging can be used with Standard or
Heavy Duty Double Super Supports.
Table 8 shows locations where bridging is needed and shows bridging kits available (P5110 or P5111).
If applicable table in flooring manual (for type of supports used under floor) says supports should be
placed closer than allowed by width of center sump gate and/or unload system, then bridging is needed
to support floor planks at sump and/or along unload auger. It is OK to use a Double Super Support in
place of a SuperWave or Z-Post support to get closer to unload system without interference.
See applicable Channel-Lok flooring installation manual for bridging instructions. Fig. 6 shows typical
placement of Double Super Supports and bridging for Sweepway.

For installation in concrete trench:
Ensure trench meets dimensions shown in Fig. 7 and Table 9. Trench will need to be formed when
foundation is poured. Because of moving slide gates and pull rods, concrete CANNOT be poured over
sweep tube. After tube installation, cover trench with Channel-Lok flooring or other suitable material.
Position center sump as shown in Fig. 7 so top of gearbox is at exact center.
For installation in either application:
A concrete pad, 4’ 6” x 4’ measured from bin foundation, is required for unload systems using vertical
boot drive. Pad should be poured below level of concrete floor of bin, as shown in Fig. 8. Use Plenum
Height table to determine pad offset (B) from bin floor. NOTICE: In northern locations, frost can lift pad,
causing damage to unload system. Loosen threaded support legs in winter and re-tighten in spring.

For installation in both floor types:
With tabs on unloading tube closest to center sump, slide unloading tube out slightly through bin wall and
then back into sump. Position tube so intermediate sumps are straight up. Bolt tube to sump using
attachment tabs welded onto tube, and holes provided in sump.
Connect extension sections of auger, if applicable, as shown in Fig. 9.
Slide unloading auger, square end first, through unloading tube and over stub shaft in sump. See Fig. 10.

Using bolts and turning flighting 180°, extension should be lagging, not leading inside section of flighting.
If working in rice or other small grains, bolts may be omitted and shaft can be welded into place to match
flights. Leave a slight gap between tubes to get a good weld on connecting shaft and tube.
Fig. 9
When adding an extension, flighting overlap
needs to be on backside of grain flow. This
will limit wear problems and put least
amount of stress on flighting.
To avoid separating and capacity problems, flighting
should be welded on both overlapping ends.

Slide bin collar over tube protruding from bin. Position bin collar so clutch pull rod hole and lock assembly
are on lower right side as shown in Fig. 11. Collar clamp tabs will be horizontal as shown. Mark clutch
rod hole and drill through bin wall. Using metal screws, fasten bin collar to bin wall. Caulk around collar.
Do not tighten bin collar clamps at this time. If unload system has an independent intermediate sump,
remove knockout for pull rod.
INDEPENDENT INTERMEDIATE SUMP PULL ROD INSTALLATION
Sweepways with 8” or 10” diameter unload tubes manufactured on or after June 1, 2018, are equipped
with an independent intermediate sump. Follow these steps to attach pull rod:
1. Remove four (4) shaft collars from pull rod.
2. Attach a pull rod support clamp about 15” from independent intermediate sump. Be sure to leave
at least 11” clearance for sump gate opening.
3. In bins more than 31’ diameter, attach a second pull rod support clamp about halfway between
first clamp and bin wall.
4. Slide pull rod through support clamps and into gate bracket as shown in Fig. 12, simultaneously
attaching shaft collars to rod as shown.
5. With gate fully closed, push sump rod against sump.
6. Adjust shaft collars so they are tight against gate bracket. Tighten shaft collars.
7. On outside of bin, attach E5404 handle to pull rod using setscrew.
8. Ensure sump gate opens and closes completely.

Slide clutch pull rod through bin collar and into rear compartment of center sump. If not already installed
on unload tube in bin 31' dia. or larger, bolt clutch rod support clamp midway on unload tube and slide
clutch pull rod through support (support not needed in smaller bins).
Attach clutch pull rod to clutch shifter arm with 3/8 x 1-1/2” picker pin and hairpin clip. Use hole closest to
end of shifter arm for 10” unit. Use other hole for 6” or 8” unit. See Fig. 13. See Fig. 14 for overview of
center sump and clutch assembly.
Fig. 14 – Overview of sump w/ pull rod connected
Guide center sump gate pull rod up to 1/2" nut rivet on center sump slide gate. See Fig. 5. Thread pull rod
into nut rivet until tight. Turn nut on pull rod until it is tight against slide gate.
As floor installation or re-installation continues, cut floor planks where intermediate sumps will be located.
Number of sumps varies with diameter of bin.
Put top half of each intermediate sump into hole cut into bin flooring. Secure flanges to flooring with self-
drilling screws. See Fig. 5. Also, ensure bottoms of sump covers extend into intermediate sumps. Sump
covers may have to be trimmed so they do not interfere with sump gate operation.
With all intermediate sumps in position and all sump slide gates operating freely, tighten clamps on bin
collar. See Fig. 11.

Slide 1" lock collar onto clutch pull rod with clutch disengaged (rod pushed in). Push latch down and slide
1” lock collar against bin collar so that when latch is released, lock collar is sandwiched between latch and
bin collar. See Fig. 15. Tighten 1” lock collar setscrew. Latch will keep clutch disengaged. When latch is
pushed down, rod can be pulled for engagement of clutch.
Fig. 15 – Front and side views of clutch lock assembly
NOTE: Clutch is factory-set. However, make sure teeth engage and disengage properly. There should
be about 1/4" clearance when clutch is disengaged. See Fig. 10. Clutch disc may be adjusted by
loosening bolts.
COMPLETING FLOOR INSTALLATION
Complete installation of bin floor, making sure to provide adequate support along unload tube and near
sump. This applies to full-aeration steel floors and flooring over concrete trench.
NOTE: If small, easy-flowing grain will be stored in bin, it is best to seal sumps with silicone or a rubber
membrane (not provided) to avoid leaking.
IMPORTANT: Ensure supports do not interfere with sump gate operation.
NOTICE: Floor flashing must be installed over steel aeration floor as shown in Fig. 16 to prevent
excessive wear on drive wheel. Sweep moves clockwise. Ensure that flashing is overlaid so sweep
wheel “steps up.”
