Guidelines for Installing a Sidedraw System
A sidedraw system will allow content unloading using gravity and is done from the inside of the bin.
Before You Begin
NOTE:
If a sidedraw system is to be installed, the standard 3/4" anchor bolts must be replaced with 1"
anchor bolts.
General Guidelines to Follow Before Installing a Sidedraw System:
• Side discharge is only permitted in stiffened bins when a GSI manufactured sidedraw flume system
has been installed. No corrugated steel bin must be unloaded through the sidewall without
installation of such a system and permission of the manufacturer.
• A sidedraw should not be the only discharge system available. A standard center discharge and
conveyor must be installed.
• Installation of multiple systems may require additional wind rings and must be placed a minimum of
90° apart. Installation of multiple systems requires approval of GSI.
• Sidedraw systems are intended for use with dry, flowable grain. Sidedraws are not to be used for
poorly flowing products. This is not unique to GSI bins and flume systems, but is a general rule for
such systems.
• In multiple system installations, only one sidedraw may be used at any one time.
• Filling must not be occurring at the same time as the grain is being discharged through the sidedraw
flume system.
• Prolonged storage of grain in the sloped condition produced by sidedraw discharge may accelerate
differential settlement and result in deformations of the bin. After using the sidedraw system, the
sloped grain must be returned to a near level condition by use of the center discharge. Leveling of
the grain should also allow more even consolidation of foundation and fill soils and produce more
even settlement of the bin.
• If past experience or geotechnical investigations indicate significant foundation level soil variations
or a site propensity toward differential settlement, sidedraw usage may be prohibited or severely
restricted. In this situation the use of a flume system should be reviewed with geotechnical
consultants or the foundation engineer.
• Before installing, determine if the bin design is a two post stiffener (48).
• Do not install a discharge chute on a vertical seam.
• A discharge chute should be installed at the standard height.
