– When working underwater, do not tilt for more than 15° to
avoid immerge parts of the engine and damaging the radiator
fan or other electric
components.
– Take extra care if the riverbed is rugged or the stream is fast.
– The foundation of the working zone should be hard enough
to prevent the machine from sinking.
– Do not immerge the machine completely into the water: keep
the upper track shoe (that is on the opposite side of your
driving direction) out of it as a reference to prevent electric
shortcuts and inevitable injuries.
– When working on loose and rugged surfaces, the machine
may sink.
– Always check the position of the machine and observe the
crawler’s working conditions.
– Also, check the riverbed’s surface. If needed, readjust the the
machine’s position.
– Prevent water, slurry or sand from entering any of the center
swing adapter, the swing bearing or the gearing.
– In case that water or slurry has entered the swing bearing
or center swing adapter, stop working and move the machine
to a firm and dry ground.
– Resume work after corresponding observations and
necessary maintenance have been finished.
Risks when working on surfaces with poor bearing capacity
Warning!
– Avoid travelling on the surfaces with poor bearing capacity as possible
as you can.
– Crawlers should have full contact to the ground and not sink into too
deeply into the earth, so that the machine can still be towed out.
– In case of travel difficulty, lower the bucket to ground, retract the front
device, then pull out the machine using hoists.
– If slurry, sand or stones enter the crawler and prevent the machine from
moving on, do as follows:
o
Lift one of the crawlers off the ground using the front device
o
Rotate the other crawler forward and backward (see sketch)
to remove the foreign materials.
– If the machine suddenly stops while on favourable soil, tow the machine
using ropes. (Refer to section 5.5.6: “Towing” for more information).
NOTE: When jacking up the excavator using the front equipment, prevent
the machine from tilting.
