Lifting Jack Usage
General Lifting Jack Instructions
1. Before constructing the bin, consider the location of the door and other accessories. Proper
placement of lifting jacks in relationship to anchor bolts could make a difference on odd or even ring
bins. Walk-through door is centered between two stiffener anchor bolts. The sidewall sheets are also
staggered 1/3 from end to end.
2. Anchor all jacks securely with metal stakes and cable.
3. Raise the bin just high enough to assemble the next ring. When lifting the bin, crank all jacks
equally. This will prevent bowing the previously assembled rings and make for easier hole
alignment.
(See Figure 6E.)

4. Bolt the next ring to the inside of the first ring. Be sure to stagger the sheets and select the proper
gauge material.
5. Lower the bin onto the foundation after assembling and tightening bolts on the new ring or rings.
6. Re-bolt the lifting straps to the lowest ring in place thus far. Continue ring additions until ready for the
door installation.
NOTE: The number of lifting jacks required is best determined by personal experience. Factors such as
bin size, soil compaction, wind velocity, jack design, etc., are all to be considered when deciding
how many to use. If in doubt, use one jack on every vertical seam. Be sure to use heavy duty jacks
for commercial installation.
NOTE: Add inside and outside ladders to bin walls as you continue to raise the bin. (Refer to the manual
supplied with the ladder.)
