What are the SHARC Products?
The Multi-Ripper, SCARC
(SHanks-on-an-ARC) products, are the most powerful excavator rock rippers
and rock ripper bucket combinations on the market.
How do I benefit?
These products rip rock up to 4 times
faster than a hammer. They rip 10 times faster than a single pointed ripper.
They exceed all other designs of frost rock, or ripper buckets on the
market. They rip to all depths leaving relatively flat bottom and side walls
in the trench.
How do they do this?
The staggered shanks on an arc hit one at a
time allowing the maximum breakout to be applied to each tooth. The tooth
force is about 8.5 times that of a standard 5 tooth bucket because the
shanks are short. Also, the shanks are the same distance from the stick
pivot, so the shanks rip a relatively flat bottom.
Why should I believe that it works?
These products are patented in the US and
in many countries throughout the world. This design won several design
awards. Many customers have claimed this is the best attachment I've ever
bought.
The Multi-Ripper?
(not
a bucket) The MR has three or four short shanks that are wider than the
stick, arranged such that each tooth hits one at a time at the optimum
ripping angle. The MR is great for general rock or frost ripping, or open
areas, or when the excavator has a quick change coupler installed.
The Multi-Ripper Bucket?
The MRB is almost as powerful as the MR but
allows the operator to rip and scoop with the same attachment. The MRB is
about half the capacity of a conventional bucket, but has the ripping force
of about 7.5 times that of a conventional (5) tooth bucket. The capacity is
usually not an issue when ripping rock anyway, because the operator will be
happy to be able to rip and fill the bucket with rock.
The Hi-Cap Multi-Ripper Bucket?
The HCMRB is about 10% less powerful as the
MRB, but has the capacity of about equal to that of a conventional bucket,
(but still about 7 times more breakout force). This bucket is great if the
job is large and there will be at least two weeks of rock ripping involved.
This bucket can be used with a coupler, however, it works best if pinned
directly to the machine to achieve the shortest tip radius for maximum
breakout forces.
What is a single pointed ripper?
A single pointed ripper is usually longer
and has only one ripper. The shank is longer because the operator must move
the tool over to clear the linkage as the ripping gets deeper. This longer
length causes a loss of breakout force. There are still good applications
for these such as picking out boulders and ripping very narrow trenches.
What is a Single Pointed Ripper Bucket?
A
Single Pointed Ripper Bucket, now called our V-Raptor Bucket, is a narrow
Vee bucket used for ripping narrow V trenches in rock, plus having a
capacity for removing the ripped rock. The bucket is also good for stump
removal, prying boulders or slabs.
What is a DigNRip Bucket?
A DigNRip Bucket is the predecessor to the
Multi-Ripper Bucket. There are shanks on the back. The severe ripping effect
is similar except the front leading edge is about the same as a conventional
bucket so the teeth do not hit one at a time. Because the teeth are on the
back, the tip radius is a little longer and the visibility is less because
the operator cannot see the rippers. Plus, the DigNRip bucket always leaves
a layer of ripped material in the trench because the rippers are behind the
front leading edge. The Multi-Ripper Bucket rips the material and then the
loose material goes into the bucket leaving the trench clean. DigNRip
buckets are great for digging and loading such as a quarry or a rock pit
where high productivity removal of medium hardness rock is required.
What is a Multi-Ripper Tooth?
The Multi-Ripper Tooth is a vast
improvement over the conventional twin tiger rock ripping tooth. The tooth
is similar to a twin tiger style except twistedin order to produce high
penetration, yet still effectively rip the sides of the trench. No other
tooth provides the penetration of a single spike and the side wall ripping
like that of the Multi-Ripper Tooth.
Why is ripping the rock faster than using a hammer? Rock is usually very strong in
compression, but weak in tension. Concrete for example, is extremely strong
in compression, but like a piece of chalk, if pulled or bent, will break
much easier. Hammers put the material in compression, so the hammer has to
be very forceful in order to break the material. A ripper pulls the material
apart, so the force can be substantially less. As long as there is a place
for the material to go, the ripping can occur.
How do I know if these products will work with the rock, frost or coral on
our project?
If the rock is rippable, the products will work. So, if a dozer will rip the
material, or, you can gouge the material with a corner tooth of your bucket,
then the Multi-Ripper Products will work. If however, a corner bucket tooth
only glides over the surface, and cannot even scratch the material (like New
Hampshire bedrock granite slabs), then the Multi-Ripper products will not
work. We have found that most rock is rippable.
If I provide you information on the rock we have, like Blow Counts compressive Strength Seismic Velocity etc. of the rock that we have,
can you tell me if the rock will rip with your product?
No.
There has not been a good scientific method of comparing these compressive
measures with the rock strength in tension. Most of these measures relate to
the rocks compressive strength. Seismic velocity has been generally compared
to rippability, and this chart can be found in documents on the internet.
What is HARDOX and why is it used in your product? HARDOX is the brand name of a Swedish steel that has been vacuum purified to give the steel not only hardness, but toughness. AR400 for example, has not been vacuum purified, and has a tendency to de-laminate and crack if used as structural member. Most uses of AR400 are for armored products that need hard flat surfaces for wear and not necessarily for structure. HARDOX is great for wear, and for toughness. Adding extra plates or adding hard-facing is not necessary, and not recommended. Hard-facing can actually cause damage to the HARDOX material by inducing tiny cracks in the material, and will thus void our warranty. If any welding is required or desired, please contact LEA, Inc. Engineering for the special HARDOX welding procedure.
Where are your products manufactured?
Leading Edge Attachments, Inc. products are manufactured in Wisconsin, and
the Multi-Ripper Teeth are manufactured for us by MTG of Spain.
What do we do if some of the rock is not rippable?
Most rock is rippable, however, some is not, so many contractors may have a
machine that is plumbed for a hammer ready for those applications. Non
rippable rock must be broken using a hammer, or, with blasting. The more
rock that can be ripped with a Multi-Ripper Product, the better off you are
because a Multi-Ripper product is far more productive and requires far cost
less to operate, but, sometimes the use of a hammer is not avoidable.
Why can't I get any tooth that I want?
We have tested many teeth that are on the market, and because the force
produced at by a Multi-Ripper Product is so high, only the strongest teeth
survive.
How long will it take to get one for my machine?
If we do not have the unit in stock, we will have to manufacture the unit to
order. We many times have the base portion built up in advance so that we
only have to add the top lugging to fit your machine. Our manufacturing lead
times are better than most companies in our industry, so please call to find
out how fast we can provide one for your machine.
Are these units in stock?
We do make some units for stock, however, because we make them to fit all of
the excavators and backhoes per OEM specifications, it is hard to
predetermine in advance what will be ordered, so please call to find out
what is available for your machine. Our lead times are much shorter than the
industry average.
Do they come with linkage pins and teeth?
The units do come with one set of teeth, but they do not come automatically
with coupler dead pins. Coupler non-greasable pins can be ordered separately
if you have a coupler.
Do you make them for other types of couplers?
We make them for almost all coupler types except Bobcat. We do make them for
the Bobcat skid steer units however. Please call to find out more.
What other products do you offer?
We are affiliated with Woods Equipment Company, so we can provide almost any
common excavator, backhoe, skid steer or wheel loader attachment. We also
make attachments by special order, so please call to find out if we can make
the attachment for your special application.
