from our manufactures is designed to specific loading criteria using solid
rod or angle for all structural
members. owers are equipped with a
standard face mounted ladder with inside
corner mounting as an option.
Calculation contain the necessary data for
members, antennas and feeders. The wind forces on the tower are calculated
to assure the correct allowance ,twist and sway , orientation of members
and the incidence of antennas and feeders to the wind. Secondary members
(redundant) are checked as part of a sub-frame bracing the main member as
required by JIS,BS,DIN, TIS. and other codes. Bolted connections for towers
made of angle sections are checked and for other types of members they
can be checked against capacity limits. Foundation loads are calculated for
ultimate and service conditions. The towers shall
be square or triangle self supporting towers of trussed steel construction.
