10. Lifting Jack
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 two (2) stiffener anchor bolts. The sidewall sheets are
also staggered 1/2 from end to end.
2. Lifting brackets should be attached through the stiffener bolt holes. Normally you will need to attach
to at least four (4) bolts per stiffener. 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 10A.)
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. You may want to leave sheets loose to make the attachment of
the stiffeners easier.
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.)
