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.


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.
