Rock Breaker Hammer Hydraulic Breaker Hammer For Excavator CAT liebherr KOBELCO
The hydraulic breaker hammer, also known as the rock breaker hammer, is one of the accessories often for excavators. It is common breaking equipment in mountain openings, pavement crushing, house demolition, mine crushing stones, and other working conditions. The construction efficiency of the hydraulic breaker is 2 to 5 times that of the ordinary breaker. The excavator hammer attachment can crush hard materials quickly and precisely, improving work efficiency and reducing manpower and time costs. In addition, We also provides demolition equipment such as pile breakers, diamond wire saws, concrete wall saws, and rock splitters.
The Application Scope Of Rock Breaker Hammer
The rock breaker hammer is an important excavator tool, and it has
many applications. Excavator hammer attachment is often seen in
mining, metallurgy, tunneling, road maintenance, municipal gardens,
demolition of old buildings, broken reinforced concrete, etc.
Hydraulic Breaker Hammer Working Principle
Install a hydraulic system inside the hydraulic breaker hammer, and
achieve the breaking effect by controlling the pressure of the
hydraulic system. The power source of the hydraulic breaker is the
pressure provided by the excavator, loader, or pump station. The
kinetic energy of the hydraulic oil inlet + kinetic energy of the
upper accumulator pushes the cylinder rod upward to compress the
nitrogen chamber. After pushing to the highest point, the reversing
valve switches direction.
High Efficient Excavator Hammer Attachment
The crushing speed of the excavator hammer attachment is related to
the speed of the hydraulic motor, and the speed of the motor is
related to the flow provided by the excavator. The hydraulic flow
determines the speed of the motor, and the hydraulic pressure
determines the torque of the motor. Under certain pressure, the
greater the hydraulic flow, and the faster the speed, the greater
the impact force generated by the hammer. The rock breaker hammer
not only hits a point, but widens the target’s crack, and damages
the surrounding soil and rock secondarily. Therefore, the
efficiency of this equipment is much higher than that of
traditional breaking hammers.
Product Advantages Of Hydraulic Breaker Hammer
A variety of specifications to choose from. Dopro provides various
specifications of hydraulic breakers for excavators, suitable for
different excavator models.
High durability. The oil return channel is designed on the pressed
surface of the oil seal to reduce the pressure of the oil seal and
improve the service life of the oil seal.
The design is reasonable. The power source of the excavator hammer
attachment is the hydraulic oil provided by the pump station of the
excavator or loader.
Widely used. The hydraulic breaker hammer is for the breaking of
collapsed concrete, walls, reinforced concrete, and other obstacles
and collapsed objects during earthquakes and firefighting
operations.
Impact crushing, no harmful gas emission; low working noise, long
working life of internal parts.
High crushing efficiency. The hydraulic rock breaker hammer has a
very large impact force, which can quickly break hard materials and
improve work efficiency.
High-crushing precision. The crushing hammer head of the hydraulic
breaker can be precisely controlled, and it can perform precise
crushing without damaging the surrounding structure.
