[10] LEVELLING INSTRUMENT
If crane operation is performed with the machine tilted, tipping may occur.
Search for a place, while looking at the levelling instrument, where the machine body is
in a level state before starting crane operation.
If work is unavoidably performed on a slope, place planking or lay earth on the ground
to make the ground level.
This displays the inclination status of the machine.
The inclination and direction of the machine can be
determined from the position of the air bubbles.
Use this to check whether the machine body stopped on the
worksite is in a level condition.
