Outrigger Minimum Extension
The figure represents the condition "When the
crane is used with the outriggers extended at the
minimum" in the rated total load chart.
Fig. 4-122
NOTICE: Outrigger minimum extension is
defined as that:
1. The outrigger is set at the positioning pin
position (40° front, 30° back).
2. The inner box of all the outriggers is
minimised.
3. All the outriggers are placed on a level
surface.
4. Approx. 50mm is assured for clearance "a"
(between the outrigger bottom and crawler
bottom) in the figure.

NOTICE: If even a group of outriggers is
retracted to the minimum point, all the outriggers
are deemed to be extended at the minimum.
OUTRIGGER STOWING
WARNING!
• Do not let people approach toward the
machine when stowing the outriggers.
Staying around the machine may result in
serious accidents such as getting caught
between an outrigger and the main unit of
the machine.
• Verify that there is nothing under the rubber
tracks when stowing the outriggers.
If there is any object under the rubber
tracks, the machine may overturn and
serious accidents may occur when stowing
the outriggers.
• Stop the engine for operation except for
extending/setting the outrigger cylinders.
The third person touching an outrigger may
result in sudden movement of the outrigger
cylinder, which may lead to serious
accidents.
• When the position pin is removed, the
outrigger loses the support and rotates.
Always hold the outrigger with one hand
when removing the position pin.
• Do not put your hands or fingers around the
gaps of movable areas when stowing the
outriggers. Your hands or fingers may get
caught, and it may lead to serious
accidents.
• Insert the position pin to the end when
stowing the outriggers.
• When lowering the raised machine, operate
the eight outrigger switches so that the four
outriggers are lowered little by little.
Suddenly retracting two outriggers just on
the right side or left side will cause
instability in the machine and it can
overturn the machine.
• Do not perform the outrigger extending
operation after they are set on the ground.
Doing so applies unreasonable force on the
outriggers, resulting in the outrigger
breakage.
• Always set the travelling lock lever to the
"LOCK" position when operating the
outriggers.
