10 12" & 16" Series II Sweep PNEG-720-G2
Introduction
There are three (3) options for routing the power. The most used option is
to run the cords out the door in the sidewall. Another 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. This method is popular overseas. Last, is by using the pivot kit,
which routes the power cord through the center sump. Using this kit
requires the sweep to be backed up to the start point after sweeping. The
pivot kit is not the preferred choice due to the cord twisting repeatedly.
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".
Diameter tolerances are limited by foundation limits and sweep opera-
tion 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 ¾” on 30’ – 39’ bins.
The tail section is the largest piece of a standard Series 2 Sweep. The
dimensions for a 16" tail section are 23 1/2" x 55 1/4". If the bin wall is
not too thick, this unit should fit thru a 23 1/2" x 47" opening. The dimen-
sions for a 12" tail section are 21 1/4" x 51 1/2" Again, if the bin wall is
not too thick the section should fit thru an opening 21 1/2 x 45"
GSI offers a special Knock Down Sweep, uniquely designed for storage
units with small doors. This sweep is broken into 10 main pieces that can
fit through a door as small as 30 1/2" in diameter for 16", 27 1/2" in diam-
eter for 12", or a 20" x 24" rectangular door. The components are then
assembled inside the storage unit.
Electrical controls and wiring should be installed by a qualified electri-
cian. The motor disconnect switches and conductor cables should comply
with the National Electrical and any local codes which may apply.
A main power disconnect switch capable of being locked only in the
OFF position should be used. Disconnect and lock out the power
before servicing the equipment, entering the bin, or resetting the
motor overloads.
The control panel MUST be mounted OUTSIDE the bin near the door. It
must be located so the operator has a full view of the equipment and can
see that all personnel are clear. It must NEVER be installed inside the
bin. The foot switch has to be plugged into the control panel and de-
pressed before the sweep is operational. It has a 10' cord so the sweep
can only be monitored from OUTSIDE the bin. The thermal protection
cord must also be plugged in before the sweep will operate.
