Overview for a Typical Bin Installation
These are the typical steps one would perform when constructing a grain bin. Procedures may vary
depending on the different site requirements.
Pre-Assembly Activities
• Sorting and grouping parts
• Install vent to roof panels
• Assemble the rafter clips to rafters on the ground
• Install wind ring bracket to the stiffeners
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 two 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 loca-
tions. 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. Fac-
tors such as bin size, jack design, construction conditions, support surface, etc., are all to be consid-
ered 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.
3. Lifting brackets should be attached through the stiffener bolt holes. Normally you will need to attach
to at least four (4) bolts per stiffener.
4. Raise the bin just high enough to assemble the next ring. When lifting the bin,
all jacks must lift at
an equal rate
. Monitor the lift to ensure even lifting is occurring.
5. To the
inside
of the first ring, bolt the next ring. Be sure to
stagger
the sheets and select the proper
gauge material.
6. Lower the bin onto the foundation after assembling and tightening bolts on the new ring or rings.
7. Attach stiffeners to the body sheets every two (2) tiers (on the external surface of the bin). You may
want to leave sheets loose to make the attachment of the stiffeners easier.
