Anchor Tank Before Second Ring Assembly
Anchor all jacks securely with metal stakes and cables (use one jack per sidewall sheet). Now raise the
tank just enough to assemble the next ring. When lifting the tank crank all jacks at an equal rate. This will
prevent bowing previously assembled rings and make for easier hole alignment. To the inside of the first
ring bolt the next ring. Be sure to stagger the sheets and select the proper gauge material. Lower the tank
on the foundation after assembling and tightening bolts on each new ring. Now re-bolt lifting straps to the
lowest ring in place thus far.
NOTE:
Add outside ladders and other accessories to tank walls as you continue to raise the tank.
After body sheets are assembled and bolts are tightened, raise the tank and attach the legs. Do not put a
bolt in the bottom sidewall hole yet, because the hopper must be attached here. When the legs are in place
and tightened, release the jack enough to rest the tank on the legs.
