is by attaching the choker below a solid piece of pole hardware. A step bolt
or ladder clip should not be used to lift the pole to a vertical position.
Structure Considerations
Concrete pole construction utilizes single pole, multipole, H-frame,
and hybrid pole construction. A hybrid structure consists of a concrete
base section with the remainder of the structure being tubular steel.
Because of the weight of concrete poles, each pole in a structure is usually
set separately. For braced structures, such as X-braced H-frames, the
bracing is usually attached after each pole has been individually set. This
requires close attention during erection to establish proper setting eleva-
tions and pole-to-pole spacing. The Manufacturer can provide extra holes
and special attachment mechanisms that allow for greater fl exibility in
fi tting bracing to installed poles.
