users will find a lot of similarities. We have only one radio
control that allows the operator to position and drill –
one console does everything. One remote does the rig,
drilling, movement, carousel. This is very unique.”
Guardigli says the MC 20 A is largely used for shoring
up temporary walls that must be built to facilitate excavation.
It is particularly useful for urban high-rise projects
that emphasize vertical construction.
According to company materials, the carousel handles
up to nine pairs of rods and casings with varying
diameters, reaching a maximum drill string length of 30
metres. When drilling and grouting are completed, the
carousel remains loaded and ready for the next bore hole,
with no need for an operator to handle the drilling tools.
An advanced articulation system provides flexible movement
and the MC 20 A can even reach low entry points
for horizontal drilling, according to Guardigli. Even
in confined spaces the rig is stable, with an oscillating
undercarriage that adapts to uneven ground conditions.
The MC 20 A is powered by a 285-HP engine that complies
with European Stage V emission standards, running
a 200 litre per minute flushing pump and a dual head
system simultaneously. Operators can use the electronic
bore management system to shift the power to a different
application. With its powerful engine and a variety
of accessories from Comacchio, including single rotary
heads and hydraulic drifters, the rig can be specially
equipped for any client.
Guardigli says the first MC 20 A will join the Canadian
Pile Driving Equipment rental fleet in Montreal this
spring, which also includes an MC 22 A. He predicts
the North American demand for the MC 20 A will be
around 10 machines annually. The new rig has already
been introduced in the U.S. by Comacchio dealer ICE
(International Construction Equipment).
“It is a high performance machine in the upper price
segment,” said Guardigli. “It’s not for everyone. It is for
professional customers willing to invest in safety.”
He says that the main advantages of the MC 20 A when
compared to similar machines on the market are its compact
size, ample power and lower overall weight.
Lightweight capability: CH 320
Comacchio has also released its CH 320 piling rig, targeted
at the large diameter sector. The manufacturer
began building equipment for this segment in 2015,
releasing five models in five years.
The CH 320 offers many advantages in the field.
Among them are its transport weight of less than 32
tons/70,500 lb (with rotary and Kelly bar installed) and
self-erecting capability. Guardigli says it can be unloaded
and put into operation in just a few minutes without the
need for any external equipment. A variable gauge undercarriage
with telescoping side frames further stabilizes
the rig during set-up and drilling.
Despite its smaller size, the CH 320 is mighty. It offers
high torque performance – up to 132 kNm of nominal
torque – allowing users to complete drilling tasks that
would normally call for bigger equipment.
On the job, the CH 320 shines for completing drilled
shafts with the use of casings in areas with soft soil or
where water is present. Working with casings up to 880
mm in diameter, it offers a winch pull down system
that allows for a Kelly set-up, as well as a quick-CFA
configuration with a special conversion kit that permits
the installation of CFA piles with an 800 mm
“The CH 320 emphasizes energy efficiency and sustainability,”
said Guardigli. “Operators can efficiently
control the power supplied by the pumps, which significantly
reduces fuel consumption. It’s estimated to save
around 30 litres per day.”
The engine also conforms to Stage V emissions standards
and the CH 320 offers a more spacious, updated
cab design while fully complying with relevant safety
standards. The adjustable workstation offers a seveninch
colour touchscreen that connects to user-friendly
control software, custom designed by Comacchio.
“The software allows the operator to manage every
aspect of the machine, from fault diagnosis to drilling
parameters,” said Guardigli. In addition, it can be configured
for real-time performance evaluation, which
allows for data analysis, production reporting and
With its CH line of piling machines, Comacchio is
expanding its solutions for large diameter drilling. In
total, the manufacturer builds more than 80 drill rig
models, with a commitment to continuous improvement.
Comacchio has more than 30 dealers worldwide. The
first CH 320 in the U.S. will soon join the rental fleet of
Hammer & Steel.
Comacchio is expanding its dealer partnership
with Canadian Pile Driving Equipment (CPDE),
headquartered in Lacombe, Alta., about 25 km
north of Red Deer. The arrangement will see the
company providing more Comacchio drilling
equipment rentals to its Canadian customers.
Currently, there are about 50 of the Italian-made
rigs in the country, representing various models.
“It’s difficult to work in Canada because the
country is so spread out,” said Piero Guardigli,
Comacchio’s sales agent for North and South
America. “Comacchio has been in Canada since the
early 2000s. I rely on having good people in the
field. I’ve known CPDE for a long time and they’ve
been working with us in the west for a while. Now,
we are expanding to Quebec with them as well.”
