Crawler type and application
Choosing the track shoe meet the operating requirements.
According to the floatability and grounding pressure to choose the width of the track shoe, choosing the
narrowest track shoe possibly. If the used track shoe is wider than needed, it will increase the load of the
track shoe, and lead the track bend, link broken pin-axis broken, loosen of the track shoe and other kinds of
problems.

Application type
Heavy load digging: digging or loading mountain gravel, explosion stone, hard clay, soft stone and so
on.
Common digging: digging or loading sand, gravel, clay and common earth.
Light load digging: digging or loading dry and incompact earth, sand, mud and so on. Their volume
density is required below 1600kg/m3.
Importance： using the improper bucket may lead serious damage of the boom, arm,
hydraulic cylinders and other working device elements.
z
For digging or loading hard soil or stone, suggested to use the rock bucket with high intensity and
high degree anti-wear ability。

Fig. 1-2 Drawing of hammer-style knapper
The operator must choose proper hammer-style knapper for the equipment.
Before installing the knapper onto scoop lever, please read carefully this book and operational manual of
hammer-style knapper and verify or check it according to the requirement. The installment of knapper tubing
should refer to the above picture.
Important: when connecting tubes of hammer-style knapper, pay more attention to: 1)
while changing the bucket or scoop into knapper, don’t let the dirt enter hydraulic
system.2) when the knapper is not in use, lid should be placed on the tube inlet on the top
of scoop lever and the plug should be put on the hose end of the knapper to prevent the
dirts into the system. While standby lid and plug must be contained in toolkit for the
convenience of usage.3) after the connection, check the sealing of connection to see if there
is any oil leakage or flexibility of pipe connectors.

Weight of hammer-style knapper
a)
When the components other than the standard bucket is installed on the machine, the stability of
machine may change, for the heavy parts will not only affect the controlling ability, but also reduce
the stability of the machine, leading to the problem of safety possibly.
r
Operating and Maintenance Manual 151
b)
Before installing hydraulic hammer-style knapper, make sure to take the controlling ability of the
knapper into consideration and refer to the following list to choose hammer-style knapper.

c)
When choosing the hammer-style knapper, weight is not the only considered factor, instead,
“SPECIFICATION LIST OF HAMMER-STYLE KNAPPER” should be referred to choose the best.
d)
Hammer-style knapper with too big installment length should be avoided, which may lead to the
damage on the knapper.
e)
While putting on the knapper with the max. weight listed above make sure to stand in the front or at
the rear of the machine, meanwhile try your best not to work at the max. working radius of the
machine.

Specification of hammer-style knapper
The following list shows some hammer-style knapper, which can be fixed on Xugong excavator.
Before the adoption, please inquire the dealer of hammer-style knapper in earnest.
When using the parts other than the standard bucket, the load on machine body normally is bigger
than that with the bucket in use. If the operation is unsuited, it will damage the parts even the machine
body. So please read all this book to prevent the happening of such accident.
