Automatically stops boom or luffing hoist from lowering and
load drums from hoisting if the load contacts a block-up limit
switch.
The load on corresponding drum can be lowered and boom
or luffing jib can be raised, if they are not at the maximum up
limit, after a block-up limit switch is contacted.
The appropriate limit bypass switch must be turned to the
bypass position before a load can be hoisted above the limit.
4. Luffing Jib Up Limit
Two luffing jib up limits stops are provided:
• JIB MAXIMUM UP 1 (max working angle): automatically
stops the luffing jib when the boom to jib angle is 168°
The appropriate limit bypass switch must be turned to
the bypass position to allow the jib to be raised an
additional 3° to JIB MAXIMUM UP 2 limit
• JIB MAXIMUM UP 2 (max angle): automatically stops
the luffing jib when the boom to jib angle is 171°
This limit cannot be bypassed for cranes meeting 2010
European requirements (CE). See Table 3-3
for
bypassable limit identification.
The luffing jib can be lowered after either limit is contacted.
NOTE: For current production cranes meeting 2010
European Requirements the luffing jib cannot be
lowered after JIB MAXIMUM UP 2 limit is contacted
until the limit switch is reset.
When the limit is contacted, operation
will stop and the jib up prompt (shown
to right) will appear on the main
display.
Once the prompt appears, release the
control handle to off and press the
confirm button (shown to right) to
reset the limit switch. The luffing jib
can then be lowered.
5. Luffing Jib Down Limit
Two luffing jib down limits stops are provided:
•JIB DOWN 1: turns on fault 50 alarm to alert operator
that jib is near maximum down limit 2 (occurs when
boom to jib angle is 60° regardless of jib type — layout or
fold-under)
• JIB MAXIMUM DOWN 2: automatically stops the luffing
jib when the boom to jib angle is:
- 57° for layout luffing jib
- 10° for fold-under luffing jib
This limit cannot be bypassed for cranes meeting
2010 European requirements (CE).
Non-CE machines can be bypassed if handle
returns to neutral while bypass is held.
The luffing jib can be raised after the limit is
contacted.
NOTE: For current production cranes meeting 2010
European Requirements the luffing jib cannot be
raised after JIB MAXIMUM DOWN 2 limit is
contacted until the limit switch is reset.
When the limit is contacted, operation
will stop and the jib down prompt
(shown to right) will appear on the
main display.
Once the prompt appears, release the
control handle to off and press the
confirm button (shown to right) to
reset the limit switch. The luffing jib
can then be raised.
WARNING
Falling Boom/Jib Hazard!
To prevent boom and luffing jib from being pulled over
backwards:
• Proceed slowly when operating above JIB MAXIMUM
UP 1 angle
• Do not raise luffing jib above JIB MAXIMUM UP 2
limit
WARNING
Falling Boom/Jib Hazard!
Do not lower luffing jib below maximum down limit 2.
Structural damage will result, possibly causing boom and
luffing jib to collapse.
