I recently asked a question about HDBX 48 torque loading. Another
towertalkian told me his failed in about 80 MPH winds. He sent me a
picture of his failed HDBX 48 (more heavily loaded than mine by a fair
bit) that failed. Something I noticed in the picture was that his
HDBX48?? had only *five* X-braces per section; I thought it looked odd,
so I went out and looked at mine: mine has *six* X-braces per section.
He said his was manufactured sometime around 1968-1970 while mine was
put up around 1986, so was probably made around that time.
Did Rohn change the design of their BX towers to add another X-brace to
each section, or am I seeing things?
