I believe what they are concerned about with lifting is use in a
elevator application. Many times people want to use these winches for a
people-lift application which can cause all kinds of problems if one
fails (lawsuits etc.). Maybe there is some other issue at work here,
but it seems to me the limiting factor in raising a tower section(s) is
not only its lifting capacity, but its ability to safely brake/lock once
the sections are in place at a given height.
