[3] OUTRIGGER MEDIUM EXTENSION
• Always place all outriggers securely before operating the crane.
If not all of the outrigger monitor lamps are illuminates (except for the boom stowing
lamp), The interlock system will be activated and, as a result, no crane operation can
be performed.
• Outriggers should be set to the ground while watching leveling instrument so that the
machine is set horizontally.
Tilting the machine more than 3° activates alarm buzzer. To stop the buzzer, place the
machine horizontally.
• Unless outriggers are extended to medium, work should be performed in accordance
with values shown in the “Use with outriggers extended to medium” column or “Use
with outriggers extended to minimum” column of the Rated Total Load Chart.
Working under improper values may cause the
machine to tip over. Be very careful.
• Even with all the outriggers extended to medium,
the outrigger width is decreased on uneven terrain
etc. even if the dimension “a” in the figure on the
right is 50 mm. In such a case, work should be
performed in accordance with values shown in the
“Use with outriggers extended to minimum”
column of the Rated Total Load Chart.
• Slewing 360° with a load lifted may expose the
machine to an unstable position. Even if the total
combined weight is within the rated total load,
reduce the working radius and traveling speed as
much as possible, and use sufficient care.
“Outriggers extended to medium” in Rated Total Load
Chart represents the condition in the figure on the right.
NOTES
“Outriggers extended to medium” means that,
(1) The outrigger set up angle is set to the position pin
position (40° front and 30° rear).
(2) Inner boxes on one of the outriggers are pulled out
medium.
(3) All the outriggers are placed on level ground.
(4) Dimension
a (distance between bottom of the
outrigger and bottom of the track) in the figure on the
right is approximately 50 mm.
The above represents “Outriggers extended to medium”.
NOTES
For N mode: Even if a single outrigger is extended to
“medium” from the position where all the outriggers are
placed at the maximum extended position, the condition is
defined as “outriggers extended to medium”.
For outrigger mode M and P see
