Hydraulic breaker hammer
1. Guidelines for the use of hydraulic breaker hammer
Hydraulic breaker hammer is the most common work accessory. It is widely used in the
demolition of buildings, road cracking, tunnel operations, steel slag crushing, stones, and
crushing operations in quarries.
1) During crushing operations, please
make sure that the direction of the apex of
the hammer drill rod is perpendicular to
the surface of the broken object, and
keep it as long as possible. If it is inclined
to the surface of the broken object, the
drill rod may slip off the surface, which
may damage the drill rod and affect the
piston.
During crushing, please select the
appropriate hitting point, and confirm that
the drill rod is indeed stable before hitting.
It is required to keep adjusting the bucket
cylinder during operation to keep the
penetration direction of the drill rod and
the direction of the breaker hammer body
in a straight line.
2) During impacting, press the drill rod
onto the impact surface to make the
chassis is about 5 cm off the ground, and
the machine shall not be away from the
ground too much.
3) During continuous impacting to the
same impact surface, if the drill rod
cannot penetrate or break the surface
within 1 minute, change the impact
position to break it near the edge.
The direction of the apex of the hammer drill rod shall be
perpendicular to the surface of the broken object
