5.7.4.1 Components of SFV boom
SFV boom comprises main boom (S) and heavy fixed jib (FV). The main boom length varies
from 41 m to 77 m, and the heavy fixed jib length is 6 m. The heavy fixed jib can be assembled
in the angle of 14° or 20° to main boom. When different main boom length is required, the
operator only needs to disconnect main boom pivot section from main boom head, and then
install main boom intermediate sections between them. In this way, the main boom can be
assembled to required length.
Main boom sections in this boom configuration are pinned together in the same way as that in S
boom configuration.
