CLAMSHELL - WEAR CHECK
When the normal wear of the clamshell blades and
end stroke stops exceeds the allowed value, the
clamshell cylinder may get damaged. In such a case
the allowed cylinder stroke is exceeded; cylinder
piston and liner bump one against the other at
stroke end.
To verify the wear status on clamshells for trenches,
reference marks are applied in the factory:
- on the guide rod (1) by means of a punch;
- on the cylinder rod (2) by means of a tool.
Repair the bucket prior that the cylinder rod (2)
aligns with one of the marks on the guide rod (1).
The lower mark indicates the clamshell blades wear,
while the upper mark indicates the wear of the end
stroke stops of the clamshell clams.
