999 LUFFING JIB OPERATOR MANUAL SETUP AND INSTALLATION
Raising Boom and Jib (continued)
7. Slowly raise boom — do not raise luffing jib — until
fixed jib is hanging from backstay pendants with roller
just lightly touching ground.
Take care not to allow jib pendants to get caught on
side of fixed jib. Guide jib pendants clear of jib sections
as fixed jib rises.
8. Make sure jib stop pins are engaged. A personnel hoist
is required for this step:
a. Visually inspect that both jib stop pins are fully
engaged (Figure 4-25
, View F).
b. If not already done, install pins (4, Figure 4-25
, View
F) to anchor links (5) to luffing jib top.
9. Install weight ball or load block as shown in Figure 4-26
