3. Product Overview
Sweep Criteria Recommendations
Congratulations! Your selection of the GSI “X” Series Sweep is a wise investment. It will give you years of
dependable service. The main function of the “X” Series Sweep is to clean out the remaining grain, from
the bin, after all gravity unloading has finished. The GSI “X” Series Sweep is a single pass sweep only.
The unit will only operate in a round grain bin equipped with a center sump in the bin floor.
NOTE: The bin manufacturer should be contacted for their recommendations on the bin’s structural
integrity. The following are sweep criteria recommendations.
Issues Recommendations
Flooring
A track is required under each of the sweep wheels where they travel over the
aeration (steel) floor. The track should be a minimum of 10 gauge thick and made
from steel. The steel can be galvanized for the wheel paths. A
Table on Page 17 is
included that shows radius dimensions locating the points of contact between the
sweep and the bin floor. The dimensions may be used to figure the material
quantities of track to support the sweep across the aeration flooring.
The track
material is not supplied with the sweep and must be supplied by the installer.
The dimensions are approximate and the assembled sweep should be checked for
exact points of contact.
Center Sump Size
When installing a 12" or 16" sweep, the minimum recommended opening is 42" x 42".
The sump hopper supplied by GSI was designed with sufficient clearance around the
collector ring housing to allow grain to gravity flow through the hopper and be carried
away by the material handling equipment below. 42-3/4" is the maximum opening size
to allow rolling clearance for the casters assembled to the head end jack. If made
smaller, grain flow may be decreased to an unacceptable level.
Flow of grain is limited when using this sump and collector ring housing assembly.
The collector ring housing extends 23-1/2" down from the floor surface and is
approximately 14-1/4" x 14-1/4" in size.
Number of Intermediate Sumps
Intermediate sumps must be installed on a maximum of 10' centers where the sweep
will be parked during storage. The first intermediate sump should be placed at a
maximum of 10' from the center sumps and the end sump should be no more than 4'
from the bin wall.
The extra sumps will help clean out the grain in front of the sweep, reducing the
start-up load. Doing this will save labor dollars and hours of work to dig out the sweep
and will help the sweep during start-up. The sweep is not designed to start-up when
submerged in material. The sweep should be parked behind the intermediate sumps
with sumps on the auger side of the sweep.
Routing the Power Supply to
the Sweep
The only option is to use the hopper sump with collector ring. This allows the power
to be transferred through a mechanical device in the center sump and does not twist
any cords.
Floor Level Tolerance
The top edge of the sump hopper and the top edge of the “X” brace support must be
level with the floor. The floor must be level within 3/4" plus (or) minus, preferably less.
Any high or low points must be gradually sloped. The change in elevation should be
no more than 3/4" over 60".
Bin Roundness Tolerance
Diameter tolerances are limited by foundation limits and sweep operation as well as
structural issues. For 72' diameter and larger, the overall tolerance would be plus or
minus 1-1/4" on the radius, plus or minus 1" on 42'-66' diameter bins and plus or
minus 3/4" on 30'-39' bins.
