SWOBE has a Rock Cutter for quiet excavation of rock and concrete with minimal vibration.
Rock Cutters are also known as Twin Headers or RoadHeaders or Rock Grinders - To view some videos of similar equipment from other sites on the internet click here
Our Rock Cutter is the first of it's kind in Australia, Stephen Koelewyn has gone well beyond the conventional with this piece of equipment, he now has a piece of equipment that is easy to transport from site to site, can access any area under 1950mm high and 1300mm wide.
Considering excavation under a building or digging a pool in rock or just need to break up concrete then you may want to give us a call. We primarily service the southern areas of Sydney.
Steve hits
concrete with the Montabert CUT-20
mounted on his
Avant 635
loader.
The Twin
Header Concrete Cutter goes through the concrete with little resistance and
virtually no vibration to the surrounding areas.
Our
Avant 635
is an ideal machine for carrying the Twin Header Rotary Concrete Cutter as the
machine has an extendable boom that allows for controlled reach and the
Avant 635
articulates to the centre of the machine giving precise side to side action, the
machine weight proves to be ideal in providing cutter with plenty of down force
on the work face.
Within
minutes a trench can be cut in the reinforced concrete, minimal dust was
generated and noise levels of the cutting process were less than the noise of
the revving
Avant 635
The
Avant 635
remains totally stable even when fully articulated and the boom is fully
extended together with the Montabert Cut-20 Twin Header Rotary Rock Cutter, we
are able to easily cut rock and concrete to heights of 4 meters, this on a
machine that is only 1300mm wide is a considerable advantage and allows access
where other larger machines can not be considered.
The
Montabert Cut-20 Twin Header Rotary Rock
Cutter hits rock, Sydney, Australia has sandstone containing Quartz and
sediments that have differing degrees of hardness, the rock cut in this instance
is of medium hardness, the chipping of the rock was like a walk in the park, the
rock cutter milled this rock with ease, not the
Avant 635
machine was on a considerable incline at the time of operation.
Excavation through 120mm concrete and underlying rock for new drain pipes cut to
depth in minutes, all excavated material is milled rock and concrete that can be
reused for backfilling around the pipe, using the
Montabert Cut-20 Twin Header Rotary Rock
Cutter has proved to be far superior to the use of a hydraulic hammer, the
surrounding concrete has no fracture cracks due to vibration, existing inground
services can be readily exposed with significant less risk of damage to the
existing services and nearby brick structures were not exposed to any vibration
at the time of concrete and rock cutting.
With 50+
Rock picks installed on the Twin Header of the rock cutter the efficiency of
this machine is truly impressive.
We have
been advised by the Montabert Sydney
distributor, Attachments
Australia, that this is the first
Montabert CUT-20 to be sold in Australia. The
Avant
Importer/Dealer located at 9 O'Neil Street, Unanderra NSW (+61-2-42726853)
advises that this type of attachment has never been used on this type of
machine. As far as we are aware the Twin Header Rotary Rock Cutter has not been
used commercially on any Skid Steer or Loader machine in the world.
I sought information on this type of attachment from around the world, I narrowed my choice down to a Simex or a Montabert, the delivery times of Simex were some 6-8 weeks, Montabert was readily available ex Melbourne, having owned a Montabert Hydraulic Hammer for many years now, I was comfortable with the brand - my final choice was to purchase a Montabert. It would appear that all the Rotary Cutter attachments are so close in specifications that it is possible that all cutters are actually manufactured in only one or two plants somewhere in Europe.
In our
search for a solution to particular problems I have encountered when carrying
out repairs or making improvements under buildings as part of my Sub-Floor
Solutions, whether it be for underpinning of foundations work, termite work or
excavation of basements, this added equipment provides me with an ideal solution
to unique circumstances, this equipment in addition to my
Vacuum Excavator, Pest Control Rig, Hammers,
Auger, Grapple Bucket, Excavator, Stump Grinder,
SkippyBAG etc' gives me unique abilities
where others simply can not provide a similar service. All this is in addition
to a vast knowledge base and experience as I am constantly inspecting building
on a day to day basis.
My
efficiency is key to my success, I maintain a variety in my daily workload that
enables me to be in an out of jobs, I seek to take on a task and finish the task
promptly rather than have heaps of bits I need to attend to later, I write my
reports at night so I am free to play all day.
I seek to
have the ability in future to be more efficient at excavating under buildings
for addition of a garage or a basement, home cinemas and the like, this will
provide people with a real improvement of their property and their life style.
Having been in the building Industry for over 30 years and being involved in the
Pest Industry since childhood, these changes of direction are only slight
variations to where I've been and where I am currently at.
Stephen
Koelewyn will always reinvest his hard earned income back into equipment and
advances to the Building and Pest Industries, a tradesman with the right tools
for the job will generally provide cost effective, quality work.
I hope that this page of my web site, and my web site as a whole, has been informative.
I would appreciate the opportunity to be considered as an option to provide
various services on your next building project.
Our Avant 635
is readily transportable on our trailer float that is attached to our 10 tonne
tipper giving us flexibility to go anywhere, anytime with minimal effort. Having
such a capable loader together with the capacity of our Tipper gives us a mobile
unit that is efficient and cost effective. Our
Vacuum excavator is transported on the tray of our tipper.
When working onsite with our Rock Cutter and/or other machinery, we can keep
areas clean and tidy at all times by utilising our
SkippyBAG in a
SkipRACK - both these items
have also been developed by Stephen Koelewyn.
We shall be adding pictures and more information to this site in the near future.
