Tower base
Suspend the ‘U’ bolts centrally in the hole in the correct position and orientation. This can be
achieved using a suitable piece of wood which will span the hole, drill four holes Ø12 using the tower
base as a guide, insert the 2 base foundation ‘U’ bolts through the holes and fit the 4 nuts ensuring
that approx 30mm of thread protrudes above the concrete
Fig 3a. Foundation bolt spacing is 131 x 113mm.
Check for correct spacing of the foundation bolts by positioning tower base brackets on the
protruding threads and laying tower tube between the brackets prior to mixing concrete.
