SILOS: CONSTRUCTION AND SERVICE 



takes made in caring for the silo is to neglect to loosen 

 the hoops when the staves swell after the silo has been filled. 

 This should be attended to; as soon as the silo tightens up the 



hoops should be let out 

 to the same point where 

 they were when they were 

 originally erected. The 

 paint on the ends of the 

 rods will indicate this 

 point, or it may be 

 marked by means of a 

 punch. If this is not 

 done the door-jambs will 

 be crushed together, the 

 edges of the staves 

 crushed, and the lugs 

 broken or at least bent 

 seriously. It requires only 



a few years of neglect in this way to use all the threads on the 

 hoops. Then the silo can not be further tightened without 

 washers or short pieces of gas pipe under the nuts.
