automatic rotation system uses slewing bearing
system like excavator rotation system instead
of gear reducer type which often breaks
to prevent damage of flow control valve
rotation speed can be adjusted by adoption
of specially manufactured bearing. Deceleration
function is adopted in slewing bearing system.
check valve is adopted for safety to prevent
with large capacity cylinder for strong
Rotating Grapple Bucket can be attached
at mini to 40-ton class excavators of all
check valve installed in the cylinder: When
the cylinder receives excessive force, it
functions as a shock-absorbing function
to prevent twisting, crack at the welded
part and breakage of cylinder seal kit and
also to prevent slewing bearing clearance.
a special steel of POSCO, is adopted for
all models. Light weight and high elasticity
steel plates secure low abrasion and excellent
function in slewing bearing and cylinder:
Motor protection and shock prevention function.
