f) Insert pin spindle to connect the inner pipe and outer pipe of rear tilting-back support of
fixed jib, and then secure it with cotter pin. There are many pin holes on the outer pipe and
the rules to choose which pin holes should be put into the pin spindle are: take the position
of the inner pipe of rear tilting-back support(G75) as the benchmark when the inner pipe of
front tilting-back support (G74) just support the spring. Put the pin into the hole nearest to
rear tilting-back support (G75), which is shown in the figure 5-67.
g) Push left control lever forwards to unwind the hoisting rope from the hoisting winch 2, and
then pull the rope forwards to the rope pulley at the fixed jib head through the rope pulley
on the FA-frame, and reserve a certain length of rope for reeving load hook.
h) Move right control lever to the left to wind derricking rope, then the main boom will be
raised, and the fixed jib is lifted off the ground a little higher than the hook. Put a 6t load
hook under the fixed jib head, connect the wire rope of hoisting winch 2 and load hook with
rope lock.
i) Continue to wind the derricking rope to raise main boom, and meanwhile unwind the wire
rope of hoisting winch 2 to keep the hook on the ground.
When main boom is raised to 30° position, wind the wire rope of hoisting winch 2 to lift the
hook.
Continue to operate right control lever to left to spool up derricking winch until main boom
is raised to the required position, then stop raising.
