Safety Tips For Jib Operation
1. The anti-two-block switch weight and cord must be
attached to the jib when deployed.
2. Do not lift load with the boom tip when the jib is pinned
on the boom tip.
3. Operate with jib by radius when main boom is fully
extended. If necessary, increase boom angle to maintain
loaded radius.
4. When radius is between points listed on capacity chart,
the load shown at the next longer radius shall be used.
5. Operate with jib by boom angle when main boom is not
fully extended. Do not exceed rated jib capacities at any
reduced boom lengths.
6. When angle is between points listed on capacity chart,
the load shown at next lower boom angle shall be used.
7. Ensure jib is stowed correctly.
8. Removal of swing around pins, C, without proper
installation of stow pin A and pin B, may allow jib to fall
off.
9. Extending boom with jib stowed and failure to remove
swing pin, C, will damage unit upon extension.
10. Attempt to only the swing jib to working or stowed
position when boom is horizontal, stow pin A and pin B,
are removed and swing pins, C, are in place. Jib could
swing uncontrollably if boom is not horizontal.
11. Crane shall be fully set-up according to proper set-up
procedures outlined previously when stowing or
unstowing jib.
12. Operate boom and turn functions very slowly and
carefully when using jib since jibs can increase boom
length by 50%.
13. Area where jib swings around must be clear of
obstructions and power lines when stowing and
unstowing jib.
14. Use safety glasses when pounding pins with hammer.
15. Do not extend/retract boom unless boom is horizontal
when stow pin A and pin B are removed during stowing
or unstowing procedures.
16. Always put spring clips in pins to ensure that they will
stay in place.
17. When the jib is stowed, the boom can not be fully
retracted if a boom tip attachment option is installed.
Also, on manually extendable jib options:
1. Extension retaining pin, E, must always be installed
when operating.
2. All swing around (stow and unstowing) operations shall
be done with jib retracted and pinned.
3. Extendable section may slide out of 1 st section jib when
pin, E, is removed. Keep personnel clear of area.
Side Folding-swing Around Jib Operation
NOTE:
When lowering the boom below horizontal, two
persons may be required. With the telescope
control in neutral, the boom may creep out when
below horizontal.
Deployment Procedure
1. Using boom telescope function, fully retract boom.
2. Using lift function, lower boom to allow for easier access
to jib deployment pins C1 and C2.
3. Install pins C1 in upper and lower jib ears. Install retainer
spring clips. These pins will be used as a pivot point to
swing jib into the deployed position.
4. Locate the stowed position of pins C2. If in jib
attachment holes or boom sheave case jib holes,
remove pins from storage location.
5. Remove t-handle Pin B from top ear of jib.
6. Remove stow Pin A from ramp/bracket assembly on jib
and stow in Stow Loop D and install spring clip.
7. Using lift function, raise boom to a horizontal position.
8. Attach tag line to sheave case end of jib.
9. Using telescope function, slowly extend boom
approximately one foot. This procedure will pull the jib
out of the stow bracket.
Use Caution during this step. The jib is free to swing
away from the boom upon boom extension.
CAUTION
•
Boom tip attachment can
contact jib in stowed position
when boom is fully retracted.
•
Contact can cause damage to
boom extension system and
jib stow system.
•
Boom must be left extended
.5 ft (.2 m) to prevent contact.
•
Boom attachment must be
removed for retracted boom
lifting operations.
