JIB OPERATION SAFETY
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.
When radius is between points listed on load chart, the
load shown at the next longer radius shall be used.
4. Operate with jib by boom angle when main boom is not
fully extended. Do not exceed rated jib capacities at any
reduced boom lengths.
When angle is between points listed on load chart, the
load shown at next lower boom angle shall be used.
5. Ensure Jib is stowed correctly.
a. Removal of swing around pins, C, without proper
installation of stow pin A and jib swing pin B, may
allow jib to fall off.
b. Extending boom with jib stowed and failure to
remove swing pins, C, will damage unit upon
extension.
6. Only attempt to swing jib to working or stowed position
when boom is horizontal, stow pin A and jib swing pin B,
are removed and swing pins, C, are in place. Jib could
swing uncontrollably if boom is not horizontal.
7. Crane shall be fully set up according to proper set-up
procedures outlined previously when stowing or
unstowing jib.
8. Operate boom and turn functions very slowly and
carefully when using jib since jibs can increase boom
length by 50%.
9. Area where jib swings around must be clear of
obstructions and power lines when stowing and
unstowing jib.
10. Use safety glasses when necessary.
11. Do not extend/retract boom unless boom is horizontal
when stow pin A and jib swing pin B are removed during
stowing or unstowing procedures.
12. Always put spring clips in pins to ensure that they will
stay in place.
13. When the jib is stowed, the boom cannot be fully
retracted if a boom tip attachment option is installed.
Manually Extendable Jib:
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. The extendable section may slide out of 1
st
section jib to
the mechanical stop when pin E is removed. Keep
personnel clear of area.
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 0.5 ft (0.2 m) to prevent
contact.
• Boom attachment must be removed for retracted
boom lifting operations.
