PLACE CRANE ON LEVEL AND HARD SOIL
• Always place the outriggers on a level, stable and solid
ground.
Attempt to operate the crane without outriggers firmly
contacting the ground may cause the Machine to trip.
• Always place all outriggers before operating the crane.
• Do not set any outrigger near an unsteady location such as
soft ground, verge or drilled hole.
In case the outriggers need to be placed on soft ground for
an unavoidable reason, always reinforce the ground by
laying a sufficiently large and strong base plate below each
outrigger supports.
CHECK OUTRIGGER PLACEMENT CONDITION
Always observe the following to prevent serious injuries and
accidental death when placing the outriggers.
• When placing the outriggers, always keep the Machine
sternly level while looking at the level gauge. Occasionally
check the level gauge and make sure to keep the Machine
level during the crane operation as well.
• Always place the outriggers at its “maximum extension”.
If, due to unavoidable reasons, you need to place the
outriggers without extending them to its maximum
extension, be sure to perform the work in accordance with
values shown in the “Outriggers extended to halfway”
column or “Outriggers extended to minimum” column of the
Rated Total Load Chart.
• Place the outriggers so that the crawler is approximately 50
mm above the ground.
• Make sure all of the outrigger position pins are securely
fixed.
