Excavator operators usually work out in the
field or construction sites; therefore, cautious investigation on the worksites
is crucial to the safety of the excavator operator and to the safe operation. First
of all, the operator should check the terrain and ground condition and use the
safest operating method, try to avoid traveling or operating the excavator in
areas with risk of landslide or falling stones, near cliffs, road shoulders or
trenches, because the soft and loosen ground in these areas may not bear the
excavator’s weight and vibration, as a result, the machine might sink or tumble
down. The ground may become softer after heavy rain, explosion or earthquake. If
the excavator has to work on a dam or near a ditch, vibration and machine
weight may trigger a landslide, thus protective measures have to be taken prior
to operation in order to prevent the excavator from tumbling down or falling
over. For instance, to solidify the ground, keep a safe distance away from the
ditch and assign a signal man when necessary.
If there are underground water mains, gas
lines, cables or high voltage electric wires on the worksite, the large excavator operator must inform and ask related utilities providers to mark the area, and
be careful not to cut any lines while digging the ground. When necessary, in
order to prevent any unauthorized personnel from entering the construction
site, it’s necessary to assign a signal man for the excavator operator and
build a fence when operating on a highway. In addition, the operator must be
extremely alert when operating on frozen ground as the excavator operation will
cause the ambient temperature increase, which may result in soft and slippery
ground. When traveling or operating the excavator in shallow water or soft
ground, the operator has to check the type and condition of rock bed as well as
the depth and water flow in advance.
