Entering the RCL Code
Enter the RCL rigging code for the boom extension angle in
accordance with the current rigging mode of the crane, refer
to the Load Chart, Chapter Remarks.
When adjusting the angle without an auxiliary crane, you
must enter an RCL rigging code, refer to Entering the
Rigging Mode, page 3-81. The RCL rigging code depends
on:
• the rigged outrigger span
• the rigged counterweight
• the working position.
The superstructure must be in a working position permitted
by the Load Chart for the RCL rigging code that was entered.
Setting an Angle of 20° or 40°
This section assumes that the extension has been pinned in
front of the main boom and the unreeved cable has been laid
beside the extension.
1. Enter the RCL rigging code for the extension angle, refer
to Entering the Rigging Mode, page 3-81.
2. Extend the main boom as far as is permitted for the RCL
rigging code set, or as far as possible given the space
available.
3. Lower the main boom until the lattice extension head
touches the ground.
4. If the ground cannot be reached, you can incline the
crane further, refer to Inclining the Crane, page 4-39.
NOTE: In the steps which follow, the extension head is
pulled or pushed over the ground. Lay boards or
similar under the skids on the extension head so
that it is not damaged.
5. If necessary, relieve the load on the adjusting pin (1)
(Figure 4-57) by lowering the boom slightly.
6. Raise or lower the main boom so the pin (1) can be
inserted into the position for the angle required, refer to
Extension Angle Adjusting Mechanism, page 4-38.
7. Raise the main boom slowly until the extension head is
no longer touching the ground. The head of the
extension will be pulled across the ground.
8. The extension will then be inclined by the angle set.
9. If you inclined the crane using the outriggers in order to
set the angle, align it to the horizontal again.
10. Fully retract the main boom. While doing so, the lattice
extension must not touch the ground; raise the boom as
necessary.
11. Set down the head of the lattice extension on the
ground.
12. If you inclined the crane using the outriggers, align it to
the horizontal now so that the lattice extension sections
can be folded more easily.
Inclining the Crane
In order to set the angle of the adjustable extension, you
must set it down on the ground by extending and lowering
the main boom.
Depending on the space available, the condition of the
terrain or a limitation on the telescoping due to the current
rigging mode, it may be that the head of the extension cannot
be set on the ground by telescoping and lowering the main
boom.
In this case, you can use the outriggers to incline the crane.
1. Fully extend the rear outriggers and jack cylinders.
2. Fully extend the front outriggers.
3. Extend the front jack cylinders to raise the front wheels
off the ground.
CAUTION
Risk of Damage to the Wire Rope!
Unreeve the hook block and lay the hoist cable beside the
boom extension before you set the angle of the extension.
This prevents the cable from being damaged when the
head of the extension is set on the ground.
WARNING
Crushing Hazard!
If the extension is lowered onto timbers or some other
structure to set the angle, keep in mind that as the
extension is raised the extension head will slide towards
the crane until the set angle is reached.
The extension could slip off an unsuitable structure, fold
down and cause serous injury or death.
