Figure 2-1. Typical Street Hammer Main Components

2.1 Introduction
The Allied Street Hammer is designed for
use on backhoes, skid steers and
mini-excavators. It is compatible with
carriers weighing 2,000 to 30,000 lbs. (900
to 13,600 kg). The hammers can be in-
stalled on almost any hydraulic system and
can be operated with pump capacities from
4 to 24 g.p.m. (15 to 90 lpm).
The maximum operating pressure is 1900
to 2200 psi (130 to 150 bar). Most of the im-
pact energy is derived from the nitrogen
gas pressure in the head rather than the
hydraulic pressure. See Section 4-1 Tech-
nical Specifications for specific carrier in-
formation.
The Allied Street Hammer is an impact
hammer featuring high single blow energy
and long stroke design.
In place of side plates, the Allied design
suspends the hammer’s working body in a
box enclosure. This isolates the vibration
forces, allowing the hammer to work more
efficiently and reduce vibration to the car-
rier.
2.2 Description of Assembly Groups
•Cylinder Head
The Cylinder Head is the upper hammer
section.
The nitrogen filling and measuring fit-
ting for the precharge chamber is lo-
cated on the front of the Cylinder Head.

•Cylinder Body and Control Valve
The Cylinder Body, Control Valve and
upper seals fit inside the Cylinder
Housing. The lower seals are contained
in the bottom of the cylinder body.
•Cylinder Housing
The hydraulic pressure connection is lo-
cated on the front of the Cylinder
Housing. Connection P.
The hydraulic return connection is lo-
cated on the front of the Cylinder
Housing. Connection T
The demolition tool and tool bushing are
installed in the bottom of the Cylinder
Housing with a retainer pin and roll pin.
The lubrication fitting is located on the
Cylinder Housing. Refer to Section 8.5
for lubrication instructions.
•Piston
The piston reciprocates in the cylinder
body transferring its energy to the de-
molition tool upon impact. The upper
end of the piston has an identification
number which is explained in Figure 2-6.

SECTION 3.0
THEORY OF OPERATION
Figure 3-1 is a diagram of basic Street
Hammer operation illustrating how the
piston is moved up and down to impact the
demolition tool.
Up and down piston travel within the cylin-
der is controlled by hydraulic pressure
above piston surface f2.
·When the pressure above surface f2 is
low, the high pressure against surface f1
forces the piston up the cylinder. This
movement also compresses the nitrogen
gas, increasing pressure on piston sur-
face f3.
·The upward piston movement causes a
control valve (not shown) to shift posi-
tion. This shift results in a high pressure
above surface f2.
·When the pressure above surface f2 is
high, the piston is forced downward. The
nitrogen pressure against piston surface
f3 also drives the piston downward with
even greater force.
·Just before tool impact, the control valve
shifts again. This shift results in a low
pressure above surface f2.
