Operations with rubber crawler
chains
When using rubber crawlers, the following points
have to be observed:
– The rubber crawler chain must have the correct
tension. Incorrect crawler chain tension is
detrimental to travel performance and adds to the
wear of the crawler chain.
– Do not drive or turn over sharp edges or stairs
since the crawler chain is stressed only on special
points (21/A) and fissuring or cracking of the
rubber and the steel insert may occur.
– Prevent stones and other substances from getting
into the crawler chain as they may cause the
crawler chain to be extended or damaged.
– Do not undertake any sharp turns on surfaces with
a high friction resistance such as rough concrete.
– Avoid that the rubber crawler chain is
contaminated by fuel or oil and clean immediately
if this has occurred.
– When working on salt water beaches, the rubber
crawler chains must be thoroughly cleaned every
day using clean water. The steel insert in the
rubber crawler chains may be damaged due to
corrosion.
Attention
This crawler excavator can be equipped with
either steel or rubber crawler chains.
If the excavator is equipped with rubber
crawler chains, work on paved roads, within
buildings, etc. can be performed without
damaging the road ways.
