The Counterweight submenu opens.
Extending/Retracting the lifting cylinders
This section describes how to operate the lifting cylinders
manually,
- for correcting the displayed rigging mode and
- for pre-charging the counterweight afterwards.
NOTE: Always lift and lower the counterweight in
automatic mode, otherwise swing with extended
lifting cylinders will be blocked.
Pre-charge
Use the UP arrows to fully raise the cylinders. This is needed
if the cylinders were operated manually and not fully raised.
or
The accumulator will charge automatically if the pressure is
low, the engine is on, and no other function is using the
valves.
Automatic mode, rigging
While the automatic process is being performed, you can
always
- cancel the automatic process.
- interrupt the automatic process by letting go of the
control lever. After moving the lever in the displayed
direction once more, the automatic process is
continued.
Rotating with the rigged counterweight
The following table shows, depending on counterweight and
outrigger span, whether rotating the superstructure is
permitted or whether the superstructure must be locked after
rigging the counterweight.
WARNING
Tip-over Hazard!
You may only rotate the superstructure with rigged
counterweight if the truck crane is stabilized with a
sufficient outrigger span. If this minimum outrigger span is
not observed, the truck crane can overturn during rotating.
For small counterweights, the main boom must be raised
to one of the angles permitted in the operating area. With
larger working radius, the truck crane can overturn during
rotating.
