From time
to time, older tower silos collapse. Structural components can
be weakened by seepage and the corrosive effects of silage acids.
If damage is not repaired and routine maintenance is neglected,
silo collapse is a distinct possibility.
Seek professional advice concerning silo repairs if you suspect
that concrete deterioration has occurred.
Following is a checklist of silo components that need
to be assessed during a silo inspection:
- Wooden doors should be checked for rot and physical damage
- Check bolts and bolt heads for tightness and degree of
corrosion
- Evaluate corrosion and physical damage to door steps
and latches
- Cast iron hinge eyes should be tightened and assessed
for corrosion
- Concrete door frames should be checked for deterioration
and physical damage
Doors must seat properly in their
frames for latch systems to work effectively
- Replace wire rope on the unloader if signs of wear are
evident
Outside ladders should be fitted with structurally sound
safety cages to prevent falls
