Safety Information – [cont’d]
Operational Safety Program
The safe and efficient use of the Allied equipment
depends upon proper installation, operation,
maintenance and repair. Operational safety programs
must encompass all of these elements.
Accident prevention through operational safety
programs are most effective when the equipment
owner further develops the program by taking into
account his own experience in using and maintaining
equipment.
Developing such programs will help minimize
equipment downtime, while maximizing service life
and performance. Most importantly, it will minimize
the risk of personal injuries.
Personal Protective Equipment (PPE)
Personnel operating or nearby the equipment and
exposed to the hazard of falling, flying and splashing
objects, or exposed to harmful dusts, fumes, mists,
vapors, or gases shall use the particular personal
protection equipment (PPE) necessary to protect
them from the hazard. Such PPE may include safety
eyewear, face shield, hearing protection, safety
footwear, gloves, and dust mask. Supervisors shall
review proper PPE selection and ensure PPE is
made available to personnel. Personnel are
responsible for wearing PPE as directed by the
supervisor.
Protective Equipment - Guarding
Allied equipment designed with guards shall have
guards in place when equipment is in use. Guards
are fitted to the equipment to protect against unsafe
situations that could not be eliminated through design
measures. Where it was not possible to prevent an
unsafe situation by means of a guard, safety
messages appear on the equipment, warning
personnel of a hazardous condition.
Guards shall not be removed unless for the purpose
of inspection and service of components. All guards
must be reinstalled after service or adjustments are
completed. Do not operate the Allied equipment
without guards installed.
Additional guarding, not included with the Allied
equipment, is necessary at the operator’s station to
protect the operator and other nearby personnel
against flying debris from material being cut or
demolished. Do not handle, demolish or cut material
overhead without proper guards installed.
To prevent accidental start up, the control switch
shall be located in a protected area that is guarded
and makes it difficult to accidently operate the
equipment.
Unapproved Modifications
In order to provide and maintain efficient production
and reliable service, while ensuring operator safety,
the Allied equipment may not be modified or used for
any other purpose other than, for which it was
intended. Use of the Allied equipment, other than
those specified in this manual, may place personnel
at risk of injury and/or may subject the equipment to
damage. The Allied equipment shall not be modified
or used in unapproved applications unless written
consent is received from the Allied Engineering
Department.

4.0 Product Information
4.1 Description and Typical Applications
The Allied Breaker is a hydraulic powered impact
breaker designed for mounting on mobile equipment
with hydraulic booms, such as rubber tired or track-
type construction vehicles.
The breaker is suited for many types of construction
and mining applications including -
Clearance Work: Demolition of buildings, bridges,
reinforced foundations etc.
Trenching: Breaking trenches out of rocky and
frozen ground.
Mining and Quarrying Applications: Demolishing
and leveling quarry rock, breaking oversized
minerals and other rock-like raw materials.
Excavation of rock from trenches, foundations
and tunneling.
Underwater: Demolition and deepening of
shipping channels. (Requires conversion from
standard type before underwater use!)
Recycling: Breakup of "skulls" from the steel
industry.
4.2 Familiarization of Components
Fig 4-1 Main Components of Hydraulic Breaker
4.3 Principle of Operation
Fig 4-2 Cutaway of Breaker Assembly
The Breaker is not self-powered. Performance
relies on a host machine, equipped with a
suitable hydraulic circuit that is capable of
achieving all requirements specified in the
technical data section of this manual.
Within the machine’s hydraulic circuit, an
ON/OFF valve is necessary to provide flow in one
direction to the Breaker. The valve will be
managed with a momentary switch located in the
operator’s cab within easy reach of the operator.
Opening the ON/OFF valve permits oil to flow
from the machine’s pump to the port marked [IN]
on the valve housing.
The breaker's operating valve directs incoming oil
to the lower end of the cylinder. The piston will
rise as the oil becomes pressurized.
The operating valve is open while the piston is
cycled upward. Oil in the upper end of the
cylinder exits the breaker and is returned to the
machine’s hydraulic tank.

4.0 Product Information –[cont’d]
The breaker is equipped with an accumulator.
The accumulator is a self-contained pressure
vessel with an expansible chamber divided by a
flexible membrane. The gas-side chamber is pre-
charged with nitrogen gas (N2), while the oil-side
chamber is for receiving, storing and discharging
pressurized oil.
As the piston nears the top of its stroke, signal
ports inside the cylinder become pressurized and
shift the operating valve. Oil is blocked from
exiting the upper end of the cylinder. The valve
directs oil to the upper end of the cylinder and the
oil becomes pressurized.
Pressurized oil supplied by the pump and
combined with the discharged oil from the
accumulator drive the piston downward until it
impacts the tool.
The cycle is continuous until the machine
operator releases the momentary switch
controlling the ON/OFF valve.

5.0 Sizing the Breaker
The process of selecting the right breaker must
consider the type of work to be done, along with any
special needs such as required modifications when
working in underwater applications.
When sizing the breaker, there are generally three
key points to consider –
Production rate (Type of material to be broken)
Lift capacity of machine
Hydraulic capacity of machine
Obtaining optimal production rates requires efficiency
between the breaker and machine. Other factors
include pairing the right size breaker to match the
material’s hardness and the required degree of
material size reduction.
Materials are fractured by two methods – Penetrative
and Impact. In penetrative breaking, blows from the
piston drive the tool into the material and wedge it
apart. With impact breaking, the blows from the
piston generate compressive stress waves that travel
through the tool and then transferred into the
material, causing it to fracture.
Be careful not to undersize the breaker in hard
material. It is important that the entire impact force
(the stress wave) is transferred into the material. If
not, it will be reflected through the tool and back into
the breaker.
Ideally, it should take 3- 5 seconds to fracture the
material. Anything less than 2 seconds puts the
breaker at risk of idle blows. Running the breaker
continuously beyond 15 seconds will generate
unwanted heat at the tip of the tool.
Using an undersized breaker in very hard material
will negatively impact production as well as
component longevity and reliability. In hard rock
applications, undersized breakers are subjected to
longer running cycles. This generates inefficiencies in
both the machine and breaker. In extreme conditions,
monitoring the condition of wear parts, such as
bushings and tools, will need to be more frequent.
The machine’s service intervals will also require extra
attention.
Production is negatively impacted if the host machine
is too light for the breaker. If the machine is
undersized, the operator will need to work slower to
keep the machine stable. An undersized machine
also limits the amount and size of the material that
can be moved by the machine when raking or
repositioning materials.
Provided the carrier can safely lift the weight of the
breaker, hydraulic comparisons are another key
element for successfully matching the right size
breaker with the carrier. The combination of a
suitably matched hydraulic circuit that is in good
service condition will help to ensure heat generation
and power loss in the hydraulic system is minimal.
It’s important to complete several tests and evaluate
the performance of the hydraulic circuit before the
breaker is used. All hydraulic breakers are designed
to provide optimum performance with reliable service
life at a specific oil pressure and flow range. Before
use, it’s important to review and compare operating
specifications of the breaker with those of the carrier.
The breaker must not be used until testing is
completed and the results confirm the hydraulic
circuit is properly calibrated and set in accordance to
the specifications including oil flow, operating
pressure and back pressure.
Flow requirements and other specifications of the
breaker, including weight, are located in the
Technical Data section of this manual. Tools required
for testing the hydraulic circuit include a flow meter
and pressure gages. An overview of the testing
procedure, along with a form to record the results of
the flow test, can be found in the Technical Data
section in this manual.
Other important considerations include knowing how
your machine is equipped and if any modifications
have been made. Factors such as boom and stick
length, undercarriage and tracks, counterweights,
etc., all affect the lifting capacity of the carrier. Also,
remember to take into account any add-ons such as
a quick attach coupler. Consult the manual provided
by the carrier manufacturer for specifications.
5.2 Auxiliary Circuit and Conversion Kits
Hydraulic work tools, such as Breakers, are not self-
powered. Performance relies upon the host
machine’s ability to provide a suitable hydraulic circuit
that will achieve all requirements specified in the
technical data section of this manual.
Most machines will require some level of conversion
to make use of their hydraulic power. A hydraulic
circuit, capable of producing flow and pressure in one
direction is needed to operate a breaker.

5.0 Sizing the Breaker – [cont’d]
Conversions to machines equipped with a factory or
dealer installed auxiliary circuit may require little more
than minor adjustments to flow and pressure settings.
Follow the machine manufacturer’s instructions for
adjustment procedures.
Fig 5-1 Allied Conversion Kit With AC-Series Valve
If the machine is not equipped with a hydraulic circuit,
a conversion kit, from Allied, can be installed. When
necessary, Allied conversion kits include the Allied
"AC" series valves. These are solenoid-operated
valves that control flow and pressure.
Requests for further information or assistance with
breaker selection should be directed to your Allied
dealer or by contacting the Allied Sales or Product /
Technical Support Departments.
CAUTION
Hydraulic circuits differ between
machines. Improper oil flow or pressure
can damage the breaker or carrier.
Only qualified personnel, having knowledge of the
machine’s systems, proper test equipment and tools
should perform conversion set-up and adjustments.
