3.14 WORKING INSTRUCTIONS
3.14.1 STABILITY OF THE SHOVEL
WARNING
Before beginning work prepare a suitable Shovel base, to
ensure adequate stability for safe working of the Shovel.
The stability of the Shovel is determined according to DIN 24087,
and is based on a level ground.
The Shovel must therefore be operated in such away, that its sta-
bility is always ensured and the danger of tipping over is avoided.
When slewing the superstructure take in account, that the stability
of the Shovel is being reduced when the superstructure (bucket)
is turning in a transverse direction to the undercarriage.
Avoid working with the crawler tracks across the slope, as this
reduces stability and increases the tendency for the Shovel to
slide or to tip over.
In the following a few Examples of Operating and Working Condi-
tions which can reduce the Stability of the Shovel:
Overloading of the Shovel (Bucket overfilled).
Ground conditions such as loose sand or wet soil (possibility
of a cave-in).
Jerky acceleration or deceleration of working- and travel
motions.
Operating on a slope.
3.14.2 SHOVEL OPERATION
When working with the loader attachment, switch-off the fast
speed range (if equipped).
Do not operate control levers jerkily.
Do not work below overhanging rocks or earth masses.
Always keep a safe distance to the edge of an excavation
where bank cave-ins are possible.
Operation on a grade requires special care. Plan your work
so that the Shovel travels uphill and downhill parallel to the
grade. Bear in mind, that the Shovel’s stability is reduced
when operating on a slope.
Always keep the Shovel under control.
Know the Shovel’s limits - and do not exceed them.
