Chapter 2: General Overview
Assembly
• Build one ring of sidewall and make sure to caulk all seams.
• Add top outside stiffeners and inside stiffeners at the same time to the rings of the sidewall sheets
NOTE: These top stiffeners are the lightest gauge stiffeners and will get heavier as the bin is raised.
Therefore, the heaviest stiffeners are located at the bottom of the bin and are installed last.
• Install the wind ring to help support the rings.
• Install the center collar tower support in the center of the bin.
• Install the eave brackets to the inside stiffeners.
• Install the eave angles to the sidewall sheets. (Note how these are aligned.)
• Install the tension member and/or compression channels to the eave brackets.
• Lift the pre-assembled A-frames, installing them in “opposite pairs” (across from one another) to
balance out the load as you install.
• Install the lower roof panels.
• Install the upper roof panels.
• Cut roof exhauster holes evenly spaced in upper panels.
• Install the roof flashing and peak cap.
Guidelines for Construction Procedures and Lifting Jack Usage
The following procedure is a guideline when using a lifting jack. Follow this general guideline when lifting
the bin as sidewall sheets are being installed.
NOTE: The roof and the top ring for odd ringed bins or the roof and 2 rings for even ringed bins, will be
installed prior to the beginning of bin lifting procedures. Refer to all other procedures on sidewall
and stiffener installation prior to the start of construction.
IMPORTANT: Begin building with the bin oriented for doors and material handling equipment to be in the
correct position when bin construction is complete.
1. Consider the starting location of the bin, relative to the location of the doors and other accessories.
Proper placement of lifting jacks in relationship to anchor bolts could make a difference in final
locations. Note that the sidewall sheets will be staggered.
2. The bin is lifted by the use of lifting jacks. Lifting jacks are used to slowly and evenly lift the bin
during construction. Lifting jacks must be properly sized and designed to carry all loads and job site
conditions associated with the construction of the bin.
• The number of lifting jacks required is best determined by personal experience and expertise.
Factors such as bin size, jack design, construction conditions, support surface, etc., are all to
be considered when deciding how many to use. If in doubt, use one jack on every sheet.
• The lifting jack must be adequate to carry all loads. Heavy duty jacks, generally hydraulic or
electric powered in the case of large bins, should be used for commercial installation. All jacks
should be secured with braces or otherwise maintained in a stable condition.
• Lifting of the bins should not be done under windy conditions.
• Follow the jack manufacturers recommendations on capacity and operations.
