Boom Extensions
When operating the crane with a boom extension installed,
the maximum speed for the different power units is limited to
70%.
Setting the RCL
When a boom extension is installed the associated displays
change to include its graphical representation.
NOTE: If a hook block is reeved on the main boom during
operation with a boom extension, the loads given in
the Load Chart decrease and the RCL
subsequently switches off earlier.
The values which must be deducted from the load
capacities depend on the length of the boom
extension and the weight of the hook block. You will
find a table with the values in the Load Chart in the
section; Information on working with the swing-
away boom extension.
Enter the following into the RCL when a luffing boom
extension is installed, refer to Entering the Rigging Mode,
page 3-81:
• hydraulic jib’s length
• mechanical jib’s length and the angle the jib is set at
• the actual rigging configuration;
- using the corresponding RCL code according to the
Load Chart
or
- using the individual components
• the current reeving.
After entering the above information into the RCL, check that
the following displayed values correspond with the actual
rigging configuration of the crane (Figure 3-189) in the
Monitoring submenu, RCL Monitoring Submenu, page 3-86:
3. On the RCL Monitoring
submenu, check whether
lamp II is on.
If lamp II is flashing,
switch the display to
lamp II, refer to Verify
Hoists Display, page 3-
123.
4. Check that the actual
reeving of the auxiliary
hoist (1) is displayed
correctly. Correct the
reeving if necessary,
refer to Verify Reeving,
page 3-124.
CAUTION
Do not change the hoist speed range with the hoist
rotating.

WARNING!
Equipment Damage Hazard!
During operation with the 36ft (11m) boom extension set
at 0° angle at the steepest boom position, the head
sheaves of the main boom can be damaged when a hook
block is raised or lowered.
Reduce the hoist speed so that the hook block is raised
slowly passed the head sheaves.
