6.6.9 Crane movements during installation and removal
When the rear supporting box is removed, the setting down and raising of
the main boom and the slewing of the superstructure is monitored by RCL.
There are RCL codes for different working positions for an outrigger span of
7.98 x 8.50/1.00 m (26.1 x 27.9/3.3 ft).
Prerequisites The following prerequisites must be met:
– The auxiliary hoist must be removed.
– The counterweight is completely unrigged.
– The truck crane is rigged with an outrigger span of 7.98 x 8.50/1.00 m
(26.1 x 27.9/3.3 ft);
à p. 6 - 71.
– The truck crane must be level.
– All telescopic sections are retracted and locked.
Before installation
• Enter the RCL code for an outrigger span of 7.98 x 8.50/1.00 m
(26.1 x 27.9/3.3 ft) for the current main boom position (code for
0° position to the rear or 180° position to the front).
• Raise the main boom.
• Enter the RCL code for the outrigger span of 7.98 x 8.50/1.00 m
(26.1 x 27.9/3.3 ft) for the 360° slewing range.
• Rotate the superstructure into the position for mounting the rear support.
• Enter the RCL code for the outrigger span of 7.98 x 8.50/1.00 m
(26.1 x 27.9/3.3 ft) for the limited slewing range of ±20° to the rear.
After the removal
• Enter the RCL code for the outrigger span of 7.98 x 8.50/1.00 m
(26.1 x 27.9/3.3 ft) for the 360° slewing range.
• Slew the superstructure into the position for setting down the main boom
(0° to the rear, 180° to the front or ±15° to the rear).
• Enter the RCL code for the outrigger span of 7.98 x 8.50/1.00 m
(26.1 x 27.9/3.3 ft) for the current main boom position.
• Set down the main boom on the boom rest or on a trailer.
G
Risk of overturning when slewing the superstructure!
Always support the truck crane with an span of 7.98 x 8.50/1,00 m
(26.1 x 27.9/3.3 ft) (with auxiliary supports at the rear) and set the
corresponding RCL code before slewing the superstructure.
Do not override the RCL if slewing is switched off.
