4.5.6.3 Derricking mechanism
a) Components of derricking mechanism
Through changing the length of wire rope reeved between derricking pulley blocks
(includes derricking crown block and derricking traveling block), the derricking mechanism,
via derricking winch, can adjust boom angle so as to change the working radius. We can
use A-frame and boom frame to carry out derricking movement. During derricking, the
derricking crown block is located at the top of A-frame, while the derricking traveling block
is on the other end of anchoring rod, so the boom angle can be changed with the variation
in the length of wire rope between the derricking pulley blocks.
