Brian
Clark notes that the recently introduced DP
75 Hwall saw is an ideal option for the clinical
non-destructive removal of concrete to create
openings in the civil industry applications.
"The saw consists of an 800 mm diameter
blade, which can cut reinforced concrete
and masonry to a depth of 320 mm. Another
feature is a high frequency motor can be
disconnected from the machine in less than
two minutes without the need for any tools,
in order to reduce the carrying weight for
the operator."
Clark explains that the saw comprises
of a cutting head, tracks and power pack,
which are manufactured from a torsion rigid
aluminium, with stainless steel taper gibs,
while power transmission is achieved by an
oil-lubricated gear with an integrated over-
load clutch in its rotating arm.“The blade and
the feed operations are electrically driven by
a three-phase 380 V motor, which eliminates
the need for costly, bulky hydraulic power
packs onsite."
According to Clark, the electric motor is
a high-cycle motor, which provides greater
watts to increase the power of the saw with-
out sacrificing its lightweight. "The saw is
easily portable, making it suited to theAfrican
market where more and more jobs are done
in confined spaces. Due to its fast set-up, the
DP 75 H wall saw provides improved pro-
ductivity, while its electric design eliminates
leaks that occur when many hydraulic wall
saws are used."
Diamond Products co-director Darryl
Gray notes that the DP 13 HP-400 concrete
saw is another suitable option that is more
competitively priced than similar competi-
tor products, while maintaining the highest
standards of quality. "The machine can be
fittedwith blades as large as 400mm, thereby
ensuring respectable cutting depths, and
is ideally suited for repairing pot holes and
cutting neat curbs or trenches across roads
for pipe laying," he explains.
Gray highlights the fact that the DP 13
HP-400 concrete saw is powered by a 13 hp
Honda engine, which provides customers
with further peace of mind with regards to
reliability and parts availability. "The simplic-
ity of themachine is anothermajor advantage
to smaller contractors, as it has a minimal
amount of moving parts, and can be easily
loaded onto the back of a bakkie. The DP
13 HP-400 concrete saw is completely stand

and equipment for industrial applications.
alone and even houses its own water tank to
keep the blade cool in rural conditions where
water supply is difficult to come by."
According toGray, a super-rigidbox frame
ensures straight cuts while resisting warping
and vibration, which ultimately prolongs
the life of the saw and the blade. "Additional
features of the DP 13 HP-400 concrete saw
include; ergonomically designed height
adjustable handles and easy crank for raising
and lowering cutting depth, in addition to a
hinged front lift-up blade, which is designed
to provide easy replacement," he continues.
The new DP 13 HP-400 concrete saw fits
in perfectly with Diamond Products MAX
range of cuttingblades, which offer increased
value-for-money, due to the fact that it comes
standardwith a 14mmdiamond segment, as
opposed to the industry standard of 10 mm.
“In the plant hire industry, it is important
to stock equipment that is reliable and
durable, and the 14 mm diamond segment
ensures a significantly increased lifespan for
the blade, thereby providing the plant hire
company and its clients with a high qual-
ity and cost effective floor cutting product,"
notes Clark.
The Max Blade range, which is capable
of reaching a cutting depth of 125 mm on
concrete and tar surfaces, is ideally suited
to medium sized applications that do not
require large capital equipment. Gray notes
that over the past 20 years, the construction
industry has moved away fromowning small
plants in order to save on overhead costs.
"This means that small plant hire has devel-
oped into a big industry in South Africa and,
thanks to the innovation and quality of the
Max Blades range, Diamond Products is able
to satisfy the needs of both the supplier and
the contractors.”
