culvert cleaning machines are built to clean culverts, covered canals
and sanitary drainage networks. They were solely designed by DMMAS
engineers. We partnered with Sakr
Factory for Developed Industries; a subsidiary of The
Arab Organization for Industrialization to manufacture
a system that satisfies the requirements of The
Egyptian Ministry of Water Resources and Irrigation.
Ten machines were built in the year 2005. They have been in effective
service since then.
culvert cleaning machine consists of two basic units; a front unit
and a rear unit. The two units are connected to each other by a steel
wire. Accessories include a twin-jaw bucket and a trailer. The steel
wire is meant to pull the bucket back and forth inside the culvert
so as to affect cleaning. Power is provided to each unit through a
hydraulic crane driven by a Diesel Engine. The suspension of each
unit comprises an axle, two tires, two leaf springs, a foldable castor
wheel, two front jacks and two rear jacks.
its jaws open, the twin-jaw bucket is pulled backward by the rear
unit. This allows the collection of the material clogging the culvert.
The two jaws are then closed and the bucket is pulled forward by the
front unit. Equipped with a slide and a shaker, the front unit lifts
the bucket and discharges its content into the trailer.
brands are available; CCM-15/15 and CCM-35/35.
The figures indicate the engine power for the front and rear units
respectively. However, any other power combinations can be arranged
for so as to suit the target application.
front unit is 4.820 meters long, 2.140 meters wide and 2.955 meters
high for both brands. It weighs 2.560 tons for brand CCM-15/15.
Equipped with a Diesel Engine of higher power, brand CCM-35/35
front unit weighs 2.745 tons. Keeping the same width as the front
unit, the rear unit is 4.485 meters long and 2.59 meters high. It
weighs 1.93 tons for brand CCM-15/15 and 2.121 tons
for brand CCM-35/35. The 12 mm-diameter steel wire
connecting the two units is 120 meters long. Buckets of 250, 300,
500 or 600 mm diameter move at a speed ranging from 25 to 30 meters
hydraulic unit comprises a variable displacement piston pump and motor
operated at 250 bars.
planetary-type gearbox is used.
water-cooled Diesel Engines are used in both brands. Two 2-cylinder
26-HP engines are mounted in brand CCM-15/15
with two 4-cylinder 60-HP engines for brand CCM-35/35.
Power ratings are specified at 1500 rpm.
are discharged into a 2-ton-payload 2.25-cubic meter-capacity trailer.
