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).
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.
The following prerequisites must be met:
– The auxiliary hoist must be removed.
– The counterweight is completely unrigged.
