M A E D A Mini-Crawler Crane Section 4 – OUTRIGGER SETTING
9/2020 MC285CB-3 4-47
Setting Outriggers (Multi
Outrigger State)
WARNING! The situation in which at least
one of the four outriggers is extended
differently is referred to as multi outrigger
state.
Multi outrigger state offers advantages in
locations where space is limited. Make sure you
understand the particular characteristics before
using this function. The function affects crane
stability. Additionally, restrictions apply to the
range of motion, and the rated total load will also
change.
For more information the multi outrigger state
characteristics, see “Crane Operation Prohibited
Zones Due to Outrigger Rotary Angle” on page
4-50.
For multi outrigger state, rotate the outrigger
rotary (3) and insert the position pin (4) at a
position where the “Standard” label on the side
of the rotary does not align with the “Standard”
label on the side of the frame, giving an
extension angle other than the standard angle
outrigger state.
Even when all four outriggers are extended at
the standard angles, the situation in which the
Outrigger Angle Setting Lights are not all lit in
green or yellow is referred to as Multi outrigger
state.

NOTICE: For more information on operations
other than the outrigger rotary positions, see
“Setting Outriggers (Normal Outrigger State)” on
page 4-44. The crane will not operate if two or
more adjacent “Outrigger Angle Setting Lights”
are lit in green.
• At least two of the adjacent outriggers must
always be set at the standard angle, and must
be set to "MAX" extension.
Slewing restrictions always apply when crane
is in Multi-Angle outrigger state, which means
one or two adjacent outriggers are set at Multi
angle position.
• Slewing by 360 degrees is allowed when all
four outriggers are set at the standard angle.

If the Outrigger Angle Setting Lights are not all
illuminated green or yellow, the system
automatically switches to “M: Multi Outrigger
State”
If “M: Multi Outrigger State” is flashing, the
above outrigger angle state are not satisfied and
the outriggers must be redeployed.
