Excavator (also called a “track-hoe”): This tracked machine is equipped with an “arm” with a bucket on the end that gives it the ability to reach out and down to lift or dig. It is capable of swinging in a full circle and commonly used in construction and excavating where material needs to be moved from one point to another.

Many times the material being removed is loaded directly on a truck for transport. These machines are also used to clear brush, construct trenches and lay pipe. Because of their traction and ability to travel over rough terrain, excavators are often fitted with attachments such as tree shears or grapples for tree removal.

Another popular demolition attachment is a breaker (also called a hammer), which breaks up concrete or rock. Manufacturers include Cat, Deere, Komatsu and Volvo, and this equipment is too common in building demolitions in the area of Miami Fort Lauderdale Florida.

The decrease in the use of wrecking balls in Miami Fort Lauderdale Florida is mainly due to the modern machines like excavators. Excavators have a rotating  platform called the house, where there are a boom, stick, bucket and a pivoting cab that swivel up to 360 degrees to crush, concretes on building structures. Small building demolition jobs like tearing down small houses or two or three storey buildings use hydraulic excavators. Excavators’ attachments like the buckets contribute to the efficiency of using excavators. Buckets are attached to a lifting hook of a crane for bulk materials handling in building demolition jobs.

Compact, or mini, excavator: The small brother to a large excavator, this machine is highly maneuverable, and able to get into buildings that larger excavators cannot. It has rubber tracks and digs trenches of smaller depths. It’s especially useful for working in gated backyards of Miami Fort Lauderdale Florida. Manufacturers include Kubota, Caterpillar, Deere, and Bobcat. Building Demolition Equipment Miami Fort Lauderdale Florida

Skid steer loader: This small wheeled loader can turn and maneuver in a tight radius. Skid steer loaders gain their name from having the ability to keep one side of the machine static while letting the wheels turn on the other side. This machine can lift its bucket high over the operator’s cab to load trucks. It can be outfitted with dozens of attachments including forklifts, augers, grapples, breakers and planers. Manufacturers include Bobcat, Case, Cat, and Deere. and this kind of equipment is used for companies in the area of Miami Fort Lauderdale Florida.

Compact track loader: This resembles a skid steer loader, only on rubber tracks, giving the machine the additional ability to work in muddy conditions.  These machines have become extremely popular over the past few years in Miami Fort Lauderdale Florida; manufacturers include Bobcat, Cat, Deere and Takeuchi.

Wheel loader (Also called a front-end loader): This machine has four same-size wheels and has a bucket that loads material into a truck or conveyor, as well as moving material within a job site. These machines vary in size and horsepower and include compact sizes that are highly maneuverable. Many of these machines are articulated, or hinged in the middle, allowing for greater maneuverability. With the addition of a tree shear, grapple, or other attachment, wheel loaders can also be used in building demolition work in Miami Fort Lauderdale Florida.  Forks are another common attachment. Manufacturers include Caterpillar, Deere, Komatsu, Case and Kawasaki.

Backhoe (Also called tractor-loader-backhoe or loader-backhoe): These machines have two working ends; the front end has a loader bucket (such as the wheel loader listed above) and the back end has a backhoe, which resembles the working end of an excavator. This versatile machine loads and carries materials, and digs of building demolitions in Miami Fort Lauderdale Florida. Attachments include forks for the loader end, and grapples and demolition hammers for the backhoe end. Manufacturers include Case, Caterpillar, Deere, and Komatsu. Building Demolition Equipment Miami Fort Lauderdale Florida

Dozer: This machine is a tracked vehicle used in excavation and construction to move or push soil and rock. Because of its tracks, it can move around in muddy, rough ground. This machine can be equipped with a ripper (a claw-like attachment) on the back that lets it move rock embedded in the ground, and can also be equipped with a winch for stump removal work. Manufacturers include Cat, Deere, Case, and Komatsu.

Buckets: Most common type attachment. Has the broadest use including raising, digging, and hauling. Buckets come in a variety of sizes, shapes.

Grapples:  Used for land clearing and material handling.  Great for sorting and loading. Learn more about grapples

MultiProcessors: An accessory that cuts, shears, and pulverizes.

Pulverizers: Great for breaking down masonry material into smaller pieces.

Shears: Used for cutting steel, cable, and rebar.

Chipping Hammer: Chipping hammers are lightweight, hand-held concrete breakers that can be easily positioned to break vertical and overhead surfaces. By offering a controlled chipping action, these hammers allow operators to precisely chip away only specific areas.

The smallest chipping hammers, powered electrically, pneumatically, or hydraulically, usually weigh between 5 and 30 pounds. As usual, a good indication of the power of the tools is their weight. The heavier the tool, the more powerful it is apt to be. The chipping action of this type of equipment is rapid, ranging from 900 to 3,000 blows per minute.

Because chipping hammers are most often used to break concrete on vertical and overhead surfaces, they must be light. They are maneuvered by holding a handle at the back of the tool and gripping the tool by its shaft with the other hand. Some tools have a second handle along the side. This gives operators control of the tool’s weight and the ability to direct its chipping action at different angles.

By offering a controlled chipping action, these hammers allow operators to precisely chip away only specific areas.

Manufacturers are offering more options than ever in Miami Fort Lauderdale Florida on their chipping hammers, including rotating, shock-absorbing handles, and heat shields.

Demolition Hammer: Demolition hammers are similar to rotary hammers and are used in the same way in terms of delivery hammer blows. However, demolition hammers deliver hammering action only, unlike rotary hammers, which can also be used to bore holes.

What demolition hammers lack in this regard in terms of versatility, however, they make up in punch. The demolition hammer is able to deliver more powerful blows than rotary hammers since they typically have about 35% more power. This is due to the fewer parts in a demolition hammer, and sometimes a longer piston stroke, as well.

While the demolition hammer delivers fewer blows per minute than a rotary hammer, the increased strength of the tool actually makes it a quicker and more efficient means of demolishing concrete and masonry.

Diamond Wire Saw: Wire saws were first developed in the stone quarry industry, and diamond wire saws have been used in concrete demolishing work to cut reinforced concrete since the early 1980s.

A loop of diamond wire mounted on a flywheel driven by a hydraulic or electric motor. Hydraulic drives powered by electric, gasoline, or diesel units are usually preferred on wire saws when cutting reinforced concrete since they are both reversible and provide continuously variable speed. Water is applied to the cut to provide cooling and to flush the cut. Building Demolition Equipment Miami Fort Lauderdale Florida

Diamond wire saws are more efficient than circular saws, able to cut concrete of almost any thickness. This makes them very useful for the kind of heavy demolition found in bridges, damns and thick concrete structures. In addition, they create little dust, noise, and vibration, making them ideal for building demolition work within inhabited structures in Miami Fort Lauderdale Florida.

Hydraulic Concrete Crusher: Hydraulic concrete crushers are used to demolish concrete methodically and efficiently in areas of Miami Fort Lauderdale Florida. Also called smashers, densifiers, processors, secondary crushers, and pulverizers, concrete crushers are used to reduce concrete into smaller easily manageable or recyclable pieces, as well as to separate steel reinforcement from concrete.

Interchangeable jaws in some crushers, including cracking jaws, shear jaws and pulverizing jaws are often used to work along with various types and configurations of jaw teeth in order to better fit the crusher to a particular job.

Secondary concrete crushers usually have some type of pulverizing jaws and are used on jobs where primary building demolition is accomplished by hammers, crushers, blasting, ball and crane, or sawing. In this instance, the primary building demolition work creates large quantities of concrete rubble which the secondary crusher further reduces, separating concrete from reinforcement. Building Demolition Equipment Miami Fort Lauderdale Florida

Hydraulic Splitter: Hydraulic splitters apply lateral forces against the inside of holes drilled into concrete in order to break up concrete with a minimum of noise and flying debris.

About the size of a jackhammer, the tool utilizes a shaft known as a plug-and-feather assembly which, when inserted into a drilled hole and forced downward by the tools piston, creates the lateral forces that break the concrete. No heavy impact is utilized to form the crack, which spreads quickly and without any noise between the pre-drilled holes until the concrete is split into manageable pieces.

The typical hydraulic splitter exerts a force between about 150 and 400 tons, depending on make and model. As with most pieces of equipment of this type, the smaller models with a force capacity on the lower end of the scale are used for more lightweight work, or where the equipment must be able to be handled more easily, such as in horizontal or overhead work. Larger capacity models are capable of splitting mass concrete and hard rock.

Hydraulic splitters may be available in gas- and electrically-powered models but most contractors prefer air-powered hydraulic pumps, as the tools air compressor can also be used to power the drills used to form the holes in the concrete. Multiple hydraulic splitters can be set up to run side-by-side off the same hydraulic pump, allowing for a greater combined splitting force, helpful when breaking up particularly thick or dense concrete.

To correctly operate a splitter, the holes must be drilled straight into the concrete at the exact diameter specified for the splitter, and be deep enough to accommodate the plug when fully extended. The plug and feathers have to be kept well lubricated in order to remain in working condition. Building Demolition Equipment Miami Fort Lauderdale Florida

Pavement Breaker: Hand-held pavement breakers may be thought of as a kind of heavy-duty version of the chipping hammer.

The difference is that pavement breakers are heavier, more powerful tools that are usually operated perpendicular to the ground. Because of this, a T-shaped handle is the most common design for pavement breakers. A few lightweight breakers are designed with a D-shaped handle that allows the operator to pick the breaker up and operate it horizontally.

Like chipping hammers, pavement breakers are powered hydraulically, electrically, or pneumatically. The pounding action of breakers is usually slightly slower than that of chipping hammers, ranging from 800 blows per minute to close to 2,000 blows per minute.

Pavement breakers weigh from 30 to 99 pounds. A good indication of a breaker’s power is its weight.

Pavement breakers weighing between 40 and 50 pounds are particularly useful for removing concrete for partial-depth pavement repair. The weight of these tools gives them the power needed to break up a few inches of concrete without being so heavy that they demolish the entire pavement. Building Demolition Equipment Miami Fort Lauderdale Florida

The pavement breakers weighing 60 pounds and more can handle medium-to-heavy demolition jobs with reinforced concrete, and are used to demolish pavements, roads, and thick concrete. One example of the type of work that the heaviest breakers do is the demolition of high-strength concrete found on airport runways.

Rotary Hammer: Big rotary hammers are known as either SDS-max or spline-drive hammers, depending on whether they accept SDS-max or spline shank bits.

The versatility of the rotary hammer allows it to demolish concrete with a hammer only method, or to deliver rotary hammer action for boring holes in concrete. This is done in the rotary hammer mode by driving twist drills and core bits, or in the hammer only mode to utilize everything from flat chisels to ground rod drivers.

However, this versatility comes at a price, since rotary hammers have an extra drive train that rotates drill bits in the rotary hammer mode. This siphons off energy and decreases efficiency in the hammer-only mode.

Rotary hammers use a battering ram that floats inside a cylinder and is launched and retrieved by a piston. A shock-absorbing airspace between the ram and the piston compresses and drives the ram forward as the piston advances then sucks it back as the piston retracts. Building Demolition Equipment Miami Fort Lauderdale Florida

Hydraulic Hammer: A hydraulic hammer shouldn’t be chosen strictly on the basis of the reach, stability, or hydraulic capacity necessary, but also on the vehicle on which the tool will be mounted. Keep in mind that for a given reach, the heavier the hammer, the heavier the carrier vehicle must be. The weight of the carrier vehicle prevents overturning when the hammer is at the boom’s maximum reach. Selecting a lightweight carrier decreases the boom’s reach and could cause an overturning accident.

Also, remember that while most hydraulic systems run 2000-psi pressure, the flow rate varies. For the light hammers, as little as 5 gallons per minute is required. For the heavy hammers, more than 100 gallons per minute must be supplied. Again, check the hammer and carrier manufacturers’ literature to match the hammer to the vehicle. If necessary, add-on hydraulic power units are available to increase the flow rate.

Mounted Breakers: The speed, versatility, and impact energy of mounted breakers are widely used by contractors to demolish heavily reinforced walls, slabs, and decks.

Excavator-mounted breakers can have production rates of more than 1,100 cubic yards of unreinforced concrete per day. Productivity varies depending on a variety of factors including the type of concrete, accessibility, and operator skill. Building Demolition Equipment Miami Fort Lauderdale Florida

In addition to demolishing concrete, many hammers can be fitted with special tool shapes that allow them to drive piles and sheeting, compact soil, edge trenches, penetrate the frozen ground, and cut asphalt. Building Demolition Equipment Miami Fort Lauderdale Florida

Hammer impact energy is the most important selection criteria when choosing a mounted breaker for a particular job since the hammer must be able to hit the concrete hard enough to fracture it. Only when impact energy is sufficient does impact rate (blows per minute) become a factor.

In factoring impact energy, hammer weight is important but is sometimes confusing. Some manufacturers report the weight of the hammer with the boom bracket, surrounding housing (cradle), and working tool included. Others report just the hammer weight itself.

This is why comparing tool diameter may be the simplest and most accurate means of determining the degree of hammer impact energy. By measuring the tool diameter at the lowest point just inside the hammer and comparing it to the diameter of other tools, impact energy may be reliably measured. This is because the tool diameter is in direct proportion to the piston size. Building Demolition Equipment Miami Fort Lauderdale Florida

Expansive Demolition Agents: The expansive demolition agent is a cementitious powder which is used for demolitions in Miami Fort Lauderdale Florida. Using a drill with a mixing attachment, the powder is mixed in a bucket and poured or tamped into drilled holes. As the mix hardens and expands, the concrete cracks between the drilled holes. As the hairline cracks develop over the slab, they run outward into each other and grow wider, until the slab literally falls apart under an expansive force that can exceed 12,000 psi. Building Demolition Equipment Miami Fort Lauderdale Florida

Used correctly, expansive demolition agents produce little dust or debris. The only labor involved is in drilling the holes, mixing and applying the agent, and then hauling the broken up pieces of concrete away.

One cautionary note: With expansive demolition, agents involves a phenomenon known as “blow- out.” This happens if the powder mix gets too hot and reacts with the water too quickly for the material to expand laterally. The result can range from a puff of smoke to a loud gunshot-like sound that can send hardened mix 30 feet into the air. Since blow-outs are unpredictable, safety procedures require workers to stay well away from the drilled holes once the mix has been poured into them. If a blow-out does occur, however, it usually has little effect on the project, since the remaining mix in the hole is usually still effective enough to crack the concrete. Building Demolition Equipment Miami Fort Lauderdale Florida

Pneumatic Hammer: While pneumatic hammers were once considered state-of-the-art in the United States, they only account for a small portion of total hammers in use today. There are still a number of advantages in using pneumatic hammers, however. This include:

  • They can be mounted on lighter carriers since their external air compressor negates the extra hydraulic demands of a hydraulic hammer.
  • Mounting an air hammer requires only mechanical changes no hydraulic connections, systems to service, or plumbing kits.
  • Pneumatic hammers work better in confined spaces than hydraulic hammers due to their high weight-to-power ratio.
  • Pneumatic hammers are more conducive to underwater use, having few, if any, seals.
