In-Depth Information
pole that has not been plugged. If longitudinal cracks occur, the bolts
should be loosened until the crack closes. If the cracks do not close, the
Purchaser should notify the Manufacturer.
Tightening Through Bolts
Specifi c instructions should be supplied by the pole Manufacturer and
connection designer for tightening bolts. The construction crew should be
held responsible for the correct application of connection specifi cations.
Inserts
Ladder clips, step bolts, or other climbing devices, and groundwire
connections usually are attached to inserts cast into the pole. Care must
be used when making connections to inserts to avoid pulling the inserts
out of the pole.
Banding
Attachments can be made to concrete poles using stainless or galva-
nized steel bands. Bands should be of suffi cient strength to transfer the
load from the attachment to the concrete pole. Over-tightening of the band
is usually not a problem because of the inherent strength of the concrete
pole in compression (see Fig. 8-6).
