CRANE (continued)
7.
To unstow the crane:
a.
BOOM DOWN the second boom section (71) until it is clear of the boom rest.
b.
BOOM UP the first boom section (72) to a near-vertical position.
c.
BOOM UP the second boom section (73) to the desired working position.
8.
To lift a load:
a.
Manipulate the crane controls until the hook is over the center of the load.
b.
During all lifting operations, the first boom section must remain above horizontal (74). Lifting with the first boom
section below horizontal (75) greatly reduces the crane's lifting power and should be avoided whenever possible.
c.
At no time should the crane be used to lift a load when the second boom is in the "negative" position (76). The
second boom should only be used to lift loads when in the "positive" position (77).
d.
Attach the crane hook to the load's lifting eye or lifting rigging.
e.
Lift the load, avoiding sudden, jerky movements.
f.
Manipulate the crane controls until the load reaches the desired location.
