These 11 attachments can add a new dimension to your excavators, enabling them to be more productive on demolition jobs, site work and a variety of other tasks.

These tools can separate rebar from concrete, enable buckets and other attachments to rotate and tilt, or boost your excavator’s lifting power, among other capabilities.

Demolition

Epiroc Bulk Pulverizers are designed for secondary demolition and reduction of reinforced concrete elements. (Photo shown at the top of this story.) Featuring an angled shape and broad jaw, the pulverizers help speed up work to enable clean separation of rebar and concrete. Epiroc’s range includes two bulk pulverizers for carriers from 18 to 40 tons. They can reduce material into grain sizes suitable for crushing or use as backfill. The pulverizers’ cutting blades are replaceable and reversible. A 360-degree hydraulic rotation device is optional.

NPK Concrete CrusherNPKFor excavators in the 21- to 50-ton range, NPK Concrete Crushers are designed to crush through reinforced concrete to separate concrete and steel rebar. They are designed for primary and secondary demolition and recycling. Features include abrasion-resistant, high-strength, alloy steel teeth, optional 360-degree hydraulic rotation, NPK’s Hydraulic Intensifier System for faster cycle times, and a bolt-on replaceable tooth plate on the movable jaw. The “A” model also uses a bolt-on tooth plate on the fixed jaw.

Komatsu JMHB-V breakerKomatsuKomatsu’s new JMHB-V breakers are designed for rock and concrete demolition. The hydraulic breakers modulate their impact force and frequency with up to 16 working positions to match the task. They are also fitted with a recovery valve that recuperates energy to drive efficiency. Depending on the application’s hardness, V-series breakers automatically select the best piston stroke length and speed, the company says. Standard features include automatic greasing, advanced blank firing protection, swivel hose couplings and heavy-duty housing.

RJB Hydraulic Hammers’ HK45 breaker with combo bracketRJB Hydraulic HammersRJB Hydraulic Hammers has designed a combination mini-excavator/skid steer bracket for its HK45 Hydraulic Hammer for carrier machines of 3.5 to 6 metric tons. The company says it produced the bracket in response to feedback from rental yards where the HK45 is the company’s most popular hammer for short-term rentals. The HK45 is a 1,000-foot-pound impact class hydraulic hammer. It can handle larger concrete jobs. It comes with a tool diameter of almost 3 inches. 

Tiltrotators

Caterpillar TiltrotatorCaterpillarCaterpillar says its Tilt Rotate Systems are an industry-first with fully integrated technology for its Next Generation 306 CR, 307.5, 308, 308.5, 309 or 310 compact excavators. The tiltrotators can tilt left and right 40 degrees and rotate 360 degrees, allowing work at various angles without the need to reposition the machine. The devices help improve productivity. Models come with pin-on or S-type coupler top interfaces and S-type coupler bottom interfaces. An optional grapple module allows the operator to move materials out of the way.

Takeuchi TiltrotatorTakeuchiTakeuchi’s new tiltrotator line consists of the DF4, DF10 and the Prop Plus models. The Prop Plus can run both tilt and rotate functions as well as a hydraulic coupler and multiple auxiliary functions using only the excavator’s primary circuit without a separate control box. It comes with two joysticks and a monitor. It can work with a grading system. The DF4 runs tilt and rotate functions with two hydraulic circuits and a control box in the cab. The DF10 can run the same functions as the DF4 without a control box but requires a separate hydraulic circuit for each function. 

Buckets and such

Werk-Brau Skeleton Rock BucketWerk-BrauWerk-Brau’s new Skeleton Rock Buckets are designed to separate large rock and other debris from smaller loose materials. They are available in various widths and sizes for excavators or loaders. They are manufactured with high-strength T-1 steel in all critical wear points, with abrasion-resistant wear straps to reinforce the bucket bottom. Tapered side plates reduce wear on the bucket and allow for easier dumping. The buckets are ideal for quarry work and anywhere that larger materials are sorted from smaller loose materials.

Yanmar Stowable Utility HookYanmarYanmar’s Stowable Utility Hook provides a factory-designed lifting point for the company’s compact excavators, from ViO25 up to the SV100, without the need to use an attachment. It reduces the risk of damage to the machine, buckets or other attachments resulting from attempts to lift heavy objects with a strap or chain connected to areas not intended to be lifting points, the company says. The hook features a multi-directional design that allows it to swing in each direction and swivel 360 degrees. The swivel hook stows out of the way with a lock pin.

Bedrock Attachments’ Long ReachBedrock AttachmentsBedrock Attachments says it has a warehouse full of long reach booms and sticks for excavators. The long reaches range from 18 to 22.86 meters long for various Caterpillar, John Deere and Hitachi  models. Bedrock uses computerized analysis for the stress distribution of the long reach and to optimize the design. It uses large milling equipment to improve welding. The hydraulic-oil pipes are made of cold-rolled precision steel and are finished by phosphoric acid washing to make the pipes smoother for reduced flow resistance and oil circuit pollution.  

Danuser EP Auger System with Stump AugerDanuserDanuser’s EP Auger System for excavators features a planetary gear drive with greater torque for drilling through hard surfaces. The system is compatible with Danuser’s new Stump Auger, which planes away stumps. A threaded pilot digs into the stump, and large cutting blades shave the stump away. The blades are reversible. EP Auger System models range from 6 to 35 gallons per minute of hydraulic flow and from 1,500 to 3,500 pounds per square inch of pressure. The stump auger is available in 10- and 16-inch diameters.

TVH Americas bucket cutting edgeTVH AmericasTVH Americas offers a selection of reversible, double-bevel, bolt-on cutting edges to help extend the life of buckets for light construction equipment. The edges are made of high-quality steel and come in an assortment of widths and lengths. The bolt-on cutting edges can be rotated or replaced in less than an hour with basic hand tools. A double-sided, or reversal, blade can be rotated to give users essentially two blades in one. The blade also lifts the bottom up off the ground slightly, reducing the amount of drag and wear on the bucket.

When your roof finally comes of age, and it’s time to re-shingle and replace it, many people don’t understand what they are trying to evaluate. Many people think that shingles are shingles and may pick them based on the style or color. However, they may not know why some shingles are recommended for their house or area over others. You should ask your roofing contractor a lot of questions about shingle types and what’s best for your house style and the area where you live. You should be well informed when you step up to bat to put a cap on your house.

You should consider these structural factors

Weight limits of your house

While shingles are often seen as light compared to the components of the rest of the house, the fact is that they are frequently a considerable portion of the mass of a house. Not all houses are built to support all types of shingles. The weight limit of most typical house roofs is around 15 pounds per square foot of roof, which is a reasonably robust but not infinite amount of weight. Some heavier types of shingles can easily exceed this mark, and older houses that haven’t been kept up properly could shudder and shake under that kind of weight.

So, knowing the per-square-foot weight limit of your roof is going to be a large part of making the right choice to keep your home dry and standing for years to come.The slope and pitch of your roof

First off, let’s make sure we’re understanding these terms correctly. The slope of your roof is the amount the roof rises in inches for each foot of its depth into the house, so a house with a roof that rises one inch per foot would have a very shallow slope, whereas one that rises eight inches per foot would be incredibly steep. The slope is expressed as a ratio, 1:12 for the first house and 8:12 for the second.

The pitch of a roof is a fraction that represents the rise of the whole roof from edge to peak over the entire span of the roof. So, a roof that was 100 feet in span that rose 10 feet up would have a pitch of 10/100 or 1/10.

Depending on the pitch and slope of your roof, certain types of shingles might not be appropriate for your house. Larger clay and stone shingles, for example, might slide right off a steeper roof or have trouble staying in place in the long term. Again, this is something you should know before you go shopping to avoid setting your sights on something that’s not available for your home.

Environmental factors to consider

Where your home is in the world and what the environment is like will have a significant impact on what types of shingles you want to protect your roof. For example, a set of shingles that works beautifully for houses in a dry, warm climate like the Southwest might be inappropriate for a house that has to endure the cold winters and snow of the Mideast. Likewise, different kinds of tiles will provide different benefits and last different amounts of time depending on where you are in the world. So, it’s worth taking a beat to plan that out for yourself.

How much snow and rainfall does your region have each year?

The amount of snow or rain that falls on your roof is going to determine how appropriate certain types of shingles are for your area. For example, wood shingling will be better suited for a drier climate than most asphalt, rubber, or plastic roofs will be due to the increased pressure from bugs and mold that is going to be applied to even the best antifungally treated wood shakes.

A large amount of freezing and thawing will put a lot of strain on clay or stone roofs that would otherwise last an incredibly long time. So, while it won’t make them useless, it’s essential to recognize how precipitation is going to inform the longevity of your purchase.Are moisture and algae a problem in your neighborhood?

In a similar vein, different colors and materials are better equipped to deal with algal growth in moister areas where that’s likely to be an issue. It’s worth looking around your neighborhood to see whose roofs look the best in your local environment. It’s hard to beat the information you’ll get from looking at an older roof in your area because their owners have made similar choices and their roofs have been subjected to the same pressures yours will face.Winds—how high are they where you live?

If your area is subject to high winds, as in coastal environments or the Midwest, it’s worth considering whether your shingles might actually just blow away. Lighter types of shingles, such as plastic shingles or light metal roof panels, can be snatched up by fierce winds and tossed away. This makes it very worthwhile to invest in heavier shingles that will stay tightly latched to the roof and is one of the reasons slate and clay tiles are frequently so popular in coastal areas.The temperature range in your area

Last, the temperature of your environment is going to have a considerable impact on your choice. In hotter environments, clay and stone shingles can have significant cooling properties, which can help keep your house comfortable in hot summers but might make them less than ideal for places with sharp, brutal winters. The color of your shingles can also modify this a great deal, with darker shingles absorbing more heat from the sun and retaining it through the day, while brighter colors reflect more of the heat away from your house.

Make sure that you consider your house’s environment as you think about what you want it to look like.

Lifestyle factors to consider

A roof is more than just the hat that keeps your house warm. It’s also one of the most obvious statements that your house makes to people who visit you. So, it has to match the style of your house, and it has to look good with the color of the house.

Style

A house that has a hyper-modern aesthetic might struggle not to clash with slate roofing or wood shakes. Your house is the most significant stylistic choice you make in your life, and you don’t want to purchase something that makes it look questionable. That said, if your roof has a higher pitch, you have more visible surface area to play with, and the flatter your roof is, the less visually important the color of the roof is likely to be.

If you have a flat roof, a duller color could let the eye focus elsewhere, and a sharper color could be harder to pull off. In contrast, a taller roof gives you the opportunity to strike out with a color or tone with your choice of shingles.Neighborhood blend

You also want to make sure that your choice is not going to cause problems with your neighbors or make your house stand out in a bad way. For example, being the only house with bright orange clay tiles in your neighborhood could be lovely, but if it’s a clash with the houses around it, an otherwise lovely-looking roof could be made to look gauche.Maintenance needs

Certain types of roofs, most notably wood, clay, and slate, all require more constant maintenance and attention to keep them in order. If you’re not going to be happy to be taking care of your roof in a more active way, then perhaps these might be more of a headache than you actually want to deal with.

Costs

Finally, we get to brass tacks and cost. Depending on how long you plan on staying in your current home, certain purchases may simply not make sense. For example, you can pay more for much more longevity on your roof, with some stone roofs getting up to 200 years of durability with proper maintenance, but if you’re not planning to hand your house on to your heirs, it may not make complete sense to pay for a century of use that you’re not going to use. Similarly, solar tiles are a potential boon to a homeowner, but the precise economics of them may or may not make sense for a particular homeowner.

TypeCost per Square (100 sq./ft.)LifespanAsphalt$350 – $50020 yearsRubber or Plastic$550 – $1,10030 yearsMetal Panels$600 – $1,20050 yearsWood Shingles or Shakes$80030-40 years based on maintenanceSolar Tiles$2,100 – $2,500 (additional electrical wiring costs)30 yearsStone and Slate$1,50070-200 years based on maintenanceClay$1,50050-100 years based on maintenance

Now you’re armed to go forward and shop for a new roof, knowing what you need to get started on the journey of picking a roof that will keep you dry and warm for at least the next twenty years.
