Lifting Jack Usage
General Lifting Jack Instructions
1. Give some thought before starting the bin, to the location of 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 2 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. Now raise the bin just high enough to assemble the next ring. When lifting the bin, crank all jacks at
an equal rate. This will prevent bowing previously assembled rings and make for easier hole
alignment.
(See Figure 6E.)

4. To the inside of the first ring, bolt the next 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. Now re-bolt the lifting straps to the lowest ring in place thus far. Continue ring additions until you are
ready for 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 manual
supplied with the ladder.)
