CONMACO is the recognized
leader in pile driving equipment since its founding in
1907. Our line of single acting steam hammers with energy
ratings of up to 1,500,000 ft-lbs has been developed as
a direct result of extensive experience in the sale and
rental of pile hammers to leading contractors throughout
the world.
- Our hammers combine features such as the auto/stop
and energy selector that not only increase service life,
but decrease and simplify maintenance and repair as well.
- In addition to our air/steam single-acting hammers, CONMACO offers
diesel, hydraulic impact and vibratory hammers and extractors
- At CONMACO, we have our own pattern equipment
and we have developed a complete line of helmets for
our hammers as well as others currently available to
the industry.
Our experienced engineering staff
can design special helmets for any purpose.
As a full service representative for PTC Vibro Hammers,
Conmaco can now offer the Patented High
Frequency Variable Amplitude line of hammers. These
hammers are ideal for working in sensitive environments
where the vibrations transmitted to surrounding areas are
a concern. They also allow you the flexibility of
using telescopic boom cranes due to the elimination of
vibrations transferred to the crane boom.

{a}
Hammer operating speed is a function of many variables,
including penetration resistance, cushion material,
pressure, stroke, etc. Observed
blow-count will vary depending on driving conditions. Energy
is not a function of speed. |
{b}
Compressor output must exceed air required at hammer
due to line and efficiency losses. It is advisable
that the adiabatic consumption figure be increased
by approximately 30% in the determination of the
of the required compressor size. |
{c}
Steam consumption is based on feedwater and steam
temperature of 212o F. |
{d}
Standard Female Jaw dimensions are shown. Male
Jaws are available on special order. |
