6.3.2 Switching on the boom floating position
If the main boom has been placed on a trailer, the boom floating position
must be switched on so that the main boom can move up and down.
• Enter the RCL code for the current rigging mode.
• Fully retract the main boom.
• Raise the main boom to a permitted angle within the working range.
• Turn the superstructure to the 0° to the rear working position and place the
main boom on a trailer.
• Remove the padlock (2).
• Switch over valve I – lever (1) horizontal and
pointing outward.
• Secure the lever (1) with the padlock (2).
• Switch the valve IV – lever (3) points down-
wards.
The boom floating position is now switched on.
H
Switching off the boom floating position; Ã p. 12 - 17.
G
Risk of accidents from the boom floating position being switched off!
Always switch on the boom floating position when the main boom is on
a trailer.
This prevents the full weight of the trailer briefly becoming suspended from
the main boom on uneven ground, the axle loads from rising suddenly,
or the truck crane from tipping when driving around corners.
G
Risk of accidents from the main boom dropping down!
You may only switch the boom to the floating position once the main boom
has already been set down on the trailer.
This prevents the raised main boom from dropping down.
